Ranking-based semantics received a lot of attention recently. All of the semantics introduced so far are applicable to binary attack relations. In this paper, we study a more general case when sets of arguments can jointly attack an argument. We generalise existing postulates for ranking-based semantics to fit this framework, define a general variant of h-categoriser, prove that it converges for every argumentation framework and study the postulates it satisfies. We also study the link between binary and hypergraph version of h-categoriser.</p>}, number={03}, journal={Proceedings of the AAAI Conference on Artificial Intelligence}, author={Yun, Bruno and Vesic, Srdjan and Croitoru, Madalina}, year={2020}, month={Apr.}, pages={3033-3040} }
