This paper presents a conceptbased personalized information retrieval model in digital library which uses many technologies including vector space, Agent and Web log file mining. This model builds the conceptbased user interest profile according to the information provided initiatively by the user, updates the user interest profile according to the user’s interest information explicitly and the user’s implicit feedback which is obtained by observing the user action when the user visits the digital library. This model can use the user interest profile in queuing the search result by correlation degree,recommending the latest information to the user and collaboration-based recommending.At last a method of system realization is proposed.

Key wordsDigital library      Personalized information retrieval      User interest profile
