Negation in Language and Beyond (NegLaB). 2024 – . Funded by DFG (SFB 1629).
Description
Negation is a fundamental and unique property of human language since it allows us to reason about what is not the case. It does not only express a clearly defined grammatical function, it also interacts with various aspects of grammar and cognition. The acquisition and processing of negation encompass linguistic as well as non-linguistic cognitive procedures. Hence, negation constitutes an ideal testing ground to differentiate cognitive mechanisms that are grammatical in nature from those that are shared with other cognitive domains, such as memory, attention, decision making and cognitive control. We intend to explore how the expression of negation is cross-linguistically associated with grammatical and non-linguistic cognitive operations and also whether the operations observed in negative utterances are part of negation itself or, rather, arises as an effect of the grammatical system and cognitive functions. While the semantics of negation is generally analyzed as a unique propositional operator, its morphosyntactic expression is much more varied and often involves more than one morphological exponent. Hence, there is a tension between a rich morphosyntax and a more straightforward semantics. The semantics of negation leads one to expect negation to be expressed by a single morpheme positioned at the beginning of the clause (Neg-Only Hypothesis). The rich and variable morphosyntax leads us to expect that negation requires a number of conditions in the semantics (Neg-Plus Hypothesis). We aim to solve this puzzle covering several empirical domains. More grammatical effects than semantics would lead us to expect are visible in the interaction between negative utterances and the cognitive processing and semantic evaluation of alternative propositions. This is reflected in acquisition, since children produce negative utterances relatively early, but all the aspects of negation take a rather long time to be acquired. Downstream effects of this can be seen in adult processing as the comprehension of negative sentences is costlier than for positive sentences. This is supposedly due to the inhibition of the corresponding positive sentence that is necessary for the interpretation of negative statements. Our exploration into the way negation and other grammatical categories or non-linguistic cognitive functions interact will lead us to identify how negation functions in natural language and how it favors or hinders other (extra-)grammatical components or processes. Why do some of them need to occur together with negation (e.g., negative polarity items) and why are others incompatible with it (as some types of imperatives)? Our general aim is to develop a theoretical perspective on the way negation manifests itself in natural language, how it is acquired and processed, and why it varies so much across languages. Thereby, we will gain a better understanding of the connections between linguistic competence and general cognition.

Virtual Reality Sustained Multimodal Distributional Semantics for Gestures in Dialogue (GeMDiS). 2021 – . Funded by DFG (SPP 2392).
Description
Both corpus-based linguistics and contemporary computational linguistics rely on the use of often large, linguistic resources. The expansion of the linguistic subject area to include visual means of communication such as gesticulation has not yet been backed up with corresponding corpora. This means that “multimodal linguistics” and dialogue theory cannot participate in established distributional methods of corpus linguistics and computational semantics. The main reason for this is the difficulty of collecting multimodal data in an appropriate way and at an appropriate scale. Using the latest VR-based recording methods, the GeMDiS project aims to close this data gap and to investigate visual communication by means of machine-based methods and innovative use of neuronal and active learning for small data using the systematic reference dimensions of associativity and contiguity of the features of visual and non-visual communicative signs.

Berufspraktische Bildungsprozesse im Recht- und Lehramtsreferendariat sowie der Medizin unter Nutzung digitaler Medien (BRIDGE). 2020 – 2023. Funded by BMBF (01JD1906B).
Description
Die Nutzung von Onlinemedien steigt in allen Bildungsbereichen zunehmend an. Auch für den Berufseinstieg nutzen Lernende immer häufiger online verfügbare Medien. Ob sich das Nutzungsverhalten je nach Beruf unterscheidet und ob es berufsspezifische Unterschiede gibt, ist bislang nicht erforscht. Hier setzt das Forschungsprojekt der Johannes Gutenberg-Universität Mainz und der Johann Wolfgang Goethe-Universität Frankfurt an. Die Wissenschaftlerinnen und Wissenschaftler untersuchen, wie Berufseinsteigende der Medizin im Praktischen Jahr, Lehramts- sowie Rechtsreferendarinnen und -referendare online verfügbare Medien nutzen. Hierbei vergleicht das interdisziplinäre Team die generelle mit der berufsspezifischen Nutzung von Onlinemedien anhand einer repräsentativen Stichprobe im Längsschnitt. Mithilfe von innovativen Ansätzen aus der Computerlinguistik und aus dem Bereich der Learning Analytics werden Online-Trainings entwickelt und die Lernprozesse der Probanden untersucht. Um die Daten multiperspektivisch zu interpretieren, wird eng mit der Praxis zusammengearbeitet. Das Team der Universität Mainz koordiniert das Verbundprojekt und bringt die wirtschaftspädagogische und rechtswissenschaftliche Perspektive sowie Expertise zur Kompetenzentwicklung ein. Die repräsentative und methodenintegrative Studie liefert wissenschaftliche Erkenntnisse zum Einfluss und zur digitalen Förderbarkeit der berufsbezogenen Mediennutzung in der Berufspraxis. Außerdem sind Ergebnisse zu erwarten, die zur Gestaltung der Verbindung von formalen und non-formalen Lerngelegenheiten genutzt werden können. Praxispartner, wie zum Beispiel Ausbildnerinnen und Ausbildner, können die entwickelten adaptiven Trainingskonzepte praktisch anwenden und nutzen.

  abstract  = {The number of multilingual texts in the World Wide Web (WWW) is
               increasing dramatically and a multilingual economic zone like
               the European Union (EU) requires the availability of multilingual
               Natural Language Processing (NLP) tools. Due to a rapid development
               of NLP tools, many lexical, syntactic, semantic and other linguistic
               features have been used in different NLP applications. However,
               there are some situations where these features can not be used
               due the application type or unavailability of NLP resources for
               some of the languages. That is why an application that is intended
               to handle multilingual texts must have features that are not dependent
               on a particular language and specific linguistic tools. In this
               thesis, we will focus on two such applications: text readability
               and source and translation classification. In this thesis, we
               provide 18 features that are not only suitable for both applications,
               but are also language and linguistic tools independent. In order
               to build a readability classifier, we use texts from three different
               languages: English, German and Bangla. Our proposed features achieve
               a classification accuracy that is comparable with a classifier
               using 40 linguistic features. The readability classifier achieves
               a classification F-score of 74.21\% on the English Wikipedia corpus,
               an F-score of 75.47\% on the English textbook corpus, an F-score
               of 86.46\% on the Bangla textbook corpus and an F-score of 86.26\%
               on the German GEO/GEOLino corpus. We used more than two million
               sentence pairs from 21 European languages in order to build the
               source and translation classifier. The classifier using the same
               eighteen features achieves a classification accuracy of 86.63\%.
               We also used the same features to build a classifier that classifies
               translated texts based on their origin. The classifier achieves
               classification accuracy of 75\% for texts from 10 European languages.
               In this thesis, we also provide four different corpora, three
               for text readability analysis and one for corpus based translation
               studies.}

  abstract  = {This thesis bridges between two scientific fields -- linguistics
               and computer science -- in terms of Linguistic Networks. From
               the linguistic point of view we examine whether languages can
               be distinguished when looking at network topology of different
               linguistic networks. We deal with up to 17 languages and ask how
               far the methods of network theory reveal the peculiarities of
               single languages. We present and apply network models from different
               levels of linguistic representation: syntactic, phonological and
               morphological. The network models presented here allow to integrate
               various linguistic features at once, which enables a more abstract,
               holistic view at the particular language. From the point of view
               of computer science we elaborate the instrumentarium of network
               theory applying it to a new field. We study the expressiveness
               of different network features and their ability to characterize
               language structure. We evaluate the interplay of these features
               and their goodness in the task of classifying languages genealogically.
               Among others we compare network features related to: average degree,
               average geodesic distance, clustering, entropy-based indices,
               assortativity, centrality, compactness etc. We also propose some
               new indices that can serve as additional characteristics of networks.
               The results obtained show that network models succeed in classifying
               related languages, and allow to study language structure in general.
               The mathematical analysis of the particular network indices brings
               new insights into the nature of these indices and their potential
               when applied to different networks.},

               was collected and published - GerParCor. Through GerParCor, it
               became possible to provide for the first time various parliamentary
               protocols which were not available digitally and, moreover, could
               not be retrieved and processed in a uniform manner. Furthermore,
               GerParCor was additionally preprocessed using NLP methods and
               made available in XMI format. In this paper, GerParCor is significantly
               updated by including all new parliamentary protocols in the corpus,
               as well as adding and preprocessing further parliamentary protocols
               previously not covered, so that a period up to 1797 is now covered.
               Besides the integration of a new, state-of-the-art and appropriate
               NLP preprocessing for the handling of large text corpora, this
               update also provides an overview of the further reuse of GerParCor

  abstract  = {Purpose: Based on the examples of English and German, we investigate
               to what extent parsers trained on modern variants of these languages
               can be transferred to older language levels without loss. Methods:
               We developed a treebank called DoTT (https://github.com/texttechnologylab/DoTT)
               which covers, roughly, the time period from 1800 until today,
               in conjunction with the further development of the annotation
               tool DependencyAnnotator. DoTT consists of a collection of diachronic
               corpora enriched with dependency annotations using 3 parsers,
               6 pre-trained language models, 5 newly trained models for German,
               and two tag sets (TIGER and Universal Dependencies). To assess
               how the different parsers perform on texts from different time
               periods, we created a gold standard sample as a benchmark. Results:
               We found that the parsers/models perform quite well on modern
               texts (document-level LAS ranging from 82.89 to 88.54) and slightly
               worse on older texts, as expected (average document-level LAS
               84.60 vs. 86.14), but not significantly. For German texts, the
               (German) TIGER scheme achieved slightly better results than UD.
               Conclusion: Overall, this result speaks for the transferability
               of parsers to past language levels, at least dating back until
               around 1800. This very transferability, it is however argued,
               means that studies of language change in the field of dependency
               syntax can draw on dependency distance but miss out on some grammatical
               phenomena.},

