Within the last decade, abstract argumentation has emerged as a central field in Artificial
Intelligence. Besides providing a core formalism for many advanced argumentation systems …

The study of multi-agent systems (MAS) focuses on systems in which many intelligent agents
interact with each other. These agents are considered to be autonomous entities such as …

Over the last ten years, argumentation has come to be increasingly central as a core study
within Artificial Intelligence (AI). The articles forming this volume reflect a variety of important …

In many cases of disagreement, particularly in situations involving practical reasoning, it is
impossible to demonstrate conclusively that either party is wrong. The role of argument in …

Wolfgang Dvorák, Paul E. Dunne abstract. In this chapter we give an overview of the core
computational problems arising in formal argumentation together with a complexity analysis …

We introduce and investigate a natural extension of Dung's well-known model of argument
systems in which attacks are associated with a weight, indicating the relative strength of the …

In this paper we introduce dialectical frameworks, a powerful generalization of Dung-style
argumentation frameworks where each node comes with an associated acceptance …

Abstract argumentation frameworks (AFs), originally proposed by Dung, constitute a central
formal model for the study of computational aspects of argumentation in AI. Credulous and …

In this paper, we examine an argument-based semantics called semi-stable semantics.
Semi-stable semantics is quite close to traditional stable semantics in the sense that every …
