Beyond that, he is member of the executive committee of the LOEWE Priority Program Digital Humanities at the Goethe University.

Alexander Mehler studied Information Science and Slavic Studies at the University of Regensburg as well as Computational Linguistics and Economics / Information Systems at Trier University where he graduated in computational linguistics in 1995. From 1994 to 1998 he was project leader and head of the research and development department of the Gesellschaft für Wirtschaftsberatung und Informatik (GWI).

In November 2000 he got his PhD in computational linguistics. His thesis Text Meaning – procedural analysis and representation of structural similarities of texts was awarded a prize by the Circle of Friends of Trier University (incorporated society) in 2001. From 1998 to 2001 he worked as a scientific assistant (AT) and from 2001 to 2004 as a scientific assistant (C1) in the Department of Computational Linguistics at Trier University. In winter term 2003/2004 and 2004/2005 he was visiting professor at Karl-Franzens-University Graz, Austria. From April 2004 to August 2008 he was assistant professor (Juniorprofessor) for Text Technology at Bielefeld University. Since September 2008, Alexander Mehler has been the head of the competence center Computing in the Humanities at Goethe University. In 2009, Alexander Mehler got a call by the Faculty of Technology of the University of Bielefeld to a professorship (W2) in Text Technology/Applied Computational Linguistic, which he accepted in July 2009. In March 2010, he got a call by the Goethe-University Frankfurt am Main to a professorship (W2) in Text Technology/Applied Computational Linguistic, Institute for Informatics, which he accepted in Mai 2010. In 2009, Alexander Mehler got a call by the TU Chemnitz to a professorship (W3) in Technical Communication, and in 2013, a call by the University of Leipzig to a professorship (W3) in Computational Humanities, Institute for Informatics. Alexander Mehler is member of several scientific associations. He belongs to the executive committee of the German Society for Computational Linguistics & Language Technology where he currently heads the research group Quantitative Corpus Linguistics and is a member of the consulting board. Alexander Mehler was head of the research group Computational Semiotics of the Deutsche Gesellschaft für Semiotik. Further, he is a member of the Gesellschaft für Kognitionswissenschaft, of the Association for Computational Linguistics and of the Gesellschaft für Informatik. Since 2004, Alexander Mehler has been editor of the Journal for Language Technology and Computational Linguistics and reviewer of many scientific journals and book series in the field of computational linguistics.

Since 2005, Alexander Mehler has been project leader of the DFG-funded research project Induction of Document Grammars for the Representation of Logical Hypertext Document Structures as part of the Research Group Text Technological Information Modeling (speaker: Prof. Dr. Dieter Metzing, Bielefeld University). Together with Prof. Dr. Gerhard Heyer (Leipzig University), Alexander Mehler acquired the DFG (Deutsche ForschungsgemeinschaftGerman Research Foundation) funded research project Topic-Oriented Peer-to-Peer Agents in Digital Libraries. Further, since 2006 he has been project leader of the DFG-funded research project Multimodal Alignment Corpora: Statistical Modeling and Information Management as well as of the DFG-project Dialogue Games and Group Dynamics (together with Prof. Dr. Gerhard Jäger, Bielefeld University) as part of the Collaborative Research Center (CRC) 673 Alignment in Communication (speaker: Prof. Dr. Gert Rickheit, Bielefeld University). Since 2006, Alexander Mehler has been member of the executive committee of the CRC 673. Further, he organized and presented the linguistics part of the Excellence Cluster (EC) 277 Cognitive Interaction Technology (speaker: Prof. Dr. Helge Ritter, Bielefeld University) to the reviewers of the DFG. In the framework of this cluster of excellence, Alexander Mehler acquired the research project Knowledge Enhanced Embodied Cognitive Interaction Technologies (KnowCITs) together with Prof. Dr. Ipke Wachsmuth (Bielefeld University) in 2008. Beyond that, Alexander Mehler acquired (as the coordinator and principal investigator) the BMBF (Bundesministerium für Bildung und Forschung (BMBF) – Federal Ministry of Education and Research) joint research project Linguistic Networks – Text Technological Representation, Computational Linguistic Synthesis and Physical Modeling in the framework of the BMBF-Priority Research Program New Natural Scientific Methods and Technologies in the Humanities. Alexander Mehler acquired the DFG-research project Automatic Enrichment of OAI Metadata by Computational Linguistic Methods and Development of Services for the Topic-Related Networking of Repositories in the framework of the DFG-priority program Electronic Publications – Buildup and Networking of Repositories (in collaboration with Dr. Michael Höppner, University Library Bielefeld, and Prof. Dr. Gerhard Heyer, Leipzig University). Further, Alexander Mehler contributed as a principal investigator to the acquisition of the LOEWE-center Digital Humanities (Speaker: Prof. Dr. Jost Gippert) where he belongs to the executive committee and represents the area of computational humanities. In this multidisciplinary research project, Alexander Mehler investigates and develops algorithms for the automatic analysis of historical documents. Recently, he acquired the BMBF-research project Historical Semantic Spaces as part of the BMBF-Priority Research Program Digital Humanities, in which he cooperates with historians (Prof. Dr. Bernhard Jussen) and philologists (Prof. Dr. Barbara Job, Bielefeld university; Prof. Dr. Peter Koch, Eberhard-Karls-Universität Tübingen; Prof. Dr. Maria Selig, Universität Regensburg) to explore the laws of social-semantic change.

