On the Complexity of the Discussion-based Semantics in Abstract Argumentation
Lydia Blümel, Kai Sauerwald, Kenneth Skiba +1
We show that deciding whether an argument a is stronger than an argument b with respect to the discussion-based semantics of Amgoud and Ben-Naim is decidable in polynomial time. At…
Axiomatics of Restricted Choices by Linear Orders of Sets with Minimum as Fallback
Kai Sauerwald, Kenneth Skiba, Eduardo Fermé +1
We study how linear orders can be employed to realise choice functions for which the set of potential choices is restricted, i.e., the possible choice is not possible among the ful…
Extension-ranking Semantics for Abstract Argumentation Preprint
Kenneth Skiba, Tjitze Rienstra, Matthias Thimm +2
In this paper, we present a general framework for ranking sets of arguments in abstract argumentation based on their plausibility of acceptance. We present a generalisation of Dung…
An Extension-Based Argument-Ranking Semantics: Social Rankings in Abstract Argumentation Long Version
Lars Bengel, Giovanni Buraglio, Jan Maly +1
In this paper, we introduce a new family of argument-ranking semantics which can be seen as a refinement of the classification of arguments into skeptically accepted, credulously a…
