[en] This work explores the revival of arguments in abstract argumentation theory. A revived argument is an argument that is put forward in a specific context, but is somehow put aside because it did not seem relevant to the discussion or it has been denied, and then becomes useful in another context when a similar argument emerges. We obtain necessary conditions for argument revival using real-world examples and show that a recently proposed temporal argumentation framework cannot account for argument revival. Next, we propose an algorithm for argument revival that uses arguments annotated by a context label. This algorithm determines what arguments can be revived using the context neighborhood, the attack relations and a revival policy.
