Abstract
The following paper describes FSS-WASTL, a system for the acquisition of semantic knowledge within XTRA — a natural language access system to expert systems. Starting from user-supplied example utterances, hypotheses for lexical entries are induced, which then are refined top down through interactive classification. The refinement process of FSS-WASTL is a variant of the well-known KLONE classification procedure and is an extension of T. Finin's interactive classifier. The integration of XTRA's natural language generator, which is a highlight of FSS-WASTL, allows for the paraphrasing of the user's input for clarification purposes. FSS-WASTL is compared with other research systems. It is argued that this approach can be transfered to applications beyond the natural language domain.
This research has been supported by the German Science Foundation in its Special Collaborative Research Programme on Artificial Intelligence and Knowledge Based Systems (SFB 314).
