Abstract

Knowledge integration is a very important and useful technique to combine information from different sources and different formats. In the Information Retrieval field, integration of knowledge can be understood in many ways. In this paper a method of user personalization in information retrieval using integration technique is presented. As user delivers new knowledge about himself, this knowledge should be integrated with previous knowledge contained in the user profile. Our proposed method is analyzed in terms of integration postulates. A list of desirable properties of this method and its proofs are presented. Simulated experimental evaluation has shown that proposed method is effective and the updated profile is proper since it is closer and closer to the user preferences.