These research projects document the theoretical and practical research activities of Alexander Mehler. They range from text and web mining to alignment in communication, social ontologies and their utilization by means of cognitive interaction technologies. The common ground of this research is the computational integration of content and structure modeling of semiotic aggregates and their networking in terms of complex networks.

Alexander Mehler’s research interests focus on the empirical analysis and simulative synthesis of discourse units in spoken and written communication. He aims at a quantitative theory of networking in linguistic systems to enable multi-agent simulations of their life cycle. Alexander Mehler integrates models of semantic spaces with simulation models of language evolution and topological models of network theory to capture the complexity of linguistic information systems. Currently, he is heading several research projects on the analysis of linguistic networks in historical semantics. Most recently he started a research project on kinetic text-technologies that integrates the paradigm of games with a purpose with the wiki way of collaborative writing and kinetic HCI. His research interests include but are not limited to the following topics:

• computational humanities
• complex linguistic networks
• quantitative semantics
• alignment in communication
• kinetic text-technologies
• text & web mining

[Abstract] [BibTeX]

We present the Stolperwege app, a web-based framework for ubiquitous modeling of historical processes. Starting from the art project \textitStolpersteine of Gunter Demnig, it allows for virtually connecting these stumbling blocks with information about the biographies of victims of Nazism. According to the practice of \textitpublic history, the aim of Stolperwege is to deepen public knowledge of the Holocaust in the context of our everyday environment. Stolperwege uses an information model that allows for modeling social networks of agents starting from information about portions of their life. The paper exemplifies how Stolperwege is informationally enriched by means of historical maps and 3D animations of (historical) buildings.

[Abstract] [BibTeX]

The paper presents Wikidition, a novel text mining tool for generating online editions of text corpora. It explores lexical, sentential and textual relations to span multi-layer networks (linkification) 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.

[Abstract] [BibTeX]

We introduce a new text technology, called Wikidition, which automatically generates large scale editions of corpora of natural language texts. Wikidition combines a wide range of text mining tools for automatically linking lexical, sentential and textual units. This includes the extraction of corpus-specific lexica down to the level of syntactic words and their grammatical categories. To this end, we introduce a novel measure of text reuse and exemplify Wikidition by means of the capitularies, that is, a corpus of Medieval Latin texts.

[Abstract] [BibTeX]

The analysis of longitudinal corpora of historical texts requires the integrated development of tools for automatically preprocessing these texts and for building representation models of their genre- 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.

title={Towards a Network Model of the Coreness of Texts: An Experiment in Classifying Latin Texts using the TTLab Latin Tagger},
abstract={The analysis of longitudinal corpora of historical texts requires the integrated development of tools for automatically preprocessing these texts and for building representation models of their genre- 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] [BibTeX]

This paper provides a theoretical assessment of gestures in the 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.

[Abstract] [BibTeX]

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.

[Abstract] [BibTeX]

We provide a new, theoretically motivated evaluation grid for assessing the conversational achievements of Artificial Dialog Companions (ADCs). The grid is spanned along three grounding problems. 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.

This paper presents a classifier of text readability based on information-theoretic features. The classifier was developed based on a linguistic approach to readability that explores lexical, syntactic and semantic features. For this evaluation we extracted a corpus of 645 articles from Wikipedia together with their quality judgments. We show that information-theoretic features perform as well as their linguistic counterparts even if we explore several linguistic levels at once.

