Abstract: "In proposing a searching strategy in a hypertext environment, we have considered three criteria; (1) the user's information need must be very easily expressed; (2) the retrieval process should use multiple sources of evidence, including multiple indexing schemes and multiple search mechanisms; and (3) the hypertext links should be exploited in order to find more relevant material and 'good' starting points for browsing. To satisfy these three criteria, we have implemented a hypertext system where the user, instead of writing a formal query, just selects relevant terms and/or documents. Based on multiple indexing schemes, Bayesian networks are used to manage the indexing spaces and to store the user's information need.
