A meta-argumentation approach for the efficient computation of stable and preferred extensions in dynamic bipolar argumentation frameworks

摘要

Bipolar argumentation frameworks (BAFs) extend Dung's argumentation frameworks to explicitly represent the notion of support between arguments, in addition to that of attack. BAFs can be profitably used to model disputes between two or more agents, with the aim of deciding the sets of arguments that should be accepted to support a point of view in a discussion. However, since new arguments, attacks, and supports are often introduced to take into account new available knowledge, BAFs as well as the set of accepted arguments (under a given semantics) change over the time.
