Acceptability semantics accounting for strength of attacks in argumentation
Claudette Cayrol, Caroline Devred, Marie-Christine Lagasquie-Schiex · Frontiers in artificial intelligence and applications · 2010
We consider argumentation systems with several attack relations of different strength. We focus on the impact of various strength attacks on the semantics of such systems. First, we refine the classical notion of defence, by comparing the strength of an attack with the strength of a counter-attack. Then, we propose different ways to compare defenders, and sets of defenders. That enables us to define admissible sets offering a best defence for their elements.
