Abstract

In this paper the model of interests and preferences of information retrieval system users is presented. The paper starts with a short overview on areas of user profiles applications. Subsequently, a method to represent user profiles in the field of Web document retrieval by using query terms and weighted terms of retrieved documents is presented. The method is based on evaluating the relevance of retrieved documents by the user. The relevant documents are the basis to construct so called subprofiles. The created subprofiles represent user interests and preferences, and are used for the user query modification.
