Sequence Explanations for Acceptance in Abstract Argumentation

We consider abstract argumentation and explanations for the

acceptance of arguments. Based on the notion of

serialisability, we introduce sequence explanations as a

procedural form of explanation for the acceptance of some

argument. Intuitively, these explanations represent the

process of accepting (and rejecting) arguments in order to

conclude the acceptance of a certain argument. We define

several variants of sequence explanations and examine them

in detail. In particular, we also incorporate

counterarguments into the explanations to make them

dialectical. Finally, we relate our explanations to other

approaches from the literature via a principle-based

analysis.
