Abstract

Our ambition in this paper is to begin to specify in argumentative terms (some of) the steps involved in a decision-aiding process. To do that, we make use of the popular notion of argument schemes, and specify the related critical questions. A hierarchical structure of argument schemes allows to decompose the process into several distinct steps---and for each of them the underlying premises are made explicit, which allows in turn to identify how these steps can be dialectically defeated via critical questions. This work initiates a systematic study which aims at constituting a significant step forward for forthcoming decision-aiding tools. The kind of system that we foresee and sketch here would allow: (i) to present a recommendation that can be explicitly justified; (ii) to revise any piece of reasoning involved in this process, and be informed of the consequences of such moves; and possibly (iii) to stimulate the client by generating contradictory arguments.
