Abstract
The paper describes an adaptive information retrieval system that uses heuristic search to sample a document space. IRAS consists of the following parts: (1) the information retrieval a*-algorithm for retrieving relevant documents according to a user's request, and (2) a learning module, based on a knowledge representation system and an approximate probabilistic characterization of relevant documents, to reproduce a user classification of relevant documents and to provide a rule-controlled ranking
