A Tool For Ranking Arguments Through Voting-Games Power Indexes

Abstract Argumentation Frameworks allow to represent sets of arguments, together with possible relations among them, in form of oriented graphs. This paper gives a short overview of a plug-in function developed for ConArg, a solver of Abstract Argumentation related problems. The web-based tool we present computes a ranking of arguments by applying different voting games power indexes, where the coalitions of individuals are defined by the extensions satisfying Dung’s semantics. At this stage of development, the tool can make use of both the Shapley Value and the Banzhaf Index.
