|The rating system is the key for the success of the emerging Web 2.0 systems in that not only does it help the audience identify the merit of each Web 2.0 document, but it also provides incentives for participants to continue contributing to the system. However, the reliability of the rating system is vulnerable when there are uncooperative users in the system (e.g., bad mouthing or ballot stuffing). Tackling this issue, we in this paper propose a simple yet practical solution for Web 2.0-based rating systems. More precisely, in addition to aggregating rating results from all reviewers, the proposed scheme also takes into account the trustiness of each user while aggregating, and thereby significantly improves the overall reliability of the rating system.
