- Abstract
- Das Buch gibt eine umfassende Darstellung einer Methodik zur Interpretation und Bedeutungsrepräsentation natürlichsprachlicher Ausdrücke. Diese Methodik der "Mehrschichtigen Erweiterten Semantischen Netze", das sogenannte MultiNet-Paradigma, ist sowohl für theoretische Untersuchungen als auch für die automatische Verarbeitung natürlicher Sprache auf dem Rechner geeignet. Im ersten Teil des zweiteiligen Buches werden grundlegende Probleme der semantischen Repräsentation von Wissen bzw. der semantischen Interpretation natürlichsprachlicher Phänomene behandelt. Der zweite Teil enthält eine systematische Zusammenstellung des gesamten Repertoires von Darstellungsmitteln, die jeweils nach einem einheitlichen Schema beschrieben werden. Er dient als Kompendium der im Buch verwendeten formalen Beschreibungsmittel von MultiNet. Die vorgestellten Ergebnisse sind eingebettet in ein System von Software-Werkzeugen, die eine praktische Nutzung der MultiNet-Darstellungsmittel als Formalismus zur Bedeutungsrepräsentation im Rahmen der automatischen Sprachverarbeitung sichern. Hierzu gehören: eine Werkbank für den Wissensingenieur, ein Übersetzungssystem zur automatischen Gewinnung von Bedeutungsdarstellungen natürlichsprachlicher Sätze und eine Werkbank für den Computerlexikographen. Der Inhalt des Buches beruht auf jahrzehntelanger Forschung auf dem Gebiet der automatischen Sprachverarbeitung und wurde mit Vorlesungen zur Künstlichen Intelligenz und Wissensverarbeitung an der TU Dresden und der FernUniversität Hagen wiederholt in der Hochschullehre eingesetzt. Als Vorkenntnisse werden beim Leser lediglich Grundlagen der traditionellen Grammatik und elementare Kenntnisse der Prädikatenlogik vorausgesetzt.

- Abstract
- Dieser Beitrag beschreibt die Strukturierungsprinzipien und Anwendungskontexte lexikalisch-semantischer Wortnetze, insbesondere des deutschen Wortnetzes GermaNet. Wortnetze sind zurzeit besonders populäre elektronische Lexikonressourcen, die große Abdeckungen semantisch strukturierter Datenfür verschiedene Sprachen und Sprachverbünde enthalten. In Wortnetzen sind die häufigsten und wichtigsten Konzepte einer Sprache mit ihren elementaren Bedeutungsrelationen repräsentiert. Zentrale Anwendungen für Wortnetze sind u.a. die Lesartendisambiguierung und die Informationserschließung. Der Artikel skizziert die neusten Szenarien, in denen GermaNet eingesetzt wird: die Semantische Informationserschließung und die Integration allgemeinsprachlicher Wortnetze mit terminologischen Ressourcen vordem Hintergrund der Datenkonvertierung in OWL.

- Abstract
- There have been many attempts at classifying the semantic modification relations (R) of N + N compounds but this work has not led to the acceptance of a definitive scheme, so that devising a reusable classification is a worthwhile aim. The scope of this undertaking is extended to other binominal lexemes, i.e. units that contain two thing-morphemes without explicitly stating R, like prepositional units, N + relational adjective units, etc. The 25-relation taxonomy of Bourque (2014) was tested against over 15,000 binominal lexemes from 106 languages and extended to a 29-relation scheme ("Bourque2") through the introduction of two new reversible relations. Bourque2 is then mapped onto Hatcher's (1960) four-relation scheme (extended by the addition of a fifth relation, similarity , as "Hatcher2"). This results in a two-tier system usable at different degrees of granularities. On account of its semantic proximity to compounding, metonymy is then taken into account, following Janda's (2011) suggestion that it plays a role in word formation; Peirsman and Geeraerts' (2006) inventory of 23 metonymic patterns is mapped onto Bourque2, confirming the identity of metonymic and binominal modification relations. Finally, Blank's (2003) and Koch's (2001) work on lexical semantics justifies the addition to the scheme of a third, superordinate level which comprises the three Aristotelean principles of similarity, contiguity and contrast.

- Abstract
- Natural Language is not only the most important means of communication between human beings, it is also used over historical periods for the preservation of cultural achievements and their transmission from one generation to the other. During the last few decades, the flod of digitalized information has been growing tremendously. This tendency will continue with the globalisation of information societies and with the growing importance of national and international computer networks. This is one reason why the theoretical understanding and the automated treatment of communication processes based on natural language have such a decisive social and economic impact. In this context, the semantic representation of knowledge originally formulated in natural language plays a central part, because it connects all components of natural language processing systems, be they the automatic understanding of natural language (analysis), the rational reasoning over knowledge bases, or the generation of natural language expressions from formal representations. This book presents a method for the semantic representation of natural language expressions (texts, sentences, phrases, etc.) which can be used as a universal knowledge representation paradigm in the human sciences, like linguistics, cognitive psychology, or philosophy of language, as well as in computational linguistics and in artificial intelligence. It is also an attempt to close the gap between these disciplines, which to a large extent are still working separately.

- Abstract
- Full-text documents are a vital and rapidly growing part of online biomedical information. A single large document can contain as much information as a small database, but normally lacks the tight structure and consistent indexing of a database. Retrieval systems will often miss highly relevant parts of a document if the document as a whole appears irrelevant. Access to full-text information is further complicated by the need to search separately many disparate information resources. This research explores how these problems can be addressed by the combined use of 2 techniques: 1) natural language processing for automatic concept-based indexing of full text, and 2) methods for exploiting the structure and hierarchy of full-text documents. We describe methods for applying these techniques to a large collection of full-text documents drawn from the Health Services / Technology Assessment Text (HSTAT) database at the NLM and examine how this hierarchical concept indexing can assist both document- and source-level retrieval in the context of NLM's Information Source Map project
