This paper adopts the method of building user modeling and domain Ontology approach, and extracts the user information through studying and analyzing the user search history. Then the user modeling that consists of user Ontology and user concept vectors is constructed. The experiment shows that this study improves the order of the user retrieval results.

Key wordsUser modeling      Ontology      TF×IDF
