| Abstract: | A method to generate dynamic user profiles for personalization in web resource search was described. Access record based user profiles were stored by the RDF to take the advantage of semantic express ability for user profiles optimizing, and users were clustered to several user community to effectively manage user profiles.Algorithms for meta-search engine selecting and search results sorting were provided for personalized meta-search engine implementation.Test results show that this search engine can not only promote searching efficiency and precise ratio, but also reorganize searching results according to user＇s community profiles. |