  abstract  = {We present HyperCausal, a 3D hypertext visualization framework
               for exploring causal inference in generative Large Language Models
               (LLMs). HyperCausal maps the generative processes of LLMs into
               spatial hypertexts, where tokens are represented as nodes connected
               by probability-weighted edges. The edges are weighted by the prediction
               scores of next tokens, depending on the underlying language model.
               HyperCausal facilitates navigation through the causal space of
               the underlying LLM, allowing users to explore predicted word sequences
               and their branching. Through comparative analysis of LLM parameters
               such as token probabilities and search algorithms, HyperCausal
               provides insight into model behavior and performance. Implemented
               using the Hugging Face transformers library and Three.js, HyperCausal
               ensures cross-platform accessibility to advance research in natural
               language processing using concepts from hypertext research. We
               demonstrate several use cases of HyperCausal and highlight the
               potential for detecting hallucinations generated by LLMs using
               this framework. The connection with hypertext research arises
               from the fact that HyperCausal relies on user interaction to unfold
               graphs with hierarchically appearing branching alternatives in
               3D space. This approach refers to spatial hypertexts and early
               concepts of hierarchical hypertext structures. A third connection
               concerns hypertext fiction, since the branching alternatives mediated
               by HyperCausal manifest non-linearly organized reading threads
               along artificially generated texts that the user decides to follow
               optionally depending on the reading context.},

  abstract  = {Simulation-based learning is a method in which learners learn
               to master real-life scenarios and tasks from simulated application
               contexts. It is particularly suitable for the use of VR technologies,
               as these allow immersive experiences of the targeted scenarios.
               VR methods are also relevant for studies on online learning, especially
               in groups, as they provide access to a variety of multimodal learning
               and interaction data. However, VR leads to a trade-off between
               technological conditions of the observability of such data and
               the openness of learner behavior. We present Va.Si.Li-Lab, a VR-L
               ab for Simulation-based Learn ing developed to address this trade-off.
               Va.Si.Li-Lab uses a graph-theoretical model based on hypergraphs
               to represent the data diversity of multimodal learning and interaction.
               We develop this data model in relation to mono- and multimodal,
               intra- and interpersonal data and interleave it with ISO-Space
               to describe distributed multiple documents from the perspective
               of their interactive generation. The paper adds three use cases

               scene framework using SemAF (Semantic Annotation Framework) as
               a scheme for annotating discourse structures. SeSB integrates
               a variety of tools and resources by using SemAF and UIMA as a
               unified data structure to generate 3D scenes from textual descriptions.
               Based on VR, SeSB allows its users to change annotations through
               body movements instead of symbolic manipulations: from annotations
               in texts to corrections in editing steps to adjustments in generated
               scenes, all this is done by grabbing and moving objects. We evaluate
               SeSB in comparison with a state-of-the-art open source text-to-scene
               method (the only one which is publicly available) and find that

  abstract  = {During the last thirty years a variety of hypertext approaches
               and virtual environments -- some virtual hypertext environments
               -- have been developed and discussed. Although the development
               of virtual and augmented reality technologies is rapid and improving,
               and many technologies can be used at affordable conditions, their
               usability for hypertext systems has not yet been explored. At
               the same time, even for virtual three-dimensional virtual and
               augmented environments, there is no generally accepted concept
               that is similar or nearly as elegant as hypertext. This gap will
               have to be filled in the next years and a good concept should
               be developed; in this article we aim to contribute in this direction
               and also introduce a prototype for a possible implementation of
               criteria for virtual hypertext simulations.},

               integration of ever new tools. Since there are no adequate frameworks
               for these purposes in the field of NLP, and especially in the
               context of UIMA, that are not outdated or unusable for security
               reasons, we present a new approach to address the latter task:
               Docker Unified UIMA Interface (DUUI), a scalable, flexible, lightweight,
               and feature-rich framework for automatic distributed analysis
               of text corpora that leverages Big Data experience and virtualization
               with Docker. We evaluate DUUI{'}s communication approach against
               a state-of-the-art approach and demonstrate its outstanding behavior
               in terms of time efficiency, enabling the analysis of big text

               approaches based on static models in many respects. This success
               has in turn prompted research that reveals a number of biases
               in the language models generated by transformers. In this paper
               we utilize this research on biases to investigate to what extent
               transformer-based language models allow for extracting knowledge
               about object relations (X occurs in Y; X consists of Z; action
               A involves using X).To this end, we compare contextualized models
               with their static counterparts. We make this comparison dependent
               on the application of a number of similarity measures and classifiers.
               Our results are threefold:Firstly, we show that the models combined
               with the different similarity measures differ greatly in terms
               of the amount of knowledge they allow for extracting. Secondly,
               our results suggest that similarity measures perform much worse
               than classifier-based approaches. Thirdly, we show that, surprisingly,
               static models perform almost as well as contextualized models

  title     = {On latent domain-specific textual preferences in solving Internet-based
               generic tasks among graduates/young professionals from three domains},
  abstract  = {Although Critical Online Reasoning (COR) is often viewed as a
               general competency (e.g. Alexander et al. 2016), studies have
               found evidence supporting their domain-specificity (Toplak et
               al. 2002). To investigate this assumption, we focus on commonalities
               and differences in textual preferences in solving COR-related
               tasks between graduates/young professionals from three domains.
               For this reason, we collected data by requiring participants to
               solve domain-specific (DOM-COR) and generic (GEN-COR) tasks in
               an authentic Internet-based COR performance assessment (CORA),
               allowing us to disentangle the assumed components of COR abilities.
               Here, we focus on GEN-COR to distinguish between different groups
               of graduates from the three disciplines in the context of generic
               COR tasks. We present a computational model for educationally
               relevant texts that combines features at multiple levels (lexical,
               syntactic, semantic). We use machine learning to predict domain-specific
               group membership based on documents consulted during task solving.
               A major contribution of our analyses is a multi-part text classification
               system that contrasts human annotation and rating of the documents
               used with a semi-automatic classification to predict the document
               type of web pages. That is, we work with competing classifications
               to support our findings. In this way, we develop a computational
               linguistic model that correlates GEN-COR abilities with properties
               of documents consulted for solving the GEN-COR tasks. Results
               show that participants from different domains indeed inquire different
               sets of online sources for the same task. Machine learning-based
               classifications show that the distributional differences can be
               reproduced by computational linguistic models.},

  abstract  = {Various historical languages, which used to be lingua franca of
               science and arts, deserve the attention of current NLP research.
               In this work, we take the first data-driven steps towards this
               research line for Classical Arabic (CA) by addressing named entity
               recognition (NER) and topic modeling (TM) on the example of CA
               literature. We manually annotate the encyclopedic work of Tafsir
               Al-Tabari with span-based NEs, sentence-based topics, and span-based
               subtopics, thus creating the Tafsir Dataset with over 51,000 sentences,
               the first large-scale multi-task benchmark for CA. Next, we analyze
               our newly generated dataset, which we make open-source available,
               with current language models (lightweight BiLSTM, transformer-based
               MaChAmP) along a novel script compression method, thereby achieving
               state-of-the-art performance for our target task CA-NER. We also
               show that CA-TM from the perspective of historical topic models,
               which are central to Arabic studies, is very challenging. With
               this interdisciplinary work, we lay the foundations for future
               research on automatic analysis of CA literature.}

               of annotation tools, a conceptual change in annotation models
               and processes is also on the horizon. It is diagnosed that these
               changes are bound up with multi-media and multi-perspective facilities
               of annotation tools, in particular when considering virtual reality
               (VR) and augmented reality (AR) applications, their potential
               ubiquitous use, and the exploitation of externally trained natural
               language pre-processing methods. Such developments potentially
               lead to a dynamic and exploratory heuristic construction of the
               annotation process. With TextAnnotator an annotation suite is
               introduced which focuses on multi-mediality and multi-perspectivity
               with an interoperable set of task-specific annotation modules
               (e.g., for word classification, rhetorical structures, dependency
               trees, semantic roles, and more) and their linkage to VR and mobile
               implementations. The basic architecture and usage of TextAnnotator
               is described and related to the above mentioned shifts in the
               field.}

