Personalized web Search Using User Profile

Personalized web search (PWS) used for improving the quality of various search services on the Internet. Users might experience failure when search engines return irrelevant results that do not meet their real intentions. Such irrelevance is largely due to the enormous variety of users' contexts and backgrounds, as well as the ambiguity of texts. However, evidences show that user's private information during search has become known to publicly due to proliferation of PWS. We propose a PWS framework called UPS that can adaptively generalize profiles by queries while respecting user specified privacy requirements.
