SIOC-Argumentation Extended Vocabulary

To provide a further semantic machine readable representation of our argumentative discussions, we decide to not introduce yet another argumentation vocabulary, but we reuse the SIOC Argumentation vocabulary [RDF] which is focused on the fine-grained representation of discussions and argumentations in online communities.

We extend the SIOC Argumentation vocabulary [RDF] with two new properties sioc_arg:challengesArg and sioc_arg:supportsArg whose range and domain are sioc_arg:Argument. These properties represent challenges and supports from arguments to arguments, as required in abstract bipolar argumentation theory.


The XML/RDF format adopted in NoDE relies on the SIOC-Argumentation extended vocabulary. Each argument is a sioc_arg:Argument, and the two relations of support and attack are respectively characterized by the properties sioc_arg:supportsArg and sioc_arg:challengesArg (respectively mapped on the entailment and non entailment relations).

An example from the Twelve Angry Men XML/RDF dataset is as follows:

<> rdf:type sioc_arg:Argument ; sioc:content "Ever since he was five years old his father beat him up regularly. He used his fists." ; sioc_arg:challengesArg <> . <> rdf:type sioc_arg:Argument ; sioc:content "Look at the kid’s record. At fifteen he was in reform school. He stole a car. He was picked up for knife-fighting. I think they said he stabbed somebody in the arm. This is a very fine boy." .
