Reputation and trust in the context of logic-based argumentation

Abstract

The specification of argument-based negotiation in e-Commerce environments aims not only at the definition of the best dealing strategies to be used by any set of computational entities in such environments, but also to mimic in its minds the reasoning processes of their human peers. Reputation may be one important parameter to be taken into account in the process of trust evaluation in a negotiation, once it can be analyzed either in terms of the quality of knowledge it carries into the negotiation process, or the referentials it may impose. In this work, such a model will be materialized by a sound syntactic and semantic tool for logic-based argumentation, where entities called agents and multiagent systems set the computational methodology to be pursued in the process of problem solving.
