Abstract

In this paper it is shown how communication about trust in a multi-agent system may be used to endow agents with belief change capabilities, in a probabilistic logical framework. Belief change operators are obtained in an intuitive, principled way using aggregation operators for trust-values. Under additional conditions, such change operators may be proved to be maxichoice. The present approach constitutes a sound method for autonomous uncertainty management in multi-agent systems.
