Abstract
The use of expert systems within information retrieval systems (IRS) seems to be an interesting way, particularly for the query process. Nevertheless we must examine what knowledge we need. We think that the thesaurus may be the kernel of which knowledge: for this, we must define it larger than in classical IRS. After some recalls about what may be the principal features of a query expert system, we discuss about the relationship between thesaurus and a query expert system. The problem is to determine if the thesaurus must be integrated within the knowledge base. In fact this choice is an architecture problem of the expert system. We analyze, in parallel, the effects of this choice about thesaurus representation, expert system functionalities, expert system architecture
