Argument Theory Change: Revision Upon Warrant

Abstract. We propose an abstract argumentation theory whose dynamics is captured by the application of belief revision concepts. The theory is deemed as abstract because both the underlying logic for arguments and argumentative semantics remain unspecified. Regarding our approach to argument theory change, we define some basic change operations along with their necessary theoretical elements towards the definition of a warrant-prioritized revision operation. This kind of revision expands the theory by an argument and then applies a contraction ensuring that the added argument can be believed afterwards. .
