Forgetting aspects in assumption-based argumentation
M Berthold, A Rapberger… - Proceedings of the …, 2023 - proceedings.kr.org
We address the issue of forgetting in assumption-based argumentation (ABA). Forgetting is
driven by the goal to remove certain elements from a knowledge base, while preserving the …

Relating abstract and structured accounts of argumentation dynamics: the case of expansions
H Prakken - Proceedings of the International Conference on …, 2023 - proceedings.kr.org
This paper proposes a structured variant in ASPIC+ of the notion of expansions of abstract
argumentation frameworks. The purpose of this is threefold: studying what it takes to …

On the expressive power of assumption-based argumentation
The expressiveness of any given formalism lays the theoretical foundation for more
specialized topics such as investigating dynamic reasoning environments. The modeling …

[HTML][HTML] A claim-centric perspective on abstract argumentation semantics: Claim-defeat, principles, and expressiveness
W Dvořák, A Rapberger, S Woltran - Artificial Intelligence, 2023 - Elsevier
Dung's abstract argumentation frameworks (AFs) are a key formalism in AI research
nowadays. Claims are an inherent part of each argument; they substantially determine the …

[HTML][HTML] An abstract and structured account of dialectical argument strength
H Prakken - Artificial Intelligence, 2024 - Elsevier
This paper presents a formal model of dialectical argument strength in terms of the number
of ways in which an argument can be successfully attacked in expansions of an abstract …

Attack semantics and collective attacks revisited
In the current paper we re-examine the concepts of attack semantics and collective attacks in
abstract argumentation, and examine how these concepts interact with each other. For this …
