Abstract

Demonstrates how a natural language understanding (NLU) system can be developed to utilize low level pragmatic information, primarily the linguistic context, to deal effectively with the linguistic devices of anaphors and ellipsis and allow users to query databases for reference information without the need for menus or fixed phrases and query structures. Describes the components which comprise a NLU system to deal with continuous dialogue. Given that the syntactic and semantic information can produce a suitable information of each utterance, pragmatic information may be used to determine how this contectual information determines the interpretation of subsequent utterances. Suggests that the approach taken allows the system to provide a cooperative response to assist the user in attaining the information seeking goal
