An introduction to argumentation semantics
The paper presents an extensive set of general properties for semantics evaluation and analyzes the notions of argument justification and skepticism, and discusses some relationships between semantics properties and domain-specific requirements. Expand
On principle-based evaluation of extension-based argumentation semantics
A set of general criteria for semantics evaluation is introduced by proposing a formal counterpart to several intuitive notions related to the concepts of maximality, defense, directionality, and skepticism. Expand
SCC-recursiveness: a general schema for argumentation semantics
This work proposes a general recursive schema for argumentation semantics, based on decomposition along the strongly connected components of the argumentation framework, and introduces four novel SCC-recursive semantics, able to overcome the limitations of preferred semantics, while differing in other respects.

AFRA: Argumentation framework with recursive attacks
This paper provides a complete development of the AFRA formalism complemented by illustrative examples and a detailed comparison with other recursive attack formalizations. Expand
Diagnosis of Large Active Systems
This paper presents a modular technique, amenable to parallel implementation, for the diagnosis of large-scale, distributed, asynchronous event-driven (namely, active) systems, which allows a modular and parallel exploitation of the reconstruction process. Expand
Semantics of Abstract Argument Systems
An abstract argument system or argumentation framework, as introduced in a seminal paper by Dung [13], is simply a pair 〈A ,R〉 consisting of a set A whose elements are called arguments and of aExpand
Encompassing Attacks to Attacks in Abstract Argumentation Frameworks
This paper introduces a generalized definition of abstract argumentation framework called $\ensuremath{AFRA}$ (Argumentation Framework with Recursive Attacks), where an attack is allowed to be directed towards another attack. Expand
On the resolution-based family of abstract argumentation semantics and its grounded instance
This paper analyzes the resolution-based version of the traditional grounded semantics, showing that it features the unique property of satisfying a set of general desirable properties recently introduced in the literature. Expand
Towards Artificial Argumentation
Recent developments in the field of computational models of argument are leading to technology for artificial argumentation, in the legal, medical, and e-government domains, and interesting tools for argument mining, for debating technologies, and for argumentation solvers are emerging. Expand
