Abstract

To achieve generality, natural language parsers require dictionaries which handle lexical information in a linguistically motivated but computationally viable manner. Various rule formalisms are presented which process orthographic effects, word structure, and lexicai redundancy in a manner which allows the statement of linguistic generalisations with a clear computational interpretation. A compact description of a medium-sized subset of the English lexicon can be stated using these formalisms. The proposed mechanisms have been implemented and tested, but require to be refined further if they are to be regarded as an interesting linguistic theory.
