Discourse analysis for a Legal Expert System

  • Hubert Lehmann
  • Franz Guenthner


This paper deals with discourse analysis, with specific reference to the Linguistic and Logic Based Legal Expert System, LEX. In the LEX project we concentrated on a few arbitrarily selected court decisions, extracted the case descriptions, and then added the necessary background knowledge to our prototype expert system to analyze the case descriptions and to deduce the answers to some juridical questions. In this paper we present and comment on a typical discourse representation structure for an accident description in the corpus we studied.