There are many languages considered to be low-density languages, either because the population speaking the language is not very large, or because insufficient digitized text material is available in the language even though millions of people speak the language. Bangla is one of the latter ones. Readability classification is an important Natural Language Processing (NLP) application that can be used to judge the quality of documents and assist writers to locate possible problems. This paper presents a readability classifier of Bangla textbook documents based on information-theoretic and lexical features. The features proposed in this paper result in an F-score that is 50% higher than that for traditional readability formulas.

[Abstract] [BibTeX]

We present an empirical account of multimodal ensembles based on Hjelmslev’s notion of selection. This is done to get measurable evidence for the existence of speech-and-gesture ensembles. Utilizing information theory, we show that there is an information transmission that makes a gestures’ representation technique predictable when merely knowing its lexical affiliate – in line with the notion of the primacy of language. Thus, there is evidence for a one-way coupling – going from words to gestures – that leads to speech-and-gesture alignment and underlies the constitution of multimodal ensembles.

[Abstract] [BibTeX]

We introduce WikiNect as a kinetic museum information system that 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.

[Abstract] [BibTeX]

We present a network model of dialog lexica, called TiTAN (Two-layer 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.

Currently, the area of translation studies lacks corpora by which translation scholars can validate their theoretical claims, for example, regarding the scope of the characteristics of the translation relation. In this paper, we describe a customized resource in the area of translation studies that mainly addresses research on the properties of the translation relation. Our experimental results show that the Type-Token-Ratio (TTR) is not a universally valid indicator of the simplification of translation.

[Abstract] [BibTeX]

The Naming Game (NG) has become a vivid research paradigm for simulation studies on language evolution and the establishment of naming conventions. Recently, NGs were used for reconstructing 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.

[Abstract] [BibTeX]

Ancient corpora contain various multilingual patterns. This imposes numerous problems on their manual annotation and automatic processing. We introduce a lexicon building system, called Lexicon Expander, that has an integrated language detection module, Language Detection (LD) Toolkit. The Lexicon Expander post-processes the output of the LD Toolkit which leads to the improvement of f-score and accuracy values. Furthermore, the functionality of the Lexicon Expander also includes manual editing of lexical entries and automatic morphological expansion by means of a morphological grammar.

[Abstract] [BibTeX]

In the area of digital library services, the access to subject-specific 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.

[Abstract] [BibTeX]

Checking for readability or simplicity of texts is important for 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.

[Abstract] [BibTeX]

This article presents an approach to automatic language classification by means of linguistic networks. Networks of 11 languages were constructed from dependency treebanks, and the topology of these networks serves as input to the classification algorithm. The results match the genealogical similarities of these languages. In addition, we test two alternative approaches to automatic language classification – one based on n-grams and the other on quantitative typological indices. All three methods show good results in identifying genealogical groups. Beyond genetic similarities, network features (and feature combinations) offer a new source of typological information about languages. This information can contribute to a better understanding of the interplay of single linguistic phenomena observed in language.

[Abstract] [BibTeX]

Currently, some simulative accounts exist within dynamic or evolutionary 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.

[Abstract] [BibTeX]

In this article, we test a variant of the Sapir-Whorf Hypothesis 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.

[Abstract] [BibTeX]

This chapter introduces a novel class of graphs: Minimum Spanning 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.

Delivering linguistic resources and easy-to-use methods to a broad public in the humanities is a challenging task. On the one hand users rightly demand easy to use interfaces but on the other hand want to have access to the full flexibility and power of the functions being offered. Even though a growing number of excellent systems exist which offer convenient means to use linguistic resources and methods, they usually focus on a specific domain, as for example corpus exploration or text categorization. Architectures which address a broad scope of applications are still rare. This article introduces the eHumanities Desktop, an online system for corpus management, processing and analysis which aims at bridging the gap between powerful command line tools and intuitive user interfaces.

[Abstract] [BibTeX]

In dyadic communication, both interlocutors adapt to each other 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.

[Abstract] [BibTeX]

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.

website={http://biecoll.ub.uni-bielefeld.de/frontdoor.php?source_opus=5001&la=de},
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.}}

[Abstract] [BibTeX]

This paper presents an approach using social semantics for the task of topic labelling by means of Open Topic Models. Our approach 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] [BibTeX]

In addition to the well-known linguistic alignment processes in dyadic communication – e.g., phonetic, syntactic, semantic alignment – we provide evidence for a genuine multimodal alignment process, namely semiotic alignment. Communicative elements from different modalities 'routinize into' cross-modal 'super-signs', which we call multimodal ensembles. Computational models of human communication are in need of expressive models of multimodal ensembles. In this paper, we exemplify semiotic alignment by means of empirical examples of the building of multimodal ensembles. We then propose a graph model of multimodal dialogue that is expressive enough to capture multimodal ensembles. In line with this model, we define a novel task in machine learning with the aim of training classifiers that can detect semiotic alignment in dialogue. This model is in support of approaches which need to gain insights into realistic human-machine communication.

