In order to improve the level of personalized service and enhance accuracy of search, it is necessary to build user model in e-learning system.This paper provided a user model expressed semantic relation tree. Algorithms for the vector space model and the least frequently used(LRU) introduced into the model were used to periodically update the co-adjustment model.Using the established model can effectively improve search accuracy,and the model can effectively support personalized service.The simulation test showed this model was effective.
