An ontology-based e-learning system for network security

Effective information services could be provided for users by investing meta-data in information sources and making software agents understand at. In thzs paper, we make better use of a collection (ontology) of meta-data in the Semantic Web technology for the design of an e-learning system that enables to provide learners with a more effective education support. The learning domain is cryptography in network security. We define vanous concepts in the cryptographic domain and the relations among them as the ontology, and propose a way of utilizing ct an the learning process. The strength of our ontology-based e-learnzng system as demonstrated through application examples ojtheprototype system that we have been developing.