               CB Botafogo (1992) are important graph indices in applications
               of complex network theory to real-world problems. Here, for simple
               connected undirected graphs G of order n, we study the behavior
               of L(G) and CB(G), subject to the condition that their order |V(G)|

               lies within the interval [0;1/3] and [2/3;1], respectively. Moreover,
               for any not necessarily rational number β ∈ [0;1/3] (α ∈ [2/3;1])
               we show how to construct the sequence of graphs {G}, |V(G)| =
               n → ∞, for which the limit of L(G)/n (CB(G)) is exactly β (α)
               (Theorems 1 and 2). Based on these results, our work points to
               novel classification possibilities of graphs at the node level

               this effect with respect to word embeddings. That is, we analyze
               the effects of CR on six different embedding methods and evaluate
               them in the context of seven lexical-semantic evaluation tasks
               and instantiation/hypernymy detection. Especially in the last
               tasks we hoped for a significant increase in performance. We show
               that all word embedding approaches do not benefit significantly
               from pronoun substitution. The measurable improvements are only
               marginal (around 0.5\% in most test cases). We explain this result
               with the loss of contextual information, reduction of the relative
               occurrence of rare words and the lack of pronouns to be replaced.},

  abstract  = {Current sentence boundary detectors split documents into sequentially
               ordered sentences by detecting their beginnings and ends. Sentences,
               however, are more deeply structured even on this side of constituent
               and dependency structure: they can consist of a main sentence
               and several subordinate clauses as well as further segments (e.g.
               inserts in parentheses); they can even recursively embed whole
               sentences and then contain multiple sentence beginnings and ends.
               In this paper, we introduce a tool that segments sentences into
               tree structures to detect this type of recursive structure. To
               this end, we retrain different constituency parsers with the help
               of modified training data to transform them into sentence segmenters.
               With these segmenters, documents are mapped to sequences of sentence-related
               “logical document structures”. The resulting segmenters aim to
               improve downstream tasks by providing additional structural information.
               In this context, we experiment with German dependency parsing.
               We show that for certain sentence categories, which can be determined
               automatically, improvements in German dependency parsing can be
               achieved using our segmenter for preprocessing. The assumption
               suggests that improvements in other languages and tasks can be
               achieved.},

  abstract  = {People's visual perception is very pronounced and therefore it
               is usually no problem for them to describe the space around them
               in words. Conversely, people also have no problems imagining a
               concept of a described space. In recent years many efforts have
               been made to develop a linguistic concept for spatial and spatial-temporal
               relations. However, the systems have not really caught on so far,
               which in our opinion is due to the complex models on which they
               are based and the lack of available training data and automated
               taggers. In this paper we describe a project to support spatial
               annotation, which could facilitate annotation by its many functions,
               but also enrich it with many more information. This is to be achieved
               by an extension by means of a VR environment, with which spatial
               relations can be better visualized and connected with real objects.
               And we want to use the available data to develop a new state-of-the-art
               tagger and thus lay the foundation for future systems such as
               improved text understanding for Text2Scene.},

               We describe recent advances in the development of lemmatizers
               and test them against the Capitularies corpus (comprising Frankish
               royal edicts, mid-6th to mid-9th century), a corpus created as
               a reference for processing Medieval Latin. We also consider the

               modern NLP tools for this language. Therefore, the EvaLatin Shared
               Task for Lemmatization and Part-of-Speech (POS) tagging was published
               in the LT4HALA workshop. In our work, we dealt with the second
               EvaLatin task, that is, POS tagging. Since most of the available
               Latin word embeddings were trained on either few or inaccurate
               data, we trained several embeddings on better data in the first
               step. Based on these embeddings, we trained several state-of-the-art
               taggers and used them as input for an ensemble classifier called
               LSTMVoter. We were able to achieve the best results for both the
               cross-genre and the cross-time task (90.64\% and 87.00\%) without
               using additional annotated data (closed modality). In the meantime,
               we further improved the system and achieved even better results
               (96.91\% on classical, 90.87\% on cross-genre and 87.35\% on cross-time).},

               humanities and Natural Language Processing (NLP) is a common task
               of research projects. At the same time, the annotation of corpora
               is certainly the most time- and cost-intensive component in research
               projects and often requires a high level of expertise according
               to the research interest. However, for the annotation of texts,
               a wide range of tools is available, both for automatic and manual
               annotation. Since the automatic pre-processing methods are not
               error-free and there is an increasing demand for the generation
               of training data, also with regard to machine learning, suitable
               annotation tools are required. This paper defines criteria of
               flexibility and efficiency of complex annotations for the assessment
               of existing annotation tools. To extend this list of tools, the
               paper describes TextAnnotator, a browser-based, multi-annotation
               system, which has been developed to perform platform-independent
               multimodal annotations and annotate complex textual structures.
               The paper illustrates the current state of development of TextAnnotator
               and demonstrates its ability to evaluate annotation quality (inter-annotator
               agreement) at runtime. In addition, it will be shown how annotations
               of different users can be performed simultaneously and collaboratively
               on the same document from different platforms using UIMA as the

               annotation of texts with visual annotation support, integration
               of knowledge bases and, by pipelining the TextImager, a rich variety
               of pre-processing and automatic annotation tools. It includes
               a variety of modules for the annotation of texts, which contains
               the annotation of argumentative, rhetorical, propositional and
               temporal structures as well as a module for named entity linking
               and rapid annotation of named entities. Especially the modules
               for annotation of temporal, argumentative and propositional structures
               are currently unique in web-based annotation tools. The TextAnnotator,
               which allows the annotation of texts as a platform, is divided
               into a front- and a backend component. The backend is a web service
               based on WebSockets, which integrates the UIMA Database Interface
               to manage and use texts. Texts are made accessible by using the
               ResourceManager and the AuthorityManager, based on user and group
               access permissions. Different views of a document can be created
               and used depending on the scenario. Once a document has been opened,
               access is gained to the annotations stored within annotation views
               in which these are organized. Any annotation view can be assigned
               with access permissions and by default, each user obtains his
               or her own user view for every annotated document. In addition,
               with sufficient access permissions, all annotation views can also
               be used and curated. This allows the possibility to calculate
               an Inter-Annotator-Agreement for a document, which shows an agreement
               between the annotators. Annotators without sufficient rights cannot
               display this value so that the annotators do not influence each
               other. This contribution is intended to reflect the current state
               of development of TextAnnotator, demonstrate the possibilities
               of an instantaneous Inter-Annotator-Agreement and trigger a discussion
               about further functions for the community.},

  abstract  = {The storage of data in public repositories such as the Global
               Biodiversity Information Facility (GBIF) or the National Center
               for Biotechnology Information (NCBI) is nowadays stipulated in
               the policies of many publishers in order to facilitate data replication
               or proliferation. Species occurrence records contained in legacy
               printed literature are no exception to this. The extent of their
               digital and machine-readable availability, however, is still far
               from matching the existing data volume (Thessen and Parr 2014).
               But precisely these data are becoming more and more relevant to
               the investigation of ongoing loss of biodiversity. In order to
               extract species occurrence records at a larger scale from available
               publications, one has to apply specialised text mining tools.
               However, such tools are in short supply especially for scientific
               literature in the German language.The Specialised Information
               Service Biodiversity Research*1 BIOfid (Koch et al. 2017) aims
               at reducing this desideratum, inter alia, by preparing a searchable
               text corpus semantically enriched by a new kind of multi-label
               annotation. For this purpose, we feed manual annotations into
               automatic, machine-learning annotators. This mixture of automatic
               and manual methods is needed, because BIOfid approaches a new
               application area with respect to language (mainly German of the
               19th century), text type (biological reports), and linguistic
               focus (technical and everyday language).We will present current
               results of the performance of BIOfid’s semantic search engine
               and the application of independent natural language processing
               (NLP) tools. Most of these are freely available online, such as
               TextImager (Hemati et al. 2016). We will show how TextImager is
               tied into the BIOfid pipeline and how it is made scalable (e.g.
               extendible by further modules) and usable on different systems
               (docker containers).Further, we will provide a short introduction
               to generating machine-learning training data using TextAnnotator
               (Abrami et al. 2019) for multi-label annotation. Annotation reproducibility
               can be assessed by the implementation of inter-annotator agreement
               methods (Abrami et al. 2020). Beyond taxon recognition and entity
               linking, we place particular emphasis on location and time information.
               For this purpose, our annotation tag-set combines general categories
               and biology-specific categories (including taxonomic names) with
               location and time ontologies. The application of the annotation
               categories is regimented by annotation guidelines (Lücking et
               al. 2020). Within the next years, our work deliverable will be
               a semantically accessible and data-extractable text corpus of
               around two million pages. In this way, BIOfid is creating a new
               valuable resource that expands our knowledge of biodiversity and
               its determinants.},

  abstract  = {We test the hypothesis that the extent to which one obtains information
               on a given topic through Wikipedia depends on the language in
               which it is consulted. Controlling the size factor, we investigate
               this hypothesis for a number of 25 subject areas. Since Wikipedia
               is a central part of the web-based information landscape, this
               indicates a language-related, linguistic bias. The article therefore
               deals with the question of whether Wikipedia exhibits this kind
               of linguistic relativity or not. From the perspective of educational
               science, the article develops a computational model of the information
               landscape from which multiple texts are drawn as typical input
               of web-based reading. For this purpose, it develops a hybrid model
               of intra- and intertextual similarity of different parts of the
               information landscape and tests this model on the example of 35
               languages and corresponding Wikipedias. In the way it measures
               the similarities of hypertexts, the article goes beyond existing
               approaches by examining their structural and semantic aspects
               intra- and intertextually. In this way it builds a bridge between
               reading research, educational science, Wikipedia research and
               computational linguistics.},

