Maintaining sound reputation requires robust control and investigation. In this paper, we analyze a reputation mechanism that objectively maintains accurate reputation evaluation of selfish agent-based web services. In the proposed framework, web services are ranked using their reputation as result of provided feedback reflecting consumers’ satisfaction. However, selfish web services may alter ...

We then propose an infinite-horizon model, in which the fund’s reputation can be invested...

We present a new approach for computing reputation in agent societies. Our positional reputation system can handle arbitrary dimensions to provide a mapping of different attributes of an agent to its reputation value. The meaning of a certain dimension is not fixed, but is defined dynamically by the agent community. Thus a positional reputation system automatically adapts to the needs of the us...

In this paper, we describe how a large webmail service uses reputation to classify authenticated sending domains as either spammy or not spammy. Both SPF and DomainKey authentication are used to identify who the sender of the mail is. We describe a simple formula for how we calculate the reputation and how it is used to classify incoming mail. We show in general how domains, both good and bad, ...

Reputation systems take as input ratings from members in a community, and can produce measures of reputation, trustworthiness or reliability of entities in the same community. Binomial and multinomial Bayesian reputation systems are discrete in nature meaning that they normally take discrete ratings such as “average” or “good” as input. However, in many situations it is natural to provide input...

Maintaining a sound reputation mechanism requires a robust 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 feedback reflecting consumers’ satisfaction abou...
