Query enhancement by user profiles

Abstract. We describe a theoretical model and an on-going series of experiments aimed at a priori query enhancement. The model presents a synthesis of concepts from retrospective and current awareness retrieval systems, employing the user profile as a factor in interpreting a query. It is expected that this will provide a more personalized response to queries. i BACKGROUND It may be said that the basic goal of research on information storage and retrieval is to develop better ways of identifying the match between a query and documents that reside within an information system. While this research has many facets, the work described in this paper focuses on one of them-- the a priori enhancement of a query. Earlier work on this facet has generally been focused on improved syntactic and semantic analysis of the query, the use of thesauri and stemming algo-
