Realizing Argumentation in Multi-agent Systems Using Defeasible Logic Programming

We describe a working multi-agent architecture based on Defeasible Logic Programming (DeLP) by Garcı́a and Simari where agents are engaged in an argumentation to reach a common conclusion. Due to the distributed approach personalities and opinions of the individual agents give rise to arguments and counterarguments concerning a particular query. We establish a sound theoretical framework of a specific type of argumentation in multi-agent systems and describe the computational issues involved in it. The framework described in this paper has been fully implemented and a short description of its features is given.
