Within the last decade, abstract argumentation has emerged as a central field in Artificial
Intelligence. Besides providing a core formalism for many advanced argumentation systems …

Chatbots are conversational software applications designed to interact dialectically with
users for a plethora of different purposes. Surprisingly, these colloquial agents have only …

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 …

Abstract argumentation frameworks (AFs) provide the basis for various reasoning problems
in the area of Artificial Intelligence. Efficient evaluation of AFs has thus been identified as an …

We discuss the value of argumentation in reaching agreements, based on its capability for
dealing with conflicts and uncertainty. Logic-based models of argumentation have recently …

In this paper we present the computational model of Arg 2 P, a logic-based argumentation
framework for defeasible reasoning and agent conversation particularly suitable for …

We test different solvers dedicated to the solution of classical problems in Abstract
Argumentation, as enumeration/existence of extensions, and sceptical/credulous …

We introduce an argument-based discussion game where the ability to win the game for a
particular argument coincides with the argument being in the grounded extension. Our game …

Argumentation is a well-studied formal model for multiagent interaction that supports
exchange of information about agents' beliefs and reasons why agents hold their beliefs. We …
