Abstract
spicos II enables an on-going dialogue to take place with an office data-bank. This represents a further development of spicos I that, linguistically, was confined to a simple question-answer scheme. spicos II is speaker-adaptable and incorporates a vocabulary of some 1,200 words. The present article gives an overview of the elements connected with linguistic analysis. These elements are governed by a dialogue module that controls the dialogue and, by means of appropriate follow-up questions, avoids possible communications difficulties. The syntactic analysis is based on an augmented phrase-structure grammar. At the same time, semantic constraints are checked by means of a semantic network. Syntactic structure, together with semantic features and the results of the resolution of anaphoric bindings and a separate formal representation of discourse referents, is used to build formal-logic semantic representations of utterances. User presuppositions are also represented. From these formal representations date-bank queries are generated.
