Computing Extensions of Dynamic Abstract Argumentation Frameworks with Second-Order Attacks
Gianvincenzo Alfano, Sergio Greco, Francesco Parisi · 2018
Extended argumentation frameworks (EAFs) extend Dung's argumentation frameworks (AFs) to represent a kind of defeasible attack (by relying on the concept of second-order attack), in addition to the Dung's classical notion of attack between arguments. EAFs can be profitably used to model disputes between agents, with the aim of deciding the sets of arguments (called extensions) that should be accepted to support a point of view in a discussion. However, since new arguments and attacks are often introduced to take into account new available knowledge, EAFs as well as their extensions change over the time.
