摘要： User interest model is an important part of distance personalized learning, which is also the core and foundation. A good user model can reflect the preference information accurate and comprehensive, which can obtain user preference characteristics information and can reflect the real characteristics and requirements effectively. User interest model can guide users to obtain information which is in line with the characteristics of their own interest, so that the information can be more active. The construction of user interest model generally includes information collection, user interest model representation, model learning and updating. A personalized user interest model based on user attribute information and learning resources domain ontology is researched and constructed for the prediction of user behavior changes is inaccurate, algorithm space complexity is high, the analysis of the user behavior impact is not accurate and comprehensive. At last, the calculation method of model concept interest degree is researched and given.
