On the Role of Dialogue and Argumentation In Collaborative Problem Solving

In this paper, we make a first step towards a formal model of dialogue and argumentation for a multi-agent problem solving. We shall present a multi-agent system for problem solving. We shall the notion of collaborative problem solving and discuss some of the related communication issues. we propose a partial information state based framework for dialogue and argumentation. We shall employ a three-valued based nonmonotonic logic for representing and reasoning about partial information. We show via an example that the system can handle collaborative problem-solving tasks.
