Abstract
The web search engine has long become the most important portal for ordinary people looking for useful information on the web. However, 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. Personalized Web Search (PWS) is a general category of search techniques aiming at providing better search results, which are tailored for individual user needs. As the expense, user information has to be collected and analyzed to figure out the user intention behind the issued query. Personalized Web Search (PWS) has demonstrated its effectiveness in improving the quality of various search services on the Internet. However, evidences show that users’ reluctance to disclose their private information during search has become a major barrier for the wide proliferation of PWS. The proposed system studies privacy protection in PWS applications that model user preferences as hierarchical user profiles. This system modules proposes a PWS framework called UPS that can adaptively generalize profiles by queries while respecting user-specified privacy requirements. The proposed runtime generalization aims at striking a balance between two predictive metrics that evaluate the utility of personalization and the privacy risk of exposing the generalized profile. The system modules presents a greedy algorithm, namely GreedyIL, for runtime generalization. It also provides an online prediction mechanism for deciding whether personalizing a query is beneficial. The application used for simulation is designed using Microsoft Visual Studio .Net 2005 as front end. The coding language used is Visual C# .Net. MS-SQL Server 2000 is used as back end database.
