Ein Konzept Zur Komposition der Semantik Aus Bedeutungstragenden Teilen Einer ÅUsserung und Zur Behandlung Alternativer Interpretationen

Abstract

In this paper some special aspects are described that were taken as a basis for the construction of a parser which maps utterances of German language to internal representation structures. The underlying formal framework is the Lexical-Functional Theory. The corresponding formalism is used to process the syntactical and semantical informations simultaneously and in a unique way. Some examples will illustrate the mechanisms which allow to construct the semantical representation of a sentence merely out of its meaningfull parts; this is done by exploiting a special class of functional equations within the LF-Formalism.

An expansion of the formalism enables us to combine alternative syntactical or semantical informations and reduce the arising sets of disjuncts during the proceeding parsing process. This leads to a tool which is able to recognize the ambiguities of an utterance. The difficulties connected with such a reduction algorithm and the implemented solutions are explained.
