Talk by Jeremy Dauphin on argumentation theory: "A dynamic approach for combining abstract argumentation semantics"

Abstract argumentation semantics provide a direct relation from an argumentation framework to corresponding sets of acceptable arguments, or equivalently to labeling functions. Instead, we study step-wise update relations on argumentation frameworks whose fixpoints represent the labeling functions on the arguments. This dynamic generalization is used to study the combination of abstract argumentation semantics. We identify different orders of granularity between update relations with the same reachable fixpoints, and provide a formal definition of the most granular update relation for a given direct semantics. We focus also on a particular case where the combination of two update relations for different direct semantics leads to an update relation for a third direct semantics.
