Research on Trust Framework in Multi-Agent System from the Cognitive View

From the cognitive view,this paper proposes a framework of establishing trust in a proactive manner.In the framework the definition of trust in the situation of delegation and non-delegation are distinguished,the agent as trustor establishes a reasoning process of trust based on the definition of trust.And then he takes initiative to request information which is needed in the reasoning process from the trustee.Considering the reliability of information in communication,the trustor conduct on a fuzzy reasoning process on the basis of cognitive reasoning after information received.The framework especially aims at the situation that the trustor has no experience of interaction with the trustee,and has no witness information about the trustee.With this framework,trust between agents can be established in a proactive manner.Context change can also be taken into consideration in the establishment of trust.Furthermore,the framework brings more flexibility on establishment of trust,as agent can use different inference rules in different context.
