A Discussion Game for the Grounded Semantics of Abstract Dialectical Frameworks

Atefeh Keshavarzi Zafarghandi, Rineke Verbrugge, Bart Verheij

Abstract dialectical frameworks (ADFs) have been introduced as formalism for the modeling and evaluating argumentation. However, the role of discussion in evaluating of arguments in ADFs has not been clarified well so far. We focus on the grounded semantics of ADFs and provide the grounded discussion game. We show that an argument is acceptable (deniable) in the grounded interpretation of an ADF without any redundant links if and only if the proponent of a claim has a winning strategy in the grounded discussion game.
