Abstract

Modeling users' information interests and needs is one of the most important tasks in the area of personalization in information retrieval domain. In this paper the statistical model of information retrieval system is considered. A method for tuning the user profile based on analysis of user preferences dynamics is experimentally evaluated to check whether with growing history of user activity the created user profile can come closer to his preferences. As statistical analysis of series of simulations have shown, proposed method of user profile actualization is effective in the sense of distance between user preferences and his profile.
