COMMA, next week in Toulouse, is the largest gathering of computational folks interested in argumentation. The ARG Dundee group have two papers there, both involving the emerging Argument Interchange Format. The first deals with the link between AIF and argument visualisation, and the second with how dialogue can be richly represented with only very minor extensions to the initial AIF specification. We will also be showing an early alpha of Araucaria 4.0 which uses the AIF. It will be available for download after the conference.
