Graphical Representation of OWL 2 Ontologies through Graphol

We present Graphol, a novel language for the diagrammatic representation of ontologies. Graphol is designed to offer a completely visual representation to the users, thus helping the understanding of people not skilled in logic. At the same time, it provides designers with simple mechanisms for ontology editing, which free them from having to write down complex textual syntax. Through Graphol we can specify SROIQ(D) ontologies, thus our language essentially captures the OWL 2 standard. In this respect, we developed a basic software tool to translate Graphol ontologies realized with the yEd graph editor into OWL 2 functional syntax specifications
