Simulating Argumentation about Exchange Values in Multi-agent Interactions

This article presents two dialogue protocols to support argumentation about the exchange values involved in multi-agent interactions. In this work, we adopt Piaget´s theory of social exchanges, where interaction is seen as an exchange of services between agents, such that the agents assign subjective, qualitative values - called exchange values - to the actions and objects that they exchange during the interaction. The protocols enable the agents to argue with each other about the exchange values. The agents present characteristics related to the social power and personality traits. We show how these characteristics are considered in the reasoning of the agents, and how it can influence the actions of the agents during the interactions.
