INFORMATION RETRIEVAL WITH MULTIPLE QUERIES
Yunjie Calvin Xu · Journal of the Association for Information Systems · 2001
Information overload becomes an immediate issue as the Internet prospers.To improve information retrieval effectiveness, we propose a sum-cosine procedure which is a meta-search procedure that integrates retrieval results from multiple queries.Based on this procedure, we also give its theoretical justification.We show that it improves performance through better estimation of user's information need and a solid integration method.We also show that meta-search with multiple queries is essentially a special form of relevance feedback.Our empirical evidence is fully consistent with theoretical analysis.
