An argumentation framework is a formal structure for representing arguments and the conflicts between them in order to reason about contested information. In abstract frameworks, arguments are nodes in a directed graph and attack relationships are edges. Such frameworks support automated reasoning about which arguments can be accepted under defined semantics.
(Also argumentation system.) A way to deal with contentious information and draw conclusions from it. In an abstract argumentation framework, entry-level information is a set of abstract arguments that, for instance, represent data or a proposition. Conflicts between arguments are represented by a binary relation on the set of arguments. In concrete terms, you represent an argumentation framework with a directed graph such that the nodes are the arguments, and the arrows represent the attack relation. There exist some extensions of the Dung's framework, like the logic-based argumentation frame