               In order to face this problem, the so-called VAnnotatoR was developed,

               attracting increasing interest in many scientific disciplines.
               Locating chemical named entities in the literature is an essential

  abstract  = {Modern annotation tools should meet at least the following general
               requirements: they can handle diverse data and annotation levels
               within one tool, and they support the annotation process with
               automatic (pre-)processing outcomes as much as possible. We developed
               a framework that meets these general requirements and that enables
               versatile and browser-based annotations of texts, the TextAnnotator.
               It combines NLP methods of pre-processing with methods of flexible
               post-processing. Infact, machine learning (ML) requires a lot
               of training and test data, but is usually far from achieving perfect
               results. Producing high-level annotations for ML and post-correcting
               its results are therefore necessary. This is the purpose of TextAnnotator,
               which is entirely implemented in ExtJS and provides a range of
               interactive visualizations of annotations. In addition, it allows
               for flexibly integrating knowledge resources, e.g. in the course
               of post-processing named entity recognition. The paper describes
               TextAnnotator’s architecture together with three use cases: annotating
               temporal structures, argument structures and named entity linking.}

               use it to train domain-specific embeddings which we incorporate
               in our model training. We achieve a result of 89.76{\%} F1-score
               using pre-trained embeddings and are able to improve these results
               to 90.52{\%} F1-score using specialized embeddings.}

               text interpretation. As a point of reference, we focus on the
               complexity of educational texts. To open up a broader basis for
               representing phenomena of context sensitivity, we integrate a
               learning theory (i.e., the Cognitive Load Theory) with a theory
               of discourse comprehension (i.e., the Construction Integration
               Model) and a theory of cognitive semantics (i.e., the theory of
               Conceptual Spaces). The aim is to construct measures that view
               text complexity as a relational attribute by analogy to the relational
               concept of meaning in situation semantics. To this end, we reconstruct
               the situation semantic notion of relational meaning from the perspective
               of a computationally informed cognitive semantics. The aim is
               to prepare the development of measurements for predicting learning
               outcomes in the form of positive or negative learning. This prediction
               ideally depends on the underlying learning material, the learner's
               situational context, and knowledge retrieved from his or her long-term
               memory, which he or she uses to arrive at coherent mental representations
               of the underlying texts. Finally, our model refers to machine
               learning as a tool for modeling such memory content. In this way,
               the chapter integrates approaches from different disciplines (linguistic
               semantics, computational linguistics, cognitive science, and data
               science).},

  abstract  = {This chapter develops a computational linguistic model for analyzing
               and comparing multilingual data as well as its application to
               a large body of standardized assessment data from higher education.
               The approach employs both an automatic and a manual annotation
               of the data on several linguistic layers (including parts of speech,
               text structure and content). Quantitative features of the textual
               data are explored that are related to both the students' (domain-specific
               knowledge) test results and their level of academic experience.
               The respective analysis involves statistics of distance correlation,
               text categorization with respect to text types (questions and
               response options) as well as languages (English and German), and
               network analysis to assess dependencies between features. The
               correlation between correct test results of students and linguistic
               features of the verbal presentations of tests indicate to what
               extent language influences higher education test performance.
               It has also been found that this influence relates to specialized
               language. Thus, this integrative modeling approach contributes
               a test basis for a large-scale analysis of learning data and points
               to a number of subsequent, more detailed research questions.},

               fingerprints of such trees to predict the author of the underlying
               sentences. The chapter makes a first attempt to create such fingerprints
               for sentence categorization via the detour of text categorization.
               We show that at text level, aggregated dependency structures actually
               provide information about authorship. At the same time, we show
               that this does not hold for topic detection. We evaluate our model
               using a quarter of a million sentences collected in two corpora:
               the first is sampled from literary texts, the second from Wikipedia
               articles. As a second finding of our approach, we show that quantitative
               models of dependency structure do not yet allow for detecting
               syntactic alignment in written communication. We conclude that
               this is mainly due to effects of lexical alignment on syntactic
               alignment.},

               user-specific queries. In a pilot project we focus on German publications
               on the distribution and ecology of vascular plants, birds, moths
               and butterflies extending back to the Linnaeus period about 250
               years ago. The three organism groups have been selected according
               to current demands of the relevant research community in Germany.
               The text corpus defined for this purpose comprises over 400 volumes
               with more than 100,000 pages to be digitized and will be complemented
               by journals from other digitization projects, copyright-free and
               project-related literature. With TextImager (Natural Language
               Processing & Text Visualization) and TextAnnotator (Discourse
               Semantic Annotation) we have already extended and launched tools
               that focus on the text-analytical section of our project. Furthermore,
               taxonomic and anatomical ontologies elaborated by us for the taxa
               prioritized by the project’s target group - German institutions
               and scientists active in biodiversity research - are constantly
               improved and expanded to maximize scientific data output. Our
               poster describes the general workflow of our project ranging from
               literature acquisition via software development, to data availability
               on the BIOfid web portal (http://biofid.de/), and the implementation
               into existing platforms which serve to promote global accessibility
               of biodiversity data.},

               (DDC), an international standard for topic classification in libraries.
               We introduce nnDDC, a largely language-independent neural network-based
               classifier for DDC-related topic classification, which we optimized
               using a wide range of linguistic features to achieve an F-score
               of 87.4\%. To show that our approach is language-independent,
               we evaluate nnDDC using up to 40 different languages. We derive
               a topic model based on nnDDC, which generates probability distributions
               over semantic units for any input on sense-, word- and text-level.
               Unlike related approaches, however, these probabilities are estimated
               by means of nnDDC so that each dimension of the resulting vector
               representation is uniquely labeled by a DDC class. In this way,
               we introduce a neural network-based Classifier-Induced Semantic
               Space (nnCISS).},

               index originally introduced for measuring structural characteristics

               graphs (Mehler, 2008) observed its limit behaviour to be equal
               1. The striking question concerning this finding was whether this
               limit behaviour resulted from the specifics of small-world graphs
               or was simply an artefact. In this paper, we determine the necessary
               and sufficient conditions for any sequence of connected graphs
               resulting in a limit value of CB = 1 which can be generalized
               with some consideration for the case of disconnected graph classes
               (Theorem 3). This result can be applied to many well-known classes
               of connected graphs. Here, we illustrate it by considering four
               examples. In fact, our proof-theoretical approach allows for quickly
               obtaining the limit value of compactness for many graph classes

               thematic and participatory dynamics of collaboratively generated
               lexical networks. This is done by example of Wiktionary. Starting
               from a network-theoretical model in terms of so-called multi-layer
               networks, we describe Wiktionary as a scale-free lexicon. Systems
               of this sort are characterized by the fact that their content-related
               dynamics is determined by the underlying dynamics of collaborating
               authors. This happens in a way that social structure imprints
               on content structure. According to this conception, the unequal
               distribution of the activities of authors results in a correspondingly
               unequal distribution of the information units documented within
               the lexicon. The paper focuses on foundations for describing such
               systems starting from a parameter space which requires to deal
               with Wiktionary as an issue in big data analysis. In German: Der

               Modell in Form so genannter Mehrebenennetzwerke wird Wiktionary
               als ein skalenfreies Lexikon beschrieben. Systeme dieser Art zeichnen
               sich dadurch aus, dass ihre inhaltliche Dynamik durch die zugrundeliegende
               Kollaborationsdynamik bestimmt wird, und zwar so, dass sich die
               soziale Struktur der entsprechenden inhaltlichen Struktur aufprägt.
               Dieser Auffassung gemäß führt die Ungleichverteilung der Aktivitäten

               that allow for browsing syntagmatic and paradigmatic relations
               among the constituents of its input texts. In this way, relations
               of text reuse can be explored together with lexical relations
               within the same literary memory information system. Beyond that,
               Wikidition contains a module for automatic lexiconisation to extract
               author specific vocabularies. Based on linkification and lexiconisation,
               Wikidition does not only allow for traversing input corpora on
               different (lexical, sentential and textual) levels. Rather, its
               readers can also study the vocabulary of authors on several levels
               of resolution including superlemmas, lemmas, syntactic words and
               wordforms. We exemplify Wikidition by a range of literary texts
               and evaluate it by means of the apparatus of quantitative network
               analysis.},

               and register-related dynamics. In this chapter we present such
               a joint endeavor that ranges from resource formation via preprocessing
               to network-based text representation and classification. We start
               with presenting the so-called TTLab Latin Tagger (TLT) that preprocesses
               texts of classical and medieval Latin. Its lexical resource in
               the form of the Frankfurt Latin Lexicon (FLL) is also briefly
               introduced. As a first test case for showing the expressiveness
               of these resources, we perform a tripartite classification task
               of authorship attribution, genre detection and a combination thereof.
               To this end, we introduce a novel text representation model that
               explores the core structure (the so-called coreness) of lexical
               network representations of texts. Our experiment shows the expressiveness
               of this representation format and mediately of our Latin preprocessor.},

  abstract  = {Currently, a large number of different lexica is available for
               English. However, substantial and freely available fullform lexica
               with a high number of named entities are rather rare even in the
               case of this lingua franca. Existing lexica are often limited
               in several respects as explained in Section 2. What is missing
               so far is a freely available substantial machine-readable lexical
               resource of English that contains a high number of word forms
               and a large collection of named entities. In this paper, we describe
               a procedure to generate such a resource by example of English.
               This lexicon, henceforth called ColLex.EN (for Collecting Lexica
               for English ), will be made freely available to the public 1.
               In this paper, we describe how ColLex.EN was collected from existing
               lexical resources and specify the statistical procedures that
               we developed to extend and adjust it. No manual modifications
               were done on the generated word forms and lemmas. Our fully automatic
               procedure has the advantage that whenever new versions of the
               source lexica are available, a new version of ColLex.EN can be
               automatically generated with low effort.},

               context of authoring image-related hypertexts by example of the
               museum information system WikiNect. To this end, a first implementation
               of gestural writing based on image schemata is provided (Lakoff
               in Women, fire, and dangerous things: what categories reveal about
               the mind. University of Chicago Press, Chicago, 1987). Gestural
               writing is defined as a sort of coding in which propositions are
               only expressed by means of gestures. In this respect, it is shown
               that image schemata allow for bridging between natural language
               predicates and gestural manifestations. Further, it is demonstrated
               that gestural writing primarily focuses on the perceptual level
               of image descriptions (Hollink et al. in Int J Hum Comput Stud
               61(5):601–626, 2004). By exploring the metaphorical potential
               of image schemata, it is finally illustrated how to extend the
               expressiveness of gestural writing in order to reach the conceptual
               level of image descriptions. In this context, the paper paves
               the way for implementing museum information systems like WikiNect
               as systems of kinetic hypertext authoring based on full-fledged
               gestural writing.},

