Abstract Argumentation

Argumentation is one of the major fields in Artificial Intelligence (AI). Numerous applications in diverse domains like legal reasoning, multi-agent systems, social networks, e-government, decision support and many more make this topic very interdisciplinary and lead to a wide range of different formalizations.

Out of them the concept of abstract Argumentation Frameworks (AFs) is one of the most popular approaches to capture certain aspects of argumentation. This very simple yet expressive model has been introduced by Phan Minh Dung in 1995. Arguments and a binary attack relation between them, denoting conflicts, are the only components one needs for the representation of a wide range of problems and the reasoning therein.

Nowadays numerous semantics exist to solve the inherent conflicts between the arguments by selecting sets of “acceptable” arguments. Depending on the application, acceptability is defined in different ways.
