Argumentation can be modelled at an abstract level using a directed graph where each
node denotes an argument and each arc denotes an attack by one argument on another …

Social media is flooded with rumors, which make fake news detection a pressing problem.
Many black-box approaches have been proposed to automatically predict the veracity of …

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 …

The paper studies semantics that evaluate arguments in argumentation graphs, where each
argument has a basic strength, and may be attacked by other arguments. It starts by defining …

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 …

Abstract Dung's Argumentation Framework (AF) has been extended in several directions,
including the possibility of representing uncertainty about the existence of arguments and …

Federico Cerutti, Sarah A. Gaggl, Matthias Thimm, Johannes P. Wallner abstract. We survey
the current state of the art of general techniques, as well as specific software systems for …

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 …

Abstract Dung's Argumentation Framework (AF) has been extended in several directions,
including the possibility of representing unquantified uncertainty about the existence of …
