Im folgenden Beitrag handelt es sich um die Entwicklung eines semantischen Wörterbuches der deutschen Sprache für maschinelle Sprachverarbeitungssysteme im Rahmen des Projektes "Compreno" bei dem russischen IT-Unternehmen ABBYY. Es wird eine kurze Übersicht über andere elektronische Quellen zur deutschen Sprache gegeben, ferner werden ihre Unterschiede im Vergleich zum Projektwörterbuch analysiert. An einigen Beispielen werden aktuelle Probleme der Computerlexikografie (Bedeutungsunterscheidung, Komposita-Analyse u.a.) und ihre mögliche Lösung in Bezug auf das Projektwörterbuch betrachtet.
This paper provides an overview of current research on a hybrid and robust parsing architecture for the morphological, syntactic and semantic annotation of German text corpora. The novel contribution of this research lies not in the individual parsing modules, each of which relies on state-of-the-art algorithms and techniques. Rather what is new about the present approach is the combination of these modules into a single architecture. This combination provides a means to significantly optimize the performance of each component, resulting in an increased accuracy of annotation.
LTAG semantics for questions
(2004)
This papers presents a compositional semantic analysis of interrogatives clauses in LTAG (Lexicalized Tree Adjoining Grammar) that captures the scopal properties of wh- and nonwh-quantificational elements. It is shown that the present approach derives the correct semantics for examples claimed to be problematic for LTAG semantic approaches based on the derivation tree. The paper further provides an LTAG semantics for embedded interrogatives.
In this paper we propose a compositional semantics for lexicalized tree-adjoining grammar (LTAG). Tree-local multicomponent derivations allow separation of the semantic contribution of a lexical item into one component contributing to the predicate argument structure and a second component contributing to scope semantics. Based on this idea a syntax-semantics interface is presented where the compositional semantics depends only on the derivation structure. It is shown that the derivation structure (and indirectly the locality of derivations) allows an appropriate amount of underspecification. This is illustrated by investigating underspecified representations for quantifier scope ambiguities and related phenomena such as adjunct scope and island constraints.