[Abstract] [BibTeX]

This paper presents a simulation model of self-organizing lexical networks. Its starting point is the notion of an association game in which the impact of varying community models is studied on the emergence of lexical networks. The paper reports on experiments whose results are in accordance with findings in the framework of the naming game. This is done by means of a multilevel network model in which the correlation of social and of linguistic networks is studied

[Abstract] [BibTeX]

In this paper we present a corpus representation format which unifies the representation of a wide range of dependency treebanks within a single model. This approach provides interoperability and reusability of annotated syntactic data which in turn extends its applicability within various research contexts. We demonstrate our approach by means of dependency treebanks of 11 languages. Further, we perform a comparative quantitative analysis of these treebanks in order to demonstrate the interoperability of our approach.

[Abstract] [BibTeX]

We present initial results from an international and multi-disciplinary research collaboration that aims at the construction of a reference corpus of web genres. The primary application scenario for which we plan to build this resource is the automatic identification of web genres. Web genres are rather difficult to capture and 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 reference corpus of web genres.

[Abstract] [BibTeX]

This article elaborates a framework for representing and classifying 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.

[Abstract] [BibTeX]

Texts can be distinguished in terms of their content, function, 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.

This chapter introduces a variant of the principle of compositionality 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.

H.: MusicBLASTgapped sequence alignment for MIR, in: Proceedings of the 5th International Conference on Music Information Retrieval (ISMIR), (2004)], to measure the structural similarity of unlabeled, hierarchical, and directed graphs. More precisely, i f h denotes the maximal length of a path from the root to a leaf of a given hierarchical and directed graph ^ H, w e align out-degree and in-degree sequences induced by the vertex sequences on a level i , 0 6 i 6 h . On the basis of the level alignments, we construct measured values and prove that they are similarity measures. In our algorithm, which uses the well-known technique of dynamic programming, the alignments of out-degree and in-degree sequences are decoupled. Therefore, we obtain a family (d i (^ H 1 ^ H 2)) 16i63 of graph similarity measures. As an applica-tion, we examine the measures on a graph corpus of 464 graphs, where the graphs represent web-based hypertext structures (websites). 2000 Mathematics Subject Classification: Primary 05C75, 05C20, 68R155 Secondary 90C39, 68R10, 91B82.

More precisely, i f h denotes the maximal length of a path from the root to a leaf of a given hierarchical and directed graph ^ H, w e align out-degree and in-degree sequences induced by the vertex sequences on a level i , 0 6 i 6 h . On the basis of the level alignments, we construct measured values and prove that they are similarity measures. In our algorithm, which uses the well-known technique of dynamic programming, the alignments of out-degree and in-degree sequences are decoupled. Therefore, we obtain a family (d i (^ H 1 ^ H 2)) 16i63 of graph similarity measures. As an applica-tion, we examine the measures on a graph corpus of 464 graphs, where the graphs represent web-based hypertext structures (websites). 2000 Mathematics Subject Classification: Primary 05C75, 05C20, 68R155 Secondary 90C39, 68R10, 91B82.

[Abstract] [BibTeX]

In this paper, we discuss the structure based classification of documents based on their logical document structure, i.e., their DOM trees. We describe a method using predefined structural features and also four tree kernels suitable for such structures. We evaluate the methods experimentally on a corpus containing the DOM trees of newspaper articles, and on the well-known SUSANNE corpus. We will demonstrate that, for the two corpora, many text types can be learned based on structural features only.

[Abstract] [BibTeX]

The Word Wide Web is a continuous challenge to machine learning. 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.

[Abstract] [BibTeX]

In this paper we describe a simulation model of terminological alignment in a multiagent community. It is based on the notion of an association game which is used instead of the classical notion of a naming game (Steels, 1996). The simulation model integrates a small world-like agent community which restricts agent communication. We hypothesize that this restriction is decisive when it comes to simulate terminological alignment based on lexical priming. The paper presents preliminary experimental results in support of this hypothesis.

