Desarrollo de una aplicación basada en la web semántica para consultar cursos virtuales usando el framework Jena.

Abstract

The objetive was to develo pan application in semantic web that allows to consult formalized Information of virtual courses using the Jena Framework for the teachers of the School od Engineering in Systems (EIS) of the Escuela Superior Politecnica de Chimborazo. The methodologies used to design the application were Noy & McGuinness and Scrum, the first to define the ontology representing a way to carry out reengineering or computer processes, that is, it allows to renew these processes according to the needs or requirements stipulated witin the design. Being a flexible methodological mechanism on the domain or other applications around objects and relations of the same. The second; for the fulfillment of the phases of planning and development of the project, working in a interactive way between the user nd the client, in order to anticípate unnecessary expenses of the maintenance of the system after its commissioning or delivery to the user, at the same time guarantees the development of quality software that meets the user´s accessibility requirements. The technologies used were: Protects for ontological using, OWL language. IDE Netbeans and JENA framework for the development of SPARQL application that allows to link the application with the ontology. The results obtained for the access and processing waere performed through the design of the questionnaire, in addition was evaluated obtaining 74% with criteria of excellent performance. In conlusion, the application developed is optimal and functional in compliance with the stated objectives; therefore its use is recommended because it allows to obtain formal Information of the virtual courses.
