Expressing argumentative discussions in social media sites

Among the activities that people participate in on the Social Web are argumentative discussions and decision making. This paper analyzes a series of use-cases (from the perspective of social media sites) that share the presence of such argumentative discussions and where the structure of online discussions can be represented in SIOC. Our goal is to externalize implicit argumentation structures hidden in the usergenerated content. For capturing it and making it explicit, we propose a SIOC Argumentation ontology module as a formal representation.
