Ontology modeling of domain knowledge in semantic learning Web

A methodology of ontology modeling on educational domain based on knowledge engineering was proposed to solve the problem of difficulty to construct domain knowledge ontology for multi-subjects.A complete ontology constructional model was built by defining domain knowledge scope,extracting concepts from domain knowledge,defining taxonomy and constructing relationship model based on concepts aggregation.The process to build domain ontology was simplified and domain experts were enabled to develop course ontology autonomously.A use case of ontology modeling for unified modeling language(UML) course was introduced and discussed,and the feasibility of the methodology was evaluated.
