FIRE: An Integrated Trust and Reputation Model for Open Multi-Agent Systems

Trung Dong Huynh, Nicholas R. Jennings, Nigel R. Shadbolt

Trust and reputation are central to effective interactions in open multi-agent systems in which agents, that are owned by a variety of stakeholders, can enter and leave the system at any time. This openness means existing trust and reputation models are cannot readily be used. To this end, we present FIRE, a trust and reputation model that integrates a number of sources to produce a comprehensive assessment of an agent's likely performance. Specifically, FIRE incorporates interaction trust, role-based trust, witness reputation, and certified reputation to provide a trust metric in virtually all circumstances. FIRE is empirically benchmarked and is shown to help agents effectively select appropriate interaction partners.
