This paper describes HERMES,a system that enhances group decision making by providing an argumentation frameworkto the agents involved. Thesystem organizes the existing knowledgein a discussion graph, whichconsists of issues, alternatives, positions and preference relations. Argumentation is performed through a set of discourse acts which trigger appropriate procedures for the propagation of information in the graph. HEaMESis able to handle incomplete, qualitative and inconsistent information, and provides mechanisms for weighing arguments.
