Argument Theory Change (ATC) applies classic belief change conceptsto the area of argumentation. This intersection of fields takes advantage of the definitionof a Dynamic Abstract Argumentation Framework, in which an argumentis either active or inactive, and only in the former case it is taken into considerationin the reasoning process. ATC identifies how the framework has to be modifiedin order to achieve warrant for a certain argument. The present article copeswith this matter by defining a revision operator based on activation of arguments,i.e., recognizing the knowledge that is missing.