[Abstract] [BibTeX]

In this paper, we deal with classifying texts into classes which 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.

[Abstract] [BibTeX]

In this paper, we discuss kernels that can be applied for the classification of XML documents based on their DOM trees. DOM 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.

[Abstract] [BibTeX]

Gegenstand des folgenden Aufsatzes ist der konnotative Aspekt der Bedeutungen von Texten. Den Ausgangspunkt der Überlegungen zur Konnotation des Textes bildet die Auffassung, wonach Wort- und Textbedeutungskonstitution Ergebnis eines zirkulären Prozesses sind, der für die Emergenz einer Hierarchie ineinander geschachtelter Spracheinheiten verantwortlich zeichnet. Der Prozeß 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 Kompositionalitätsprinzips, derzufolge die Bedeutungen sprachlicher Einheiten als fixierte, kontextfreie Größen vorauszusetzen sind, behandelt der vorliegende Ansatz bereits die lexikalische Bedeutung als Größe, die in Abhängigkeit 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' Repräsentationen zerlegbar. Die hierarchische Organisation von Texten erweist sich insofern als komplex, als ihre Bedeutungen aus einem zirkulären Prozeß resultieren, der bestätigend und/oder verändernd auf die Bedeutungen der Textkonstituenten einwirkt. Diese Zirkularität bedingt, daß 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 Verwendungsregularitäten von Wörtern auf der Basis eines zweistufigen Verfahrens analysiert, welches die syntagmatischen und paradigmatischen Regularitäten des Wortgebrauches berücksichtigt. Die Rolle der Satzebene innerhalb des Prozesses der konnotativen Textbedeutungskonstitution wird angedeutet. Abschließend erfolgt eine Exemplifizierung des Algorithmus anhand der automatischen Analyse eines Textcorpus.

[Abstract] [BibTeX]

Facing the retrieval problem according to the overwhelming set 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.

title={Towards Logical Hypertext Structure - A Graph-Theoretic Perspective},
abstract={Facing the retrieval problem according to the overwhelming set 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.}}

[Abstract] [BibTeX]

Hypertext categorization is the task of automatically assigning 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) in the area of web mining.

[Abstract] [BibTeX]

Most known methods for measuring the structural similarity of 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.

[Abstract] [BibTeX]

Die automatische Konversion von Texten in Hypertexte ist mit der Erwartung verbunden, computerbasierte Rezeptionshilfen zu gewinnen. Dies betrifft insbesondere die Bewältigung der ungeheuren Menge an Fachliteratur im Rahmen der Wissenschaftskommunikation. Von einem thematisch relevanten Text zu einem thematisch verwandten Text per Hyperlink direkt gelangen zu können, stellt einen Anspruch dar, dessen Erfüllung mittels digitaler Bibliotheken näher gerückt zu sein scheint. Doch wie lassen sich die Kriterien, nach denen Texte automatisch verlinkt werden, genauer begründen? Dieser Beitrag geht dieser Frage aus der Sicht textlinguistischer Modellbildungen nach. Er zeigt, dass parallel zur Entwicklung der Textlinguistik, wenn auch mit einer gewissen Verzögerung, Konversionsansätze entwickelt wurden, die sich jeweils an einer bestimmten Stufe des Textbegriffs orientieren. Der Beitrag weist nicht nur das diesen Ansätzen gemeinsame Fundament in Form der so genannten Explikationshypothese nach, sondern verweist zugleich auf grundlegende Automatisierungsdefizite, die mit ihnen verbunden sind. Mit systemisch-funktionalen Hypertexten wird schließlich ein Ansatz skizziert, der darauf zielt, den Anspruch nach textlinguistischer Fundierung und Automatisierbarkeit zu vereinen.

[Abstract] [BibTeX]

Corpus linguistics and related disciplines which focus on statistical 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.

Beiträge 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 gängigen Verfahren der Informationsaufbereitung und Informationserschließung gegenübergestellt. Es wird bemängelt, dass sich das IR weitgehend darin erschöpft, Teilmengen von Textkollektionen auf Suchanfragen hin aufzufinden und in der Regel bloß listenförmig anzuordnen. Das auf diese Weise dargestellte Spannungsverhältnis von Informationsexplosion und Defiziten bestehender IR-Verfahren bildet den Hintergrund für die Entwicklung von Verfahren zur automatischen Verarbeitung textueller Einheiten, die sich stärker an den Anforderungen von Informationssuchenden orientieren. Anders ausgedrückt: Mit der Einführung der Neuen Medien wächst die Bedeutung digitalisierter Dokumente als Primärmedium 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 Dokumenterschließung 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 Flexibilität 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 lässt bereits die Namensgebung erkennen, dass es sich um Analogiebildungen zu dem (nur unwesentlich älteren) 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, während Hearst (1999a) im Gegensatz hierzu Informationsextraktion und Textkategorisierung explizit aus dem Bereich des explorativen Text Mining ausschließt.