               Firstly, it is argued that symbol grounding in general has to
               be instrinsic. Current approaches in this context, however, are
               limited to a certain kind of expression that can be grounded in
               this way. Secondly, we identify three requirements for conversational
               grounding, the process leading to mutual understanding. Finally,
               we sketch a test case for symbol grounding in the form of the
               philosophical grounding problem that involves the use of modal
               language. Together, the three grounding problems provide a grid
               that allows us to assess ADCs’ dialogical performances and to
               pinpoint future developments on these grounds.},

               simulation studies on language evolution and the establishment

               the creation of linguistic categories, most notably for color
               terms. We recap the functional principle of NGs and the latter
               Categorization Games (CGs) and evaluate them in the light of semantic
               data of linguistic categorization outside the domain of colors.
               This comparison reveals two specifics of the CG paradigm: Firstly,
               the emerging categories draw basically on the predefined topology
               of the learning domain. Secondly, the kind of categories that
               can be learnt in CGs is bound to context-independent intersective
               categories. This suggests that the NG and the CG focus on a special
               aspect of natural language categorization, which disregards context-sensitive
               categories used in a non-compositional manner.},

               Time-Aligned Network) series. TiTAN series capture the formation
               and structure of dialog lexica in terms of serialized graph representations.
               The dynamic update of TiTAN series is driven by the dialog-inherent
               timing of turn-taking. The model provides a link between neural,
               connectionist underpinnings of dialog lexica on the one hand and
               observable symbolic behavior on the other. On the neural side,
               priming and spreading activation are modeled in terms of TiTAN
               networking. On the symbolic side, TiTAN series account for cognitive
               alignment in terms of the structural coupling of the linguistic
               representations of dialog partners. This structural stance allows
               us to apply TiTAN in machine learning of data of dialogical alignment.
               In previous studies, it has been shown that aligned dialogs can
               be distinguished from non-aligned ones by means of TiTAN -based
               modeling. Now, we simultaneously apply this model to two types
               of dialog: task-oriented, experimentally controlled dialogs on
               the one hand and more spontaneous, direction giving dialogs on
               the other. We ask whether it is possible to separate aligned dialogs
               from non-aligned ones in a type-crossing way. Starting from a
               recent experiment (Mehler, Lücking, \& Menke, 2011a), we show
               that such a type-crossing classification is indeed possible. This
               hints at a structural fingerprint left by alignment in networks
               of linguistic items that are routinely co-activated during conversation.},

               allows museum visitors to give on-site feedback about exhibitions.
               To this end, WikiNect integrates three approaches to Human-Computer
               Interaction (HCI): games with a purpose, wiki-based collaborative
               writing and kinetic text-technologies. Our aim is to develop kinetic
               technologies as a new paradigm of HCI. They dispense with classical
               interfaces (e.g., keyboards) in that they build on non-contact
               modes of communication like gestures or facial expressions as
               input displays. In this paper, we introduce the notion of gestural
               writing as a kinetic text-technology that underlies WikiNect to
               enable museum visitors to communicate their feedback. The basic
               idea is to explore sequences of gestures that share the semantic
               expressivity of verbally manifested speech acts. Our task is to
               identify such gestures that are learnable on-site in the usage
               scenario of WikiNect. This is done by referring to so-called transient
               gestures as part of multimodal ensembles, which are candidate
               gestures of the desired functionality.},

               information theory, we show that there is an information transmission

               merely knowing its lexical affiliate – in line with the notion
               of the primacy of language. Thus, there is evidence for a one-way

               alignment and underlies the constitution of multimodal ensembles.},

               metadata of scholarly publications is of utmost interest. One
               of the most prevalent approaches for metadata exchange is the
               XML-based Open Archive Initiative (OAI) Protocol for Metadata
               Harvesting (OAI-PMH). However, due to its loose requirements regarding
               metadata content there is no strict standard for consistent subject
               indexing specified, which is furthermore needed in the digital
               library domain. This contribution addresses the problem of automatic
               enhancement of OAI metadata by means of the most widely used universal
               classification schemes in libraries—the Dewey Decimal Classification
               (DDC). To be more specific, we automatically classify scientific
               documents according to the DDC taxonomy within three levels using
               a machine learning-based classifier that relies solely on OAI
               metadata records as the document representation. The results show
               an asymmetric distribution of documents across the hierarchical
               structure of the DDC taxonomy and issues of data sparseness. However,
               the performance of the classifier shows promising results on all
               three levels of the DDC.},

               networks serves as input to the classification algorithm. The

               In addition, we test two alternative approaches to automatic language

               typological indices. All three methods show good results in identifying

               many institutional and individual users. Formulas for approximately
               measuring text readability have a long tradition. Usually, they
               exploit surface-oriented indicators like sentence length, word
               length, word frequency, etc. However, in many cases, this information
               is not adequate to realistically approximate the cognitive difficulties
               a person can have to understand a text. Therefore we use deep
               syntactic and semantic indicators in addition. The syntactic information
               is represented by a dependency tree, the semantic information
               by a semantic network. Both representations are automatically
               generated by a deep syntactico-semantic analysis. A global readability
               score is determined by applying a nearest neighbor algorithm on
               3,000 ratings of 300 test persons. The evaluation showed that
               the deep syntactic and semantic indicators lead to promising results
               comparable to the best surface-based indicators. The combination
               of deep and shallow indicators leads to an improvement over shallow
               indicators alone. Finally, a graphical user interface was developed
               which highlights difficult passages, depending on the individual
               indicator values, and displays a global readability score.},

               in the area of complex network theory. This is done by analyzing
               social ontologies as a new resource for automatic language classification.
               Our method is to solely explore structural features of social
               ontologies in order to predict family resemblances of languages
               used by the corresponding communities to build these ontologies.
               This approach is based on a reformulation of the Sapir-Whorf Hypothesis
               in terms of distributed cognition. Starting from a corpus of 160
               Wikipedia-based social ontologies, we test our variant of the
               Sapir-Whorf Hypothesis by several experiments, and find out that
               we outperform the corresponding baselines. All in all, the article
               develops an approach to classify linguistic networks of tens of
               thousands of vertices by exploring a small range of mathematically
               well-established topological indices.},

               frameworks that are concerned with the development of linguistic
               categories within a population of language users. Although these
               studies mostly emphasize that their models are abstract, the paradigm
               categorization domain is preferably that of colors. In this paper,
               the authors argue that color adjectives are special predicates
               in both linguistic and metaphysical terms: semantically, they
               are intersective predicates, metaphysically, color properties
               can be empirically reduced onto purely physical properties. The
               restriction of categorization simulations to the color paradigm
               systematically leads to ignoring two ubiquitous features of natural
               language predicates, namely relativity and context-dependency.
               Therefore, the models for simulation models of linguistic categories
               are not able to capture the formation of categories like perspective-dependent
               predicates ‘left’ and ‘right’, subsective predicates like ‘small’
               and ‘big’, or predicates that make reference to abstract objects
               like ‘I prefer this kind of situation’. The authors develop a
               three-dimensional grid of ascending complexity that is partitioned
               according to the semiotic triangle. They also develop a conceptual
               model in the form of a decision grid by means of which the complexity
               level of simulation models of linguistic categorization can be
               assessed in linguistic terms.},

               die Medienwissenschaft darstellt, resultiert nicht nur aus der
               ungeheuren Beschleunigung des Medienwandels. Die Herausforderung
               stellt sich auch mit der Frage, welches die neuen Formen und Strukturen
               sind, die aus dem Wandel der Medien hervorgehen. R{\"u}ckt man
               diese Frage in den Fokus der {\"U}berlegungen, kommen erstens
               Entwicklungen im Wechsel von Massenmedien zu neuen, „interaktiven``
               Medien in den Blick. Dies betrifft den Wandel von den alten Medien
               in Form von Einwegkommunikation zu den neuen Medien in Form von
               Netzkommunikation. Dieser Wandel wurde in zahlreichen Analysen
               als eine Revolution beschrieben: Im Unterschied zur einseitigen,
               r{\"u}ckkopplungsarmen Kommunikationsform der Massenmedien sollen
               neue, computergest{\"u}tzte Formen der Medienkommunikation „interaktiv``
               sein, d.h. gesteigerte R{\"u}ckkopplungs- und Eingriffsm{\"o}glichkeiten
               f{\"u}r die Adressaten und Nutzer bieten. Sozialwissenschaftlich
               bedeutsam ist dabei die Einsch{\"a}tzung der Qualit{\"a}t und
               des Umfangs dieser neuen M{\"o}glichkeiten und Leistungen. Denn
               bislang bedeutete Medienwandel im Kern eine zunehmende Ausdifferenzierung
               alter und neuer Medien mit je spezifischen Leistungen, d.h. neue
               Medien ersetzen die {\"a}lteren nicht, sondern sie erg{\"a}nzen
               und erweitern sie. Allerdings wird im Zuge des aktuellen Medienwandels
               immer deutlicher, dass die neuen Medien durchaus imstande sind,
               die Leistungen massenmedialer Verbreitung von Kommunikation zu
               {\"u}bernehmen. Stehen wir also, wie das schon seit l{\"a}ngerem
               k{\"u}hn vorhergesagt wird, vor der Etablierung eines Universalmediums,
               das in der Lage ist, die Formen und Funktionen anderer Medien

               linguistically, that is, they align interpersonally. In this article,
               we develop a framework for modeling interpersonal alignment in
               terms of the structural similarity of the interlocutors’ dialog
               lexica. This is done by means of so-called two-layer time-aligned
               network series, that is, a time-adjusted graph model. The graph
               model is partitioned into two layers, so that the interlocutors’
               lexica are captured as subgraphs of an encompassing dialog graph.
               Each constituent network of the series is updated utterance-wise.
               Thus, both the inherent bipartition of dyadic conversations and
               their gradual development are modeled. The notion of alignment
               is then operationalized within a quantitative model of structure
               formation based on the mutual information of the subgraphs that
               represent the interlocutor’s dialog lexica. By adapting and further
               developing several models of complex network theory, we show that
               dialog lexica evolve as a novel class of graphs that have not
               been considered before in the area of complex (linguistic) networks.
               Additionally, we show that our framework allows for classifying
               dialogs according to their alignment status. To the best of our
               knowledge, this is the first approach to measuring alignment in
               communication that explores the similarities of graph-like cognitive
               representations.},

