Modeling and evaluation of trusts in Multi-agent systems

Abstract

Based on the existing trust evaluation mechanisms, we proposed a novel mechanism to help agents evaluate the trust value of the target agent in the multi-agent systems. We present an approach to help agents construct a trust network automatically in a multi-agent system. After the construction of the trust network, we use the Bayesian Inference Propagation approach with Leaky Noisy-Or model to solve the trust graph.The experiments carried out by our simulation work demonstrate that our model works better than the models proposed by other authors.
