| Abstract: Nowadays personalization systems becomes more and more famous. Usually, such systems gather information about a user to recommend him better results : web pages, documents, etc. Important aspect of modeling user procedures is to keep the profile up-to-date according to changes of user interests. In this paper a hierarchical model of user profile is considered. Connections between terms in a hierarchy reflects generalization relation. A set of assumption for profile structure is proposed. For such an user profile a method for its adaptation is presented and a quality criterion for this method is proposed. Experimental evaluation has shown that quality criterion is satisfied. |
