Ontological Support for Web Courseware Authoring System Based on SCORM

In the paper, we use ontology technology to construct a web courseware authoring system and realize the semantic interoperation in heterogeneous e-learning systems. We set up a domain ontology model which is core component of the system, and can be related with the knowledge concept in domain ontology base with learning resources in the learning resources repository. Then we use the SCORM simple sequencing model to set up the clusters of learning activity to form the agile and adaptive course structure, and map the learning activity clusters encapsulated by SCORM onto OWL language. Based on the domain ontology, a semantic conflict elimination model is put forward, which is the foundation to resolve semantic confliction in authoring courseware cooperatively. Finally we prove that by using the technology of semantic web and all kinds of learning recourses standards we can resolve the interoperation of heterogeneous e-learning systems.