               Markovian Trees (MSMTs). The idea behind MSMTs is to provide spanning
               trees that minimize the costs of edge traversals in a Markovian
               manner, that is, in terms of the path starting with the root of
               the tree and ending at the vertex under consideration. In a second
               part, the chapter generalizes this class of spanning trees in
               order to allow for damped Markovian effects in the course of spanning.
               These two effects, (1) the sensitivity to the contexts generated
               by consecutive edges and (2) the decreasing impact of more antecedent
               (or 'weakly remembered') vertices, are well known in cognitive
               modeling [6, 10, 21, 23]. In this sense, the chapter can also
               be read as an effort to introduce a graph model to support the
               simulation of cognitive systems. Note that MSMTs are not to be
               confused with branching Markov chains or Markov trees [20] as
               we focus on generating spanning trees from given weighted undirected
               networks.},

               utilizes a social ontology to create an alignment of documents
               within a social network. Comprised category information is used
               to compute a topic generalization. We propose a feature-frequency-based
               method for measuring semantic relatedness which is needed in order
               to reduce the number of document features for the task of topic
               labelling. This method is evaluated against multiple human judgement
               experiments comprising two languages and three different resources.
               Overall the results show that social ontologies provide a rich
               source of terminological knowledge. The performance of the semantic
               relatedness measure with correlation values of up to .77 are quite
               promising. Results on the topic labelling experiment show, with
               an accuracy of up to .79, that our approach can be a valuable
               method for various NLP applications.},

  abstract  = {Purpose: We present a topic classification model using the Dewey
               Decimal Classification (DDC) as the target scheme. This is done
               by exploring metadata as provided by the Open Archives Initiative
               (OAI) to derive document snippets as minimal document representations.
               The reason is to reduce the effort of document processing in digital
               libraries. Further, we perform feature selection and extension
               by means of social ontologies and related web-based lexical resources.
               This is done to provide reliable topic-related classifications
               while circumventing the problem of data sparseness. Finally, we
               evaluate our model by means of two language-specific corpora.
               This paper bridges digital libraries on the one hand and computational
               linguistics on the other. The aim is to make accessible computational
               linguistic methods to provide thematic classifications in digital
               libraries based on closed topic models as the DDC. Design/methodology/approach:
               text classification, text-technology, computational linguistics,
               computational semantics, social semantics. Findings: We show that
               SVM-based classifiers perform best by exploring certain selections
               of OAI document metadata. Research limitations/implications: The
               findings show that it is necessary to further develop SVM-based
               DDC-classifiers by using larger training sets possibly for more
               than two languages in order to get better F-measure values. Practical
               implications: We can show that DDC-classifications come into reach
               which primarily explore OAI metadata. Originality/value: We provide
               algorithmic and formal-mathematical information how to build DDC-classifiers
               for digital libraries.},

               to describe in their entirety, but we plan for the finished reference
               corpus to contain multi-level tags of the respective genre or
               genres a web document or a website instantiates. As the construction
               of such a corpus is by no means a trivial task, we discuss several
               alternatives that are, for the time being, mostly based on existing
               collections. Furthermore, we discuss a shared set of genre categories
               and a multi-purpose tool as two additional prerequisites for a

               large complex networks by example of wiki graphs. By means of
               this framework we reliably measure the similarity of document,
               agent, and word networks by solely regarding their topology. In
               doing so, the article departs from classical approaches to complex
               network theory which focuses on topological characteristics in
               order to check their small world property. This does not only
               include characteristics that have been studied in complex network
               theory, but also some of those which were invented in social network
               analysis and hypertext theory. We show that network classifications
               come into reach which go beyond the hypertext structures traditionally
               analyzed in web mining. The reason is that we focus on networks
               as a whole as units to be classified—above the level of websites
               and their constitutive pages. As a consequence, we bridge classical
               approaches to text and web mining on the one hand and complex
               network theory on the other hand. Last but not least, this approach
               also provides a framework for quantifying the linguistic notion
               of intertextuality.},

               in quantitative text semantics as an alternative to the bag-of-features
               approach. The variant includes effects of context-sensitive interpretation
               as well as processes of meaning constitution and change in the
               sense of usage-based semantics. Its starting point is a combination
               of semantic space modeling and text structure analysis. The principle
               is implemented by means of a hierarchical constraint satisfaction
               process which utilizes the notion of hierarchical text structure
               superimposed by graph-inducing coherence relations. The major
               contribution of the chapter is a conceptualization and formalization
               of the principle of compositionality in terms of semantic spaces
               which tackles some well known deficits of existing approaches.
               In particular this relates to the missing linguistic interpretability
               of statistical meaning representations.},

               structure or layout (Brinker, 1992; Bateman et al., 2001; Joachims,
               2002; Power et al., 2003). These reference points do not open
               necessarily orthogonal perspectives on text classification. As
               part of explorative data analysis, text classification aims at
               automatically dividing sets of textual objects into classes of
               maximum internal homogeneity and external heterogeneity. This
               paper deals with classifying texts into text types whose instances
               serve more or less homogeneous functions. Other than mainstream
               approaches, which rely on the vector space model (Sebastiani,
               2002) or some of its descendants (Baeza-Yates and Ribeiro-Neto,
               1999) and, thus, on content-related lexical features, we solely
               refer to structural differentiae. That is, we explore patterns
               of text structure as determinants of class membership. Our starting
               point are tree-like text representations which induce feature
               vectors and tree kernels. These kernels are utilized in supervised
               learning based on cross-validation as a method of model selection
               (Hastie et al., 2001) by example of a corpus of press communication.
               For a subset of categories we show that classification can be
               performed very well by structural differentia only.},

  abstract  = {Gegenstand des folgenden Aufsatzes ist der konnotative Aspekt
               der Bedeutungen von Texten. Den Ausgangspunkt der {\"U}berlegungen
               zur Konnotation des Textes bildet die Auffassung, wonach Wort-
               und Textbedeutungskonstitution Ergebnis eines zirkul{\"a}ren Prozesses
               sind, der für die Emergenz einer Hierarchie ineinander geschachtelter
               Spracheinheiten verantwortlich zeichnet. Der Proze{\ss} der Zeichenartikulation
               erfolgt entlang dieser Ebenen und erzeugt durch Verbindung von
               (konnotativer) Inhalts- und Ausdrucksseite auf Textebene das Textzeichen.
               Im Gegensatz zu einer strikten Interpretation des Fregeschen Kompositionalit{\"a}tsprinzips,
               derzufolge die Bedeutungen sprachlicher Einheiten als fixierte,
               kontextfreie Grö{\ss}en vorauszusetzen sind, behandelt der vorliegende
               Ansatz bereits die lexikalische Bedeutung als Grö{\ss}e, die in
               Abh{\"a}ngigkeit von ihrem Kontext variieren kann. Aus semiotischer
               Perspektive ist es vor allem der Gestaltcharakter, welcher die
               konnotative Textbedeutung einer Anwendung des FregePrinzips entzieht.
               Anders ausgedrückt: Die konnotative Bedeutung eines Textes ist
               keineswegs in eine Struktur 'atomarer' Repr{\"a}sentationen zerlegbar.
               Die hierarchische Organisation von Texten erweist sich insofern
               als komplex, als ihre Bedeutungen aus einem zirkul{\"a}ren Proze{\ss}
               resultieren, der best{\"a}tigend und/oder ver{\"a}ndernd auf die
               Bedeutungen der Textkonstituenten einwirkt. Diese Zirkularit{\"a}t
               bedingt, da{\ss} Texte nicht nur als Orte der Manifestation von
               Wortbedeutungsstrukturen anzusehen sind, sondern zugleich als
               Ausgangspunkte für die Modifikation und Emergenz solcher Strukturen
               dienen. Im folgenden wird unter Rekurs auf den Kopenhagener Strukturalismus
               ein Modell der konnotativen Bedeutung von Texten entwickelt, das
               sich unter anderem an dem glossematischen Begriff der Konstante
               orientiert. Die Formalisierung des Modells erfolgt mit Hilfe des
               Konzeptes der unscharfen Menge. Zu diesem Zweck werden die unscharfen
               Verwendungsregularit{\"a}ten von Wörtern auf der Basis eines zweistufigen
               Verfahrens analysiert, welches die syntagmatischen und paradigmatischen
               Regularit{\"a}ten des Wortgebrauches berücksichtigt. Die Rolle
               der Satzebene innerhalb des Prozesses der konnotativen Textbedeutungskonstitution
               wird angedeutet. Abschlie{\ss}end erfolgt eine Exemplifizierung
               des Algorithmus anhand der automatischen Analyse eines Textcorpus.},

