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 …

Abstract Argumentation is a process of evaluating and comparing a set of arguments. A way
to compare them consists in using a ranking-based semantics which rank-order arguments …

In this paper we take a step towards using Argumentation in Social Networks and introduce
Social Abstract Argumentation Frameworks, an extension of Dung's Abstract Argumentation …

This paper presents a novel argumentation framework to support Issue-Based Information
System style debates on design alternatives, by providing an automatic quantitative …

Classical semantics for abstract argumentation frameworks are usually defined in terms of
extensions or, more recently, labelings. That is, an argument is either regarded as accepted …

In this paper, we address the problem of change in an abstract argumentation system. We
focus on a particular change: the addition of a new argument which interacts with previous …

The study of properties of gradual evaluation methods in argumentation has received
increasing attention in recent years, with studies devoted to various classes of …

An argumentation framework is a pair made of a graph and a semantics. The nodes and the
edges of the graph represent respectively arguments and relations (eg, attacks, supports) …

Abstract argumentation offers an appealing way of representing and evaluating arguments
and counterarguments. This approach can be enhanced by considering probability …
