Relational Argumentation Semantics

TL;DR

This paper introduces a novel relational perspective on argumentation semantics, framing them as relational databases to unify various existing semantics under a common formal language.

Contribution

It proposes the concept of relational argumentation semantics, providing a unified framework to understand diverse argumentation semantics through a relational database approach.

Findings

Many existing semantics are interpretable within the relational perspective

Relational argumentation semantics encapsulate argumentation graphs effectively

The approach unifies explanation, multi-agent, and traditional semantics

Abstract

In this paper, we propose a fresh perspective on argumentation semantics, to view them as a relational database. It offers encapsulation of the underlying argumentation graph, and allows us to understand argumentation semantics under a single, relational perspective, leading to the concept of relational argumentation semantics. This is a direction to understand argumentation semantics through a common formal language. We show that many existing semantics such as explanation semantics, multi-agent semantics, and more typical semantics, that have been proposed for specific purposes, are understood in the relational perspective.
