Abstract

This paper describes a Group Decision and Negotiation Support System for cooperative or non-cooperative argumentative discourses. The system provides agents means of expressing and weighing their individual arguments and preferences, the aim being the selection of a certain choice. It also supports defeasible and qualitative reasoning in the presence of ill-structured information. Argumentation is performed through a set of discourse acts which call a variety of procedures for the propagation of information in the corresponding discussion graph.
