| Abstract: | With the rapid development of Internet,the number of accessible web page has been exponential growth on the Internet.It has become increasingly difficult for users to find information satisfied with their individual needs.In this paper,a vector-based model was presented and described by a hierarchy tree,in which the user preferences(profiles) were defined.The constructed user profile could be used to adapt the user's query result to one's need.Furthermore,an adjusting algorithm for user profile was presented.Simulation tests prove that the precision of the returned web pages is effectively improved. |
