Guest Editorial: The Agent Reputation and Trust (ART) Testbed

Abstract

Computational trust and reputation models have been recognized as one of the main topics in the area of autonomous agents and multiagent systems. Whenever you have a complex society you need control mechanisms to ensure that the behaviour of the individuals follows certain conventions. In open virtual societies and similar to what happens in real human societies, on top of low level security measures (network security layer) and the control exerted by virtual institutions (institutional layer), there is still a need for an extra layer based on the individuals. In this layer, that can be called “social control layer”, is where we find the computational trust and reputation models.