[Abstract] [BibTeX]

Dieser Beitrag behandelt Verfahren zur automatischen Erzeugung 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.

[Abstract] [BibTeX]

Im Zuge der Web-basierten Kommunikation tritt die Frage auf, inwiefern Webpages zum Zwecke ihrer inhaltsorientierten Filterung kategorisiert werden können. Diese Studie untersucht zwei Phänomene, welche die Bedingung der Möglichkeit einer solchen Kategorisierung betreffen (siehe [6]): Mit dem Begriff der funktionalen Aquivalenz beziehen wir uns auf das Phänomen, 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 Phänomen, dass dasselbe Dokument zugleich mehrere Funktions- oder Inhaltskategorien manifestieren kann. Die zentrale Hypothese lautet, dass beide Phänomene 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 die Frage nach der adäquaten Modellierung multimedialer Dokumente.

Der Beitrag beschreibt eine Variante des Kompositionalitätsprinzips der Bedeutung als Grundprinzip für die numerische Analyse unsystematischer Sinnrelationen komplexer Zeichen, das über das Phänomen der perspektivischen Interpretation hinaus gebrauchssemantische Bedeutungsaspekte berücksichtigt. Ziel ist es, ein theoretisches Fundament für korpusanalytische Ansätze in der Semantik, die oftmals die linguistische Interpretierbarkeit ihrer Analyseergebnisse vermissen lassen, zu umreißen. Die Spezifikation des Kompositionalitätsprinzips erfolgt unter Rekurs auf das Modell eines hierarchisch geordneten Constraint-Satisfaction-Prozesses. Hiermit ist das längerfristige Ziel verbunden, das Problem einer defizitären numerischen Textrepräsentation sowie die mangelnde Integration von propositionaler und strukturaler bzw. korpusanalytischer Semantik anzugehen. Die Erörterungen dieses Beitrags sind primär konzeptioneller Natur; sie betreffen die Konzeption einer numerischen Textsemantik zur Vermeidung von Defiziten bestehender Ansätze.

[Abstract] [BibTeX]

In the following, elementary constituents of models in computational semiotics are outlined. This is done by referring to computer simulations as a framework which neither aims to describe artificial sign systems (as done in computer semiotics), nor to realize semiotic functions in “artificial worlds” (as proposed in “artificial semiosis”). Rather, the framework referred to focuses on preconditions of computer-based simulations of semiotic processes. Following this approach, the paper focuses on methodological aspects of computational semiotics.

[Abstract] [BibTeX]

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] [BibTeX]

In the framework of automatic text processing, semantic spaces 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] [BibTeX]

Text representation is a central task for any approach to automatic learning from texts. It requires a format which allows to interrelate texts even if they do not share content words, but deal with similar topics. Furthermore, measuring text similarities raises the question of how to organize the resulting clusters. This paper presents cohesion trees (CT) as a data structure for the perspective, hierarchical organization of text corpora. CTs operate on alternative text representation models taking lexical organization, quantitative text characteristics, and text structure into account. It is shown that CTs realize text linkages which are lexically more homogeneous than those produced by minimal spanning trees.

Semantic spaces are used as a representational format for modeling similarities of signs. As a multidimensional data structure they are bound to the question of how to explore similarity relations of signs mapped onto them. This paper introduces an abstract data structure called dependency scheme as a formal format which encapsulates two types of order relations, whose variable instatiation allows to derive different classes of trees for the hierarchial analysis of text similarity data derived from semantic spaces.

[Abstract] [BibTeX]

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

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}}

[Abstract] [BibTeX]

In diesem Beitrag beschreiben wir den eHumanities Desktop3. Es handelt sich dabei um eine rein webbasierte Umgebung für die texttechnologische Arbeit mit Korpora, welche von der standardisierten Repräsentation textueller Einheiten über deren computerlinguistische Vorverarbeitung bis hin zu Text Mining–Funktionalitäten eine große 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 Händen 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.
