This paper describes the SDC PUNDIT, (Prolog UNDerstands Integrated Text), system for processing natural language messages. 1 PUNDIT, written in Prolog, is a highly modular system consisting of dis- tinct syntactic, semantic and pragmatics com- ponents. Each component draws on one or more sets of data, including a lexicon, a broad-coverage gram- mar of EngLish, semantic verb decompositions, rules mapping between syntactic and semantic consti- tuents, and a domain model. This paper discusses the communication between the syntactic, semantic and pragmatic modules that is necessary for making implicit linguistic information explicit. The key is letting syntax and semantics recognize missing linguistic entities as implicit enti- ties, so that they can be labelled as such, and refer- enee resol...
