ArgDF: Arguments on the Semantic Web

This dissertation explores the incorporation of the Semantic Web technology with one of the latest argument representation formats. First I introduce an extension of the Argument Interchange Format (AIF) ontology; then I put for-ward AIF-RDF, which is the extended ontology represented in the Resource Description Framework Schema (RDFS) semantic language. Finally, based on the theoretical and ontology foundations described in the thesis, I present the implementation of ArgDF: a Semantic Web-based system built to represent and visualize arguments. ArgDF comprises a set of tools such as the integration of a variety of argumentation schemes with the possibility of adding new schemes from the user interface. Another feature is to attack and support existing ex-pressions in ArgDF, or to use existing statements in new arguments, leading to the possibility of building a set of interlinked arguments networks. ArgDF is the outcome of the fusion of the Semantic Web with the argument represen-tation format theory, resulting in the emergence of a rich application tool fo
