This article analyzes the users relevance and its influence on the users' satisfaction. It points out the functions of users modeling which can be used to record the personalized information and do modeling based learning and reasoning to find out the preference of users,and places an emphasis on users modeling during the process of information retrieval. It discusses the characteristic of users information requirements and addresses how to build the users modeling and realize the users' demands learning. Finally it gives a brief appraisal on the application of users modeling in the field of personalized information retrieval, also includes the difficulties.
