This work introduces the Attack-Support Argumentation Framework (ASAF), a novel approach to abstract argumentation extending the Argumentation Framework with Recursive Attacks (AFRA) in two ways. Firstly, it adds a support relation enabling to express support for arguments, for attacks, and for the support relation itself. Secondly, it extends AFRA´s attack relation allowing attacks to the support relation. Thus, the ASAF provides a unified framework for representing attack and support for arguments, as well as attack and support for the attack and support relations at any level.
