Dung's argumentation frameworks have been applied for over twenty years to the analysis of argument justification. This representation focuses on arguments and the attacks among them, abstracting away from other features ...

Argumentation frameworks often model dynamic situations where arguments and their relationships (e.g., attacks) frequently change over time. As a consequence, the sets of conclusions (e.g., extensions of abstract argumentation ...

To increase the expressivity of an argumentation formalism, we propose adding meta-level information to the arguments in the form of labels representing quantifiable data such as reliability degree, strength measure, skill, ...

An essential part of argumentation-based reasoning is to identify arguments in favor and against a statement or query, select the acceptable ones, and then determine whether or not the original statement should be accepted. ...

We propose a new family of abstract argumentation frameworks which we refer to as generalized (identified through the acronym GenAF), due to its ability of adapting to different representation languages. GenAFs are formalized ...

This paper presents some contributions of argumentative semantics to the study of the functioning of the perfecto simple (PPS) and compuesto (PPC) in Spanish. With this purpose, we discuss how this discipline conceives the ...

This work introduces the Attack-Support Argumentation Framework (ASAF), an approach to abstract argumentation that allows for the representation and combination of attack and support relations. This framework extends the  ...
