Defining new argumentation-based semantics by minimal models

Dung´s argumentation approach is a unifying approach which has played an influential role on argumentation research and artificial intelligence (AT). Based on a proper representation of Dung´s argumentation approach and minimal models, we introduce a novel argumentation semantics called preferred⁺ semantics which follows the preferred semantics´ philosophy. Also, we show how to infer preferred⁺ semantics using a software tool called SI-COBRA that was introduced recently
