    [Abstract] [BibTeX]

    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.

    [Abstract] [BibTeX]

    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 model.

    Despite the great importance of the Latin language in the past, there are relatively few resources available today to develop 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).

    In this article we present the Frankfurt Latin Lexicon (FLL), 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 processes based on graph representations of the underlying lexical resources.

    [Abstract] [BibTeX]

    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.

    [Abstract] [BibTeX]

    Coreference resolution (CR) aims to find all spans of a text that 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.

      abstract  = {Coreference resolution (CR) aims to find all spans of a text that 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.},