               trees are ordered trees in which every node might be labeled by
               a vector of attributes including its XML tag and the textual content.
               We describe five new kernels suitable for such structures: a kernel
               based on predefined structural features, a tree kernel derived
               from the well-known parse tree kernel, the set tree kernel that
               allows permutations of children, the string tree kernel being
               an extension of the so-called partial tree kernel, and the soft
               tree kernel as a more efficient alternative. We evaluate the kernels
               experimentally on a corpus containing the DOM trees of newspaper
               articles and on the well-known SUSANNE corpus.},

               denote text types whose textual instances serve more or less homogeneous
               functions. Other than mainstream approaches to text classification,
               which rely on the vector space model [30] or some of its descendants
               [2] and, thus, on content-related lexical features, we solely
               refer to structural differentiae, that is, to patterns of text
               structure as determinants of class membership. Further, we suppose
               that text types span a type hierarchy based on the type-subtype
               relation [31]. Thus, although we admit that class membership is
               fuzzy so that overlapping classes are inevitable, we suppose a
               non-overlapping type system structured into a rooted tree – whether
               solely based on functional or additional on, e.g., content- or
               mediabased criteria [1]. What regards criteria of goodness of
               classification, we perform a classical supervised categorization
               experiment [30] based on cross-validation as a method of model
               selection [11]. That is, we perform a categorization experiment
               in which for all training and test cases class membership is known
               ex ante. In summary, we perform a supervised experiment of text
               classification in order to learn functionally grounded text types
               where membership to these types is solely based on structural
               criteria.},

               notion of a naming game (Steels, 1996). The simulation model integrates
               a small world-like agent community which restricts agent communication.

               to simulate terminological alignment based on lexical priming.

               Established approaches have to be enhanced and new methods be
               developed in order to tackle the problem of finding and organising
               relevant information. It has often been motivated that semantic
               classifications of input documents help solving this task. But
               while approaches of supervised text categorisation perform quite
               well on genres found in written text, newly evolved genres on
               the web are much more demanding. In order to successfully develop
               approaches to web mining, respective corpora are needed. However,
               the composition of genre- or domain-specific web corpora is still
               an unsolved problem. It is time consuming to build large corpora
               of good quality because web pages typically lack reliable meta
               information. Wikipedia along with similar approaches of collaborative
               text production offers a way out of this dilemma. We examine how
               social tagging, as supported by the MediaWiki software, can be
               utilised as a source of corpus building. Further, we describe
               a representation format for social ontologies and present the
               Wikipedia Category Explorer, a tool which supports categorical
               views to browse through the Wikipedia and to construct domain
               specific corpora for machine learning.},

               of documents online the adaptation of text categorization to web
               units has recently been pushed. The aim is to utilize categories
               of web sites and pages as an additional retrieval criterion. In
               this context, the bag-of-words model has been utilized just as
               HTML tags and link structures. In spite of promising results this
               adaptation stays in the framework of IR specific models since
               it neglects the content-based structuring inherent to hypertext
               units. This paper approaches hypertext modelling from the perspective
               of graph-theory. It presents an XML-based format for representing
               websites as hypergraphs. These hypergraphs are used to shed light
               on the relation of hypertext structure types and their web-based
               instances. We place emphasis on two characteristics of this relation:
               In terms of realizational ambiguity we speak of functional equivalents
               to the manifestation of the same structure type. In terms of polymorphism
               we speak of a single web unit which manifests different structure
               types. It is shown that polymorphism is a prevalent characteristic
               of web-based units. This is done by means of a categorization
               experiment which analyses a corpus of hypergraphs representing
               the structure and content of pages of conference websites. On
               this background we plead for a revision of text representation
               models by means of hypergraphs which are sensitive to the manifold
               structuring of web documents.},

               document structures are based on, e.g., tag measures, path metrics
               and tree measures in terms of their DOM-Trees. Other methods measures
               the similarity in the framework of the well known vector space
               model. In contrast to these we present a new approach to measuring
               the structural similarity of web-based documents represented by
               so called generalized trees which are more general than DOM-Trees
               which represent only directed rooted trees. We will design a new
               similarity measure for graphs representing web-based hypertext
               structures. Our similarity measure is mainly based on a novel
               representation of a graph as strings of linear integers, whose
               components represent structural properties of the graph. The similarity
               of two graphs is then defined as the optimal alignment of the
               underlying property strings. In this paper we apply the well known
               technique of sequence alignments to solve a novel and challenging
               problem: Measuring the structural similarity of generalized trees.
               More precisely, we first transform our graphs considered as high
               dimensional objects in linear structures. Then we derive similarity
               values from the alignments of the property strings in order to
               measure the structural similarity of generalized trees. Hence,
               we transform a graph similarity problem to a string similarity
               problem. We demonstrate that our similarity measure captures important
               structural information by applying it to two different test sets
               consisting of graphs representing web-based documents.},

               category labels to hypertext units. Comparable to text categorization
               it stays in the area of function learning based on the bag-of-features
               approach. This scenario faces the problem of a many-to-many relation
               between websites and their hidden logical document structure.
               The paper argues that this relation is a prevalent characteristic
               which interferes any effort of applying the classical apparatus
               of categorization to web genres. This is confirmed by a threefold
               experiment in hypertext categorization. In order to outline a
               solution to this problem, the paper sketches an alternative method
               of unsupervised learning which aims at bridging the gap between
               statistical and structural pattern recognition (Bunke et al. 2001)

  abstract  = {Beitr{\"a}ge zum Thema Text Mining beginnen vielfach mit dem Hinweis
               auf die enorme Zunahme online verfügbarer Dokumente, ob nun im
               Internet oder in Intranets (Losiewicz et al. 2000; Merkl 2000;
               Feldman 2001; Mehler 2001; Joachims \& Leopold 2002). Der hiermit
               einhergehenden „Informationsflut“ wird das Ungenügen des Information
               Retrieval (IR) bzw. seiner g{\"a}ngigen Verfahren der Informationsaufbereitung
               und Informationserschlie{\ss}ung gegenübergestellt. Es wird bem{\"a}ngelt,
               dass sich das IR weitgehend darin erschöpft, Teilmengen von Textkollektionen
               auf Suchanfragen hin aufzufinden und in der Regel blo{\ss} listenförmig
               anzuordnen. Das auf diese Weise dargestellte Spannungsverh{\"a}ltnis
               von Informationsexplosion und Defiziten bestehender IR-Verfahren
               bildet den Hintergrund für die Entwicklung von Verfahren zur automatischen
               Verarbeitung textueller Einheiten, die sich st{\"a}rker an den
               Anforderungen von Informationssuchenden orientieren. Anders ausgedrückt:
               Mit der Einführung der Neuen Medien w{\"a}chst die Bedeutung digitalisierter
               Dokumente als Prim{\"a}rmedium für die Verarbeitung, Verbreitung
               und Verwaltung von Information in öffentlichen und betrieblichen
               Organisationen. Dabei steht wegen der Menge zu verarbeitender
               Einheiten die Alternative einer intellektuellen Dokumenterschlie{\ss}ung
               nicht zur Verfügung. Andererseits wachsen die Anforderung an eine
               automatische Textanalyse, der das klassische IR nicht gerecht
               wird. Der Mehrzahl der hiervon betroffenen textuellen Einheiten
               fehlt die explizite Strukturiertheit formaler Datenstrukturen.
               Vielmehr weisen sie je nach Text- bzw. Dokumenttyp ganz unterschiedliche
               Strukturierungsgrade auf. Dabei korreliert die Flexibilit{\"a}t
               der Organisationsziele negativ mit dem Grad an explizierter Strukturiertheit
               und positiv mit der Anzahl jener Texte und Texttypen (E-Mails,
               Memos, Expertisen, technische Dokumentationen etc.), die im Zuge
               ihrer Realisierung produziert bzw. rezipiert werden. Vor diesem
               Hintergrund entsteht ein Bedarf an Texttechnologien, die ihren
               Benutzern nicht nur „intelligente“ Schnittstellen zur Textrezeption
               anbieten, sondern zugleich auf inhaltsorientierte Textanalysen
               zielen, um auf diese Weise aufgabenrelevante Daten explorieren
               und kontextsensitiv aufbereiten zu helfen. Das Text Mining ist
               mit dem Versprechen verbunden, eine solche Technologie darzustellen
               bzw. sich als solche zu entwickeln. Dieser einheitlichen Problembeschreibung
               stehen konkurrierende Textmining-Spezifikationen gegenüber, was
               bereits die Vielfalt der Namensgebungen verdeutlicht. So finden
               sich neben der Bezeichnung Text Mining (Joachims \& Leopold 2002;
               Tan 1999) die Alternativen • Text Data Mining (Hearst 1999b; Merkl
               2000), • Textual Data Mining (Losiewicz et al. 2000), • Text Knowledge
               Engineering (Hahn \& Schnattinger 1998), Knowledge Discovery in
               Texts (Kodratoff 1999) oder Knowledge Discovery in Textual Databases
               (Feldman \& Dagan 1995). Dabei l{\"a}sst bereits die Namensgebung
               erkennen, dass es sich um Analogiebildungen zu dem (nur unwesentlich
               {\"a}lteren) Forschungsgebiet des Data Mining (DM; als Bestandteil
               des Knowledge Discovery in Databases – KDD) handelt. Diese Namensvielfalt
               findet ihre Entsprechung in widerstreitenden Aufgabenzuweisungen.
               So setzt beispielsweise Sebastiani (2002) Informationsextraktion
               und Text Mining weitgehend gleich, wobei er eine Schnittmenge
               zwischen Text Mining und Textkategorisierung ausmacht (siehe auch
               Dörre et al. 1999). Demgegenüber betrachten Kosala \& Blockeel
               (2000) Informationsextraktion und Textkategorisierung lediglich
               als Teilbereiche des ihrer Ansicht nach umfassenderen Text Mining,
               w{\"a}hrend Hearst (1999a) im Gegensatz hierzu Informationsextraktion
               und Textkategorisierung explizit aus dem Bereich des explorativen
               Text Mining ausschlie{\ss}t.},

