A Tracking Algorithm

In this paper, we propose a biclustering-based approach to iden-tify dishonest advisors (who provide misleading opinions about sellers), while evaluating seller trustworthiness on multiple crite-ria. It considers correlation between advisors ’ ratings to various criteria and trust transitivity to accurately filter the dishonest advi-sors. Evaluation results demonstrate the robustness of our approach against various types of unfair rating attacks
