Semantics of Argumentation
Abstract
In this chapter, we introduce two approaches for defining the semantics of an abstract argumentation framework: extension-based approach and labelling-based approach. The idea underlying the extension-based approach is to identify sets of arguments, called extensions, that can be regarded as collectively acceptable according to some criterion. The idea underlying the labelling-based approach is to assign a label to each argument, according to a certain criterion. It has been verified that under most of argumentation semantics, there exists a bijective correspondence between sets of extensions and a set of labellings of an argumentation framework.
