Valid Attacks in Argumentation Frameworks with Recursive Attacks
The purpose of this work is to study a generalisation of Dung’s abstract argumentation frameworks that allows representing recursive attacks, that is, a class of attacks whose targets are other attacks. We do this by developing a theory of argumentation where the classic role of attacks in defeating arguments is replaced by a subset of them, which is extension dependent and which, intuitively, ...
متن کاملWeighted Attacks in Argumentation Frameworks
Recently, (Dunne et al. 2009; 2011) have suggested to weight attacks within Dung’s abstract argumentation frameworks, and introduced the concept of WAF (Weighted Argumentation Framework). However, they use WAFs in a very specific way for relaxing attacks. The aim of this paper is to explore ways to take advantage of attacks weights within an argumentation process. Two different approaches are c...
متن کاملEncompassing Attacks to Attacks in Abstract Argumentation Frameworks
In the traditional definition of Dung’s abstract argumentation framework (AF ), the notion of attack is understood as a relation between arguments, thus bounding attacks to start from and be directed to arguments. This paper introduces a generalized definition of abstract argumentation framework called AFRA (Argumentation Framework with Recursive Attacks), where an attack is allowed to be direc...
متن کاملAn Argumentation System with Indirect Attacks
We discuss argumentation frameworks with indirect attacks, such as why-questions and supports. A whyquestion is regarded as a kind of attack relation, and a support is an answer to an un-presented why-question. Based on this idea, we construct an argumentation framework with why-questions from a pair of knowledge bases, as an instantiation of Dung’s abstract argumentation framework, and show th...
متن کاملGeneralizing Abstract Argumentation with Nested Attacks
In this paper Dung’s abstract argumentation framework (cp. [23]) is being generalized by introducing nested attacks. Attacks are allowed not only on single arguments (e.g. a → b), but on the attacks themselves as well (a → (b → c)). Key terms of Dung’s account of abstract argumentation are adjusted for nested argumentation frameworks (henceforth NAF) in a way which preserves their original mean...
