Mechanisms for coping with unfair ratings and discriminatory behavior in online reputation reporting systems

Reputation reporting systems have emerged as an important risk management mechanism in online trading communities. However, the predictive value of these systems can be compromised in situations where conspiring buyers intentionally give unfair ratings to sellers or where sellers discriminate on the quality of service they provide to different buyers. This paper proposesa set of mechanisms that eliminate or significantly reduce the negative effects of such fraudulentbehavior. The proposedmechanismscan be easily integratedinto existing online reputation systems in order to safeguard their reliability in the presence of deceitful buyers and sellers.
