This work will introduce a novel combination of two important argumentation related notions. We will start from the well-known basis of
Abstract Argumentation Frameworks
or
AFs
, and we will build a new formalism in which the notions corresponding to Toulmin’s backings and Pollock’s undercutting defeaters are considered. The resulting system,
Backing-Undercutting Argumentation Frameworks
or
BUAFs
, will be an extension of the
AFs
that includes a specialized support relation, a distinction between different attack types, and a preference relation among arguments. Thus,
BUAFs
will provide a richer representation tool for handling scenarios where information can be attacked and supported.
