Abstract
The majority of approaches to abstract argumentation with fuzziness yield some number as part of the computation process, which is then compared to some threshold in order to determine which arguments should appear in an extension. However, identifying such a threshold is difficult, and a more natural approach therefore involves representing the extension as a fuzzy set of arguments. Such an approach was taken by Janssen's fuzzy argumentation frameworks, and in this paper we examine this framework, clarifying some of its definitions and adding some auxiliary notions which make the system more understandable and simplify the computation of extensions. Finally, we consider a specialization of the system by instantiating it with the Gödel t-norm min, and demonstrate that Janssen's framework is different from some fuzzy systems, such as the one proposed by de Costa Pereira et al.
