  abstract  = {The constitution of multiple documents has so far been studied
               essentially as a process in which a single learner consults a
               number (of segments) of different documents in the context of
               the task at hand in order to construct a mental model for the
               purpose of completing the task. As a result of this research focus,
               the constitution of multiple documents appears predominantly as
               a monomodal, non-interactive process in which mainly textual units
               are studied, supplemented by images, text-image relations and
               comparable artifacts. This approach is reflected in the contextual
               fixity of the research design, in which the learners under study
               search for information using suitably equipped computers. If,
               on the other hand, we consider the openness of multi-agent learning
               situations, this scenario lacks the aspects of interactivity,
               contextual openness and, above all, the multimodality of information
               objects, information processing and information exchange. This
               is where the chapter comes in. It describes Va.Si.Li-Lab as an
               instrument for multimodal measurement for studying and modeling
               multiple documents in the context of interactive learning in a
               multi-agent environment. To this end, the chapter places Va.Si.Li-Lab
               in the spectrum of evolutionary approaches that vary the combination
               of human and machine innovation and selection. It also combines
               the requirements of multimodal representational learning with
               various aspects of contextual plasticity to prepare Va.Si.Li-Lab
               as a system that can be used for experimental research. The chapter
               is conceptual in nature, designing a system of requirements using
               the example of Va.Si.Li-Lab to outline an experimental environment
               in which the study of Critical Online Reasoning (COR) as a group
               process becomes possible. Although the chapter illustrates some
               of these requirements with realistic data from the field of simulation-based
               learning, the focus is still conceptual rather than experimental,
               hypothesis-driven. That is, the chapter is concerned with the
               design of a technology for future research into COR processes.},

  abstract  = {Multimodal communication research focuses on how different means
               of signalling coordinate to communicate effectively. This line
               of research is traditionally influenced by fields such as cognitive
               and neuroscience, human-computer interaction, and linguistics.
               With new technologies becoming available in fields such as natural
               language processing and computer vision, the field can increasingly
               avail itself of new ways of analyzing and understanding multimodal
               communication. As a result, there is a general hope that multimodal
               research may be at the ``precipice of greatness'' due to technological
               advances in computer science and resulting extended empirical
               coverage. However, for this to come about there must be sufficient
               guidance on key (theoretical) needs of innovation in the field
               of multimodal communication. Absent such guidance, the research
               focus of computer scientists might increasingly diverge from crucial
               issues in multimodal communication. With this paper, we want to
               further promote interaction between these fields, which may enormously
               benefit both communities. The multimodal research community (represented
               here by a consortium of researchers from the Visual Communication
               [ViCom] Priority Programme) can engage in the innovation by clearly
               stating which technological tools are needed to make progress
               in the field of multimodal communication. In this article, we
               try to facilitate the establishment of a much needed common ground
               on feasible expectations (e.g., in terms of terminology and measures
               to be able to train machine learning algorithms) and to critically
               reflect possibly idle hopes for technical advances, informed by
               recent successes and challenges in computer science, social signal
               processing, and related domains.},

  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

               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

  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
               to motivate the broad applicability of Va.Si.Li-Lab and its data

  abstract  = {Transformer-based models are now predominant in NLP.They outperform
               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
               {--} in some cases even better.}

               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.}

               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).},

               a lexical resource for Medieval Latin that is used both for the
               lemmatization of Latin texts and for the post-editing of lemmatizations.
               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
               post-correction of lemmatizations using a limited crowdsourcing
               process aimed at continuous review and updating of the FLL. Starting
               from the texts resulting from this lemmatization process, we describe
               the extension of the FLL by means of word embeddings, whose interactive
               traversing by means of SemioGraphs completes the digital enhanced
               hermeneutic circle. In this way, the article argues for a more
               comprehensive understanding of lemmatization, encompassing classical
               machine learning as well as intellectual post-corrections and,
               in particular, human computation in the form of interpretation

  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.},

               refer to the same entity. The F1-Scores on these task have been
               greatly improved by new developed End2End-approaches and transformer
               networks. The inclusion of CR as a pre-processing step is expected
               to lead to improvements in downstream tasks. The paper examines
               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.},
