A structural benchmark for logical argumentation frameworks

This paper proposes a practically-oriented benchmark suite for computational argumentation. We instantiate abstract argumentation frameworks with existential rules, a language widely used in Semantic Web applications and provide a generator of such instantiated graphs. We analyse performance of argumentation solvers on these benchmarks.

Arguing About End-of-Life of Packagings: Preferences to the Rescue

Argumentation methods and associated tools permit to analyze arguments against or in favor of a set of alternatives under discussion. The outputs of the argument methods are sets of conflict-free arguments collectively defending each other, called extensions. In case of multiple extensions, it is often difficult to select one out of many alternatives. We present in this paper the implementation of an complementary approach which permits to filter or rank extensions according to the expression of preferences. Methods and tools are illustrated on a real use case in food packagings. The aim is to help the industry choose among different end-of-life possibilities by linking together consumer behavior insights, socioeconomic developments and technical properties of packagings. The tool has been used on a real use-case concerning end-of-life possibilities for packag-ings.

Inconsistency Measures for Repair Semantics in OBDA

In this paper, we place ourselves in the Ontology Based Data Access (OBDA) setting and investigate reasoning with inconsistent existential rules knowledge bases. We use the notion of inconsistency measures on sets of facts to rank and filter repairs. We propose a generic framework to answer queries by using the best repairs and study productivity and properties of such a framework.

Consumer perception data and scientific arguments about food packaging functionalities for fresh strawberries

This data article contains data characterizing consumer perception and scientific arguments about food packaging functionalities for fresh strawberries. These data are associated with the article “Choice of environment-friendly food packagings through argumentation systems and preferences” (see Yun et al., 2018). These data are stored in a public repository structured by an ontology. These data could be retrieved through the @Web tool, user-friendly interface to capitalize and query data (Buche et al., 2013; Guillard et al., 2017). The @Web tool is accessible online at http://pfl.grignon.inra.fr/atWeb/.

Graph Theoretical Properties of Logic Based Argumentation Frameworks: Proofs and General Results

Argumentation frameworks instantiated from logical language allow for argument generation over real knowledge. We present some graph theoretical properties of argumentation graphs obtained from an inconsistent knowledge base expressed using existential rules.
