Abstract

WISBER is a natural language consultation system which covers the whole spectrum of natural language processing including analysis, response determination, and generation. In this paper we will describe the components of the semantic-pragmatic level which start with an initial semantic representation of the user’s input and produce a semantic representation of the system’s response. On the analysis side handling of quantifier scope and distributivity, modal verbs, and different sentence types is featured. Then the dialog control component, which decides how to continue the dialog is described. It works with time dependent propositional attitudes, which is an essentially new approach. On the generation side, we examine the methods for paraphrasing and constructing noun phrases. Finally we present some of our experience in designing and implementing the system.
