摘要：Recommendation systems are widely used in Internet applications. In currentrecommendation systems, users only play a passive role and have limited control overthe recommendation generation process. As a result, there is often considerable

mismatch between the recommendations made by these systems and the actual userinterests, which are fine-grained and constantly evolving. With a user-powered distributedrecommendation architecture, individual users can flexibly define fine-grained

communities of interest in a declarative fashion and obtain recommendations accuratelytailored to their interests by aggregating opinions of users in such communities. Bycombining a progressive sampling technique with data perturbation methods, therecommendation system is both scalable and privacy-preserving.
