متن کاملA Unified Framework for Reputation Estimation in Online Rating Systems
Online rating systems are now ubiquitous due to the success of recommender systems. In such systems, users are allowed to rate the items (movies, songs, commodities) in a predefined range of values. The ratings collected can be used to infer users’ preferences as well as items’ intrinsic features, which are then matched to perform personalized recommendation. Most previous work focuses on impro...
