Abstract

The study of trust management in multi-agent system, especially dis- tributed, has grown over the last years. Trust is a complex subject that has no general consensus in lit- erature, but has emerged the impor- tance of reasoning about it computa- tionally. Reputation systems takes into consideration the history of an entity's actions/behavior in order to compute trust, collecting and aggre- gating ratings from members in a community. In this scenario the ag- gregation problem becomes funda- mental, in particular depending on the environment. In this paper we describe a technique based on a class of asymptotically idempotent aggre- gation operators, suitable particu- lary for distributed anonymous en- vironments.
