Dialogue Games for Enforcement of Argument Acceptance and Rejection via Attack Removal

Argumentation is dynamic in nature and most commonly exists in dialogical form between different agents trying to convince each other. While abstract argumentation framework are mostly static, many studies have focused on dynamical aspects and changes to these static frameworks. An important problem is the one of argument enforcement, modifying an argumentation framework in order to ensure that a certain argument is accepted. In this paper, we use dialogue games to provide an exhaustive list of minimal sets of attacks such that when removed, a given argument is credulously accepted with respect to preferred semantics. We then extend the method to enforce other acceptability statuses and cope with sets of arguments.
