Graph-Based Profile Similarity Calculation Method and Evaluation

摘要

Collaborative Information Retrieval (CIR) is a new technique for resolving the current problem of information retrieval systems. A CIR system registers the previous user interactions to response to the subsequent user queries more efficiently. But, the goals and the characteristics of two users may be different; so when they send the same query to a CIR system, they may be interested in two different lists of documents. To resolve this problem, we have developed a personalized CIR system, called PERCIRS, which is based on the similarity between two user profiles. In this paper, we propose a new method for User Profile Similarity Calculation UPSC. Finally, we introduce a mechanism for evaluating UPSC methods.
