147 Enhanced Reputation Model with Forgiveness for E-Business Agents Radu Burete University of Craiova, Romania Amelia Bdic University of Craiova, Romania Costin Bdic University of Craiova, Romania Florin Moraru University of Craiova, Romania Chapter 10 ABSTRACT Trust is a very important quality attribute of an e-service. In particular, the increasing complexity of the e-business environment requires the development of new computational models of trust and reputation for e-business agents. In this paper, the authors introduce a new reputation model for agents engaged in e-business transactions. The model enhances classic reputation models by the addition of forgiveness factor and the use of new sources of reputation information based on agents groups. The paper proposes an improvement of this model by employing the recent con-resistance concept. Finally, the authors show how the model can be used in an agent-based market environment where trusted buyer and seller agents meet, negotiate, and transact multi-issue e-business contracts. The system was implemented using JADE multi-agent platform and initially evaluated on a sample set of scenarios. The paper introduces the design and implementation of the agent-based system together with the experimental scenarios and results. DOI: 10.4018/978-1-4666-1565-6.ch010 Copyright © 2012, IGI Global.
