متن کاملTowards an objective ranking in online reputation systems: the effect of the rating projection
Online reputation systems are commonly used by e-commerce providers nowadays. In order to generate an objective ranking of online items’ quality according to users’ ratings, many sophisticated algorithms have been proposed in the literature. In this paper, instead of proposing new algorithms we focus on a more fundamental problem: the rating projection. The basic idea is that even though the ra...
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...
