Query Rewriting, Context, Rules
When users access applications, they aim to obtain useful information. Sometimes, however, the user needs to reformulate submitted queries several times and go through many answers until a satisfactory set of answers is achieved. In this scenario, the user may be in different contexts, and these contexts may change frequently. A context surrounding his tasks (e.g., queries), for instance, may be built from his specific interests, location or expertise. In this work, we address the issue of rewriting queries considering the context acquired at query submission time. To this end, we propose a query rewriting approach, which makes use of context-based rules to produce new related expanded or relaxed queries. In this paper, we describe our approach and present some results we have obtained.
