Abstract: Personalized web search is a promising way to improve search quality by customizing search results for people with individual information goals. However, users are uncomfortable with exposing private information to search engines. Thus, a balance must be struck between search quality and privacy protection. The proposed system presents a scalable way for users to automatically build rich user profiles. These profiles summarize user’s interests into a hierarchical organization according to specific interests. The system proposes a Personalized Web (PWS) framework called User customizable Privacy-preserving Search (UPS) that can adaptively generalize profiles by queries while respecting user specified privacy requirements. The 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 presents two greedy algorithms, namely Greedy DP and Greedy IL, for runtime generalization. It also provides an online prediction mechanism for deciding whether personalizing a query is beneficial.
