Instantiations and Computational Aspects of Non-Flat Assumption-based Argumentation
Tuomo Lehtonen, Anna Rapberger, Francesca Toni +2
Most existing computational tools for assumption-based argumentation (ABA) focus on so-called flat frameworks, disregarding the more general case. In this paper, we study an instan…
On the Correspondence of Non-flat Assumption-based Argumentation and Logic Programming with Negation as Failure in the Head
Anna Rapberger, Markus Ulbricht, Francesca Toni
The relation between (a fragment of) assumption-based argumentation (ABA) and logic programs (LPs) under stable model semantics is well-studied. However, for obtaining this relatio…
Understanding ProbLog as Probabilistic Argumentation
Francesca Toni, Nico Potyka, Markus Ulbricht +1
ProbLog is a popular probabilistic logic programming language/tool, widely used for applications requiring to deal with inherent uncertainties in structured domains. In this paper…
Rediscovering Argumentation Principles Utilizing Collective Attacks
Wolfgang Dvořák, Matthias König, Markus Ulbricht +1
Argumentation Frameworks (AFs) are a key formalism in AI research. Their semantics have been investigated in terms of principles, which define characteristic properties in order to…
