On the Equivalence Between Abstract Dialectical Frameworks and Logic Programs

Abstract: Dialectical Frameworks (ADFs) are argumentation frameworks where each node is associated with an acceptance condition. This allows us to model different types of dependencies as supports and attacks. Previous studies provided a translation from Normal Logic Programs (NLPs) to ADFs and proved the stable models semantics for a normal logic program has an equivalent semantics to that of the corresponding ADF. However, these studies failed in identifying a semantics for ADFs equivalent to a three-valued semantics … Show more

“…What Table 3 and Table 4 in essence show is in which case doing a particular selection on the argument level yields the same result as doing a comparable selection on the conclusion level. Our findings should also benefit some similar investigations exploring semantic correspondences between logic programming semantics and other argumentation formalisms, such as [1,36,37,42].…”

“…We round off with a discussion of the obtained results and an overview of the overall correspondences and non-correspondences between argumentation semantics and logic programming semantics in Section 6. 1 The first two correspondences are also observed in [24], though in a different way.…”

“…The main acceptability semantics 1 of Dung AFs are defined as follows: Definition 2.3 (Acceptability semantics). Let H = A, R be an AF and E ⊆ A. E is a complete extension iff it is admissible and contains all the elements it defends (i.e., F H (E) = E); E is the grounded extension iff it is the ⊆-minimal complete extension; E is a preferred extension iff it is a ⊆-maximal complete extension; E is a stable extension iff it is conflict-free and attacks all the arguments outside it (i.e.,…”

“…In particular, the semantic equivalence between complete extensions in AF and 3-valued stable models in LP was first established in (Wu et al 2009). Then, the relationships of LP with AF have been further studied in (Caminada et al 2015), whereas those with Assumption-Based Argumentation (Bondarenko et al 1997;Craven and Toni 2016) have been considered in (Caminada and Schulz 2017), and those with Abstract Dialectical Frameworks have been investigated in (Alcântara et al 2019). Efficient mappings from AF to Answer Set Programming (i.e.…”
