Abstract

We study here the behaviour of a trust and reputation model for agents in P2P environment, where agents act as providers or consumers of resources. We present partial results of the refinement process of our model in order to identify the suitable structure, functions, and parameters to correctly manage trust and reputation. We show some experimental results comparing several alternatives to obtain the quality of the response given the requirements, and the increase of the satisfaction of the recommended response when it uses a right way to estimate trust and reputation values using stored information about similar tasks.
