Study on IETM domain ontology representation and reasoning based on semantic Web

To make IETM (interactive electronic technical manual) contents understandable to machine and suitable for inference, ontology needs to be established, and the IETM contents should be annotated with metadata which are defined as terminology in ontology. The relation between ontology and IETM domain ontology is explained; the overview of ontology languages for the semantic Web is introduced; based on trade-off between expressivity of knowledge and complexity of reasoning problems, OWLLite is selected as ontology language; then IDORRSW (IETM domain ontology representation and reasoning for the semantic Web) is proposed. From these discussions, the basic situations of domain ontology representation, reasoning and integration for the semantic Web are clarified, so the basic knowledge of developing ontology for the semantic Web is provided.
