摘要：Online Reputation Systems are playing increasingly important roles in influencing people's online purchasing/downloading decisions. In this paper we propose a scheme user correlation algorithm. The existing mechanisms Time Domain Anomaly detection and Trust model based on dempster safer theory not provide better efficiency. First, limit the maximum number of ratings each user could provide with in the certain time duration. Second investigating users rating behaviors by building user trust, such as a personalized trust model, which evaluates a user's judging power as the inverse of this user's rating variance. In the proposed system, jointly consider trust evaluation and user correlation. Correlation is calculated based on already defined malicious users. Based on the user correlated relationship values eliminate the time consuming and low efficiency.
