Collective Argumentation

TL;DR

This paper introduces collective argumentation, an extension of abstract argumentation frameworks where attacks are among sets of arguments, enhancing the representation of disjunctive logic program semantics and allowing shared arguments among opponents.

Contribution

It presents a novel collective argumentation framework with attack relations among argument sets, improving modeling of disjunctive logic semantics and sharing mechanisms.

Findings

Suitable for representing disjunctive logic program semantics

Includes two types with shared arguments among opponents

Extends abstract argumentation frameworks

Abstract

An extension of an abstract argumentation framework, called collective argumentation, is introduced in which the attack relation is defined directly among sets of arguments. The extension turns out to be suitable, in particular, for representing semantics of disjunctive logic programs. Two special kinds of collective argumentation are considered in which the opponents can share their arguments.
