On the Reputation of Agent-Based Web Services.
Maintaining a sound reputation mechanism requires a ro bust control and investigation. In this paper, we propose a game-theoretic analysis of a reputation mechanism that objectively maintains accurate reputation evaluation of selfish agent-based web services. In this framework, web services are ranked using their reputation as a result of provided feed back reflecting consumers' satisfaction about the of fered ser vices. However, selfish web services may alter their public reputation level by managing to get fake feedback. In this paper, game-theoretic analysis investigates the payof fs of dif ferent situations and elaborates on the facts that discourage web services to act maliciously.
