English abstract:
A common feature of non-monotonic logics is that the classical
notion of equivalence does not preserve the intended
meaning in light of additional information. Consequently,
the term strong equivalence was coined in the literature and
thoroughly investigated. In the present paper, the knowledge
representation formalism under consideration are claimaugmented
argumentation frameworks (CAFs) which provide
a formal basis to analyze conclusion-oriented problems in argumentation
by adapting a claim-focused perspective. CAFs
extend Dung AFs by associating a claim to each argument
representing its conclusion. In this paper, we investigate both
ordinary and strong equivalence in CAFs. Thereby, we take
the fact into account that one might either be interested in the
actual arguments or their claims only. The former point of
view naturally yields an extension of strong equivalence for
AFs to the claim-based setting while the latter gives rise to
a novel equivalence notion which is genuine for CAFs. We
tailor, examine and compare these notions and obtain a comprehensive
study of this matter for CAFs. We conclude by
investigating the computational
