OntoDiccionario is a software application capable of displaying the conceptual and terminological information implemented in a RDF/OWL ontology (created by means of the program TopBraid Composer); it allows the users to search for terms and to navigate through concepts by means of hyperlinks. The application is based on the idea of taking the ontology code and parsing its content, in such a way that all classes, relations, properties and labels are captured; these data are then represented on a simple user interface, which includes a list of concepts, search engine, and a display window that shows the data for each concept.
