An Ontology Mapping Algorithm to Share Learning Resources

In order to deal with the need of sharing learning objects within and across learning object repositories most of the work argue for the use of ontologies as a means for providing a shared understanding of common domains. But with the proliferation of much different ontology even for the same domain, it becomes necessary to provide a mapping process to perform interoperability. Two key issues must be addressed: the first one is to provide help to users describing and searching resources by organizing the knowledge covered by the learning resources and the second one is to define educational systems interoperability mechanisms to create a virtual learning space. Although many efforts in ontology mapping have already been carried out, few of them use resources properties to generate relations between local concepts and discover mapping dynamically
