Linking linguistic and non-linguistic information

摘要

Natural language semantics in systems for text understanding depends on linguistic surface structure and on knowledge about the domain of application. Whereas linguistic theory tends to prefer the former aspect, developments in artificial intelligence seem to favor the latter. Work in the knowledge engineering group of the LILOG project on a text understanding system, which integrates both aspects, gave rise to the following considerations. The main goal of this article is to point at some difficulties in linking domain knowledge to knowledge about language suggesting some directions one may take to overcome these problems.
