PERCIRS: a System to Combine Personalized and Collaborative Information Retrieval
Résumé
A new personalized CIR system, called PERCIRS, is presented based on the User Profile Similarity Calculation (UPSC) formulas. To this aim, we propose several UPSC formulas as well as two techniques to evaluate them. As our proposed CIR system is personalized, so it cannot be evaluated by Cranfield like evaluation techniques (e.g. TREC). Hence in this paper we propose a new user-centric mechanism which enables us to evaluate PERCIRS. This mechanism is generic and can be used to evaluate any other personalized IR system.
