The rapid development of information makes our work and life convenient,at the same time it brings us the problem of "information overload",which could be effectively solved by personalized infor-mation service. The user preference model is the basis and core of personalized information service,and its quality directly decides the quality of personalized information service. Based on the connotation and core content of the user preference model,the acquisition of user preference information,the representation of user preference,and the algorithm of model building,this paper discusses the advantages and disadvantages of the model and indicates its future research direction.