               analyses of textual units have substantial need for large corpora.
               More specifically, genre or register specific corpora are needed
               which allow studying variations in language use. Along with the
               incredible growth of the internet, the web became an important
               source of linguistic data. Of course, web corpora face the same
               problem of acquiring genre specific corpora. Amongst other things,
               web mining is a framework of methods for automatically assigning
               category labels to web units and thus may be seen as a solution
               to this corpus acquisition problem as far as genre categories
               are applied. The paper argues that this approach is faced with
               the problem of a many-to-many relation between expression units
               on the one hand and content or function units on the other hand.
               A quantitative study is performed which supports the argumentation
               that functions of web-based communication are very often concentrated
               on single web pages and thus interfere any effort of directly
               applying the classical apparatus of categorization on web page
               level. The paper outlines a two-level algorithm as an alternative
               approach to category assignment which is sensitive to genre specific
               structures and thus may be used to tackle the problem of acquiring
               genre specific corpora.},

  abstract  = {Due to the tremendous amount of information provided by the World
               Wide Web (WWW) developing methods for mining the structure of
               web-based documents is of considerable interest. In this paper
               we present a similarity measure for graphs representing web-based
               hypertext structures. Our similarity measure is mainly based on
               a novel representation of a graph as linear integer strings, whose
               components represent structural properties of the graph. The similarity
               of two graphs is then defined as the optimal alignment of the
               underlying property strings. In this paper we apply the well known
               technique of sequence alignments for solving a novel and challenging
               problem: Measuring the structural similarity of generalized trees.
               In other words: We first transform our graphs considered as high
               dimensional objects in linear structures. Then we derive similarity
               values from the alignments of the property strings in order to
               measure the structural similarity of generalized trees. Hence,
               we transform a graph similarity problem to a string similarity
               problem for developing a efficient graph similarity measure. We
               demonstrate that our similarity measure captures important structural
               information by applying it to two different test sets consisting
               of graphs representing web-based document structures.},

               Webpages zum Zwecke ihrer inhaltsorientierten Filterung kategorisiert
               werden können. Diese Studie untersucht zwei Ph{\"a}nomene, welche
               die Bedingung der Möglichkeit einer solchen Kategorisierung betreffen
               (siehe [6]): Mit dem Begriff der funktionalen Aquivalenz beziehen
               wir uns auf das Ph{\"a}nomen, dass dieselbe Funktions- oder Inhaltskategorie
               durch völlig verschiedene Bausteine Web-basierter Dokumente manifestiert
               werden kann. Mit dem Begriff des Polymorphie beziehen wir uns
               auf das Ph{\"a}nomen, dass dasselbe Dokument zugleich mehrere
               Funktions- oder Inhaltskategorien manifestieren kann. Die zentrale
               Hypothese lautet, dass beide Ph{\"a}nomene für Web-basierte Hypertextstrukturen
               charakteristisch sind. Ist dies der Fall, so kann die automatische
               Kategorisierung von Hypertexten [2, 10] nicht mehr als eindeutige
               Zuordnung verstanden werden, bei der einem Dokument genau eine
               Kategorie zugeordnet wird. In diesem Sinne thematisiert das Papier

               von Hyperlinks, wie sie im WWW für die Informationssuche bereitstehen.
               Dabei steht die Frage im Vordergrund, auf welche Weise bestehende
               Verfahren suchrelevante Dokumente bestimmen und von diesen aus
               inhaltsverwandte Dokumente verlinken. Dieser Gegenstand verbindet
               den Bereich des klassischen Information Retrievals (IR) mit einem
               Anwendungsgebiet, das in der Wissenschaftskommunikation unter
               dem Stichwort der digitalen Bibliothek unter Nutzbarmachung des
               Hyperlink-basierten Browsings firmiert. Ein Beispiel hierfür bildet
               die digitale Bibliothek CiteSeer (Lawrence et al. 1999), welche
               das Boolesche Retrieval dadurch erweitert, dass ausgehend von
               Treffern einer Suche jene Dokumente per Link angesteuert werden
               können, welche die aufgefundenen Dokumente zitieren oder von diesen
               zitiert werden. CiteSeer ist also ein System, welches das Schlagwort-basierte
               Querying im Rahmen des klassischen IRs mit dem Hypertext-basierten
               Browsing von Zitaten verknüpft, und zwar zu dem Zweck, die Suche
               wissenschaftlicher Dokumente zu erleichtern. Darüber hinaus verwendet
               es die unter dem Stichwort des Vektorraummodells bekannt gewordene
               Technologie für den wortbasierten Vergleich von Texten. Der Beitrag
               setzt an dieser Stelle an. Er argumentiert, dass Verfahren bereitstehen,
               welche die Anforderung nach inhaltsorientiertem Retrieval mit
               dem inhaltsorientierten Browsing verbinden, mit der Forderung
               also, dass Hyperlinks, die E-Texte als digitalisierte Versionen
               von (wissenschaftlichen) Dokumenten verknüpfen (Storrer 2002),
               Inhalts- und nicht nur Zitat-basiert sind.},

               learning from texts. It requires a format which allows to interrelate

               are used as a format for modeling similarities of natural language
               texts represented as vectors. They prove to be efficient in divergent
               areas, as information retrieval (Dumais 1995), computational psychology
               (Landauer, Dumais 1997), and computational linguistics (Rieger
               1995; Mehler 1998). In order to group semantically similar texts,
               cluster analysis is used. A central problem of this method relates
               to the difficulty to name clusters, whereas lists neglect the
               polyhierarchical structure of semantic spaces. This paper introduces
               the concept of cohesion tree as an alternative tool for exploring
               similarity relations of texts represented in high dimensional
               spaces. Cohesion trees allow the perspective evaluation of numerically
               represented text similarities. They depart from minimal spanning
               trees (MST) by context-sensitively optimizing path costs. This
               central property underlies the linguistic interpretation of cohesion
               trees: instead of manifesting context-free associations, they
               model context priming effects.},

  abstract  = {On the background of rising Intranet applications the automatic
               generation of adaptable, context-sensitive hypertexts becomes
               more and more important [El-Beltagy et al., 2001]. This observation
               contradicts the literature on hypertext authoring, where Information
               Retrieval techniques prevail, which disregard any linguistic and
               context-theoretical underpinning. As a consequence, resulting
               hypertexts do not manifest those schematic structures, which are
               constitutive for the emergence of text types and the context-mediated
               understanding of their instances, i.e. natural language texts.
               This paper utilizes Systemic Functional Linguistics (SFL) and
               its context model as a theoretical basis of hypertext authoring.
               So called Systemic Functional Hypertexts (SFHT) are proposed,
               which refer to a stratified context layer as the proper source
               of text linkage. The purpose of this paper is twofold: First,
               hypertexts are reconstructed from a linguistic point of view as
               a kind of supersign, whose constituents are natural language texts
               and whose structuring is due to intra- and intertextual coherence
               relations and their context-sensitive interpretation. Second,
               the paper prepares a formal notion of SFHTs as a first step towards
               operationalization of fundamental text linguistic concepts. On
               this background, SFHTs serve to overcome the theoretical poverty
               of many approaches to link generation.},

  abstract  = {The significance of natural language texts as the prime information
               structure for the management and dissemination of knowledge in
               organisations is still increasing. Making relevant documents available
               depending on varying tasks in different contexts is of primary
               importance for any efficient task completion. Implementing this
               demand requires the content based processing of texts, which enables
               to reconstruct or, if necessary, to explore the relationship of
               task, context and document. Text mining is a technology that is
               suitable for solving problems of this kind. In the following,
               semiotic aspects of text mining are investigated. Based on the
               primary object of text mining - natural language lexis - the specific
               complexity of this class of signs is outlined and requirements
               for the implementation of text mining procedures are derived.
               This is done with reference to text linkage introduced as a special
               task in text mining. Text linkage refers to the exploration of
               implicit, content based relations of texts (and their annotation
               as typed links in corpora possibly organised as hypertexts). In
               this context, the term systemic functional hypertext is introduced,
               which distinguishes genre and register layers for the management
               of links in a poly-level hypertext system},

               handelt sich dabei um eine rein webbasierte Umgebung für die texttechnologische
               Arbeit mit Korpora, welche von der standardisierten Repr{\"a}sentation
               textueller Einheiten über deren computerlinguistische Vorverarbeitung
               bis hin zu Text Mining–Funktionalit{\"a}ten eine gro{\ss}e Zahl
               von Werkzeugen integriert. Diese Integrationsleistung betrifft
               neben den Textkorpora und den hierauf operierenden texttechnologischen
               Werkzeugen auch die je zum Einsatz kommenden lexikalischen Ressourcen.
               Aus dem Blickwinkel der geisteswissenschaftlichen Fachinformatik
               gesprochen fokussiert der Desktop somit darauf, eine Vielzahl
               heterogener sprachlicher Ressourcen mit grundlegenden texttechnologischen
               Methoden zu integrieren, und zwar so, dass das Integrationsresultat
               auch in den H{\"a}nden von Nicht–Texttechnologen handhabbar bleibt.
               Wir exemplifizieren diese Handhabung an einem Beispiel aus der
               historischen Semantik, und damit an einem Bereich, der erst in
               jüngerer Zeit durch die Texttechnologie erschlossen wird.},
