Abstract

Collaborative sites like Wikipedia allow the public to contribute contents to a particular domain to ensure a site's growth. However, a major concern with such sites is the credibility of the information posted. Malicious and "lazy" authors can intentionally or accidentally contribute entries that are inaccurate. This paper presents a user-driven reputation system called Rater Rating that encourages authors to review entries in collaborative sites. It uses concepts adopted from reputation systems in mobile ad-hoc networks (MANETs) that promotes cooperation among network nodes. Rater Rating measures the overall reputation of authors based on the quality of their contribution and the "seriousness" of their ratings. Simulations were performed to verify the algorithm's potential in measuring the credibility of ratings made by various raters (i.e. good and lazy). The results show that only 1 out of 4 raters is needed to be a good rater in order to make the algorithm effective.
