Implementation of argumentation semantics through argument games

This paper focuses on the argumentation semantics for preference-based decision problem. Based on the preference-decoupling framework, a new argument game composed by a series of two-party dialogues is proposed to realize the extension semantics. Two agents, the Master and Challenger, hold an argument each to perform a dialogue game by attacking each other. Winner of a dialogue game will present his arguments into the extension set. The complete extension set can be generated by continuously developing new dialogues in the remained arguments, till there are no new topics for dialogue. The proposed scheme can achieve the same result as the conventional scheme while saving computation complexity. The superiority is more obvious when arguments update happens, as only part of the argument game will be redone. Demonstration is presented to validate the scheme.
