A formal account of complex argumentation in a critical discussion

In this paper, I present a dialogue game approach to the argumentation stage of a critical discussion. This formal perspective on the pragma-dialectical ideal model is meant to facilitate a contribution of pragma-dialectical theorising to the field of argumentation and computation. The dialogue game is based on the technical rules for a critical discussion that relate to the argumentation stage, and I will show how sequences of moves in the dialogue game relate to complex argumentation structures.
