• Resumen

  • This paper proposes an ontology mapping-based framewrowrk that allows searching for learning resources using multiple ontologies. The present applications of ontologies in e-learning use various ontologies (eg, domain, curriculum, context), but they do not give a solution on how to interoperate e-learning systems based on different ontologies. The proposed solution uses a mapping ontology that is a part of a recent Semantic Web initiative, the Simple Knowledge Organisation System. On top of that, we develop and implement two search algorithms. Finally, we evaluated the solution by developing a system that helps students search for relevant learning resource using a local context (ie, course curriculum) ontology. [ABSTRACT FROM AUTHOR]
