The user interest model is the key technology for us to efficiently obtain personalized high quality resources in huge amounts of data. On the basis of traditional user interest model, combining with the concept of ontology, this paper comes up with a construction method based on ontology semantic tree and space vector method, and its eigenvalue is changing by using forgetting curve. The model describes a theme by using semantic concept tree, and it not only simply to describe the semantic relations between concepts, but also can reflect the user interest drift character. It is more accurate in characterization of user interest, and better reflects the change of user interest, and efficiently improves the quality of network document resource personalized services. Finally the experiment describes the update process of the proposed model by using an example, and illustrates that the proposed model is simple and practical.
