Modelling time and reliability in structured argumentation frameworks

Abstract

Argumentation is a human-like reasoning mechanism con-tributing to the formalization of commonsense reasoning. In the last decade, several argument-based formalisms have emerged, with application in many areas, such as legal rea-soning, autonomous agents and multi-agent systems; many Argumentation Frameworks (AF). Recent research in the area has led to Temporal Argumentation Frameworks (TAF) that extend Dung’s by considering the temporal availability of ar-guments. In this work we introduce a novel framework, called Extended Temporal Argumentation Framework (E-TAF), ex-tending TAF with the capability of modeling availability of attacks among arguments, which allows for instance to model reliability of arguments varying over time. We show how Argumentation, adding compositional elements to the ab-stract arguments involved based on a simplified version of the recently introduced Dynamic Argumentation Frameworks. 1
