This paper introduces the Higher-Order Quadripolar Argumentation Framework (HQAF), which extends bipolar frameworks by allowing attacks and three types of supports---necessary, deductive, and evidential---to interact at higher order. In HQAF, each interaction may have as its source and target an argument, an attack, or...

Evidential-Based Higher-Order Set Argumentation Framework

Evidential argumentation extends Dung's abstract argumentation by requiring arguments and interactions to be backed by chains of evidence rooted in prima-facie elements. However, existing formalisms lack a unified treatment of evidential support, higher-order relations (attacks and supports targeting arbitrary elements...

The Evidential-Based Higher-Order Set Argumentation Framework is introduced, which conservatively generalises several existing frameworks within a single expressive setting and unifies expressive argumentation with principled three-valued and fuzzy semantics, bridging the gap between qualitative and quantitative reason...
