Object-Oriented Method of Constructing Electric Power System Domain Ontology Based on Protégé

This paper presents a method for domain ontology of constructing power system based on Protégé . This paper describes how to package Interoperability Portlet into semantic Portlet, then create semantic data association between ontology-based semantic Portlet and using semantic inference rules to realize Portlet interoperability. The main task of this paper is to construct and deploy (service release) ontology, find out the concept of the power of public information model CIM about our project, create an XML format file with tools such as Protégé . This paper will elaborate on the use of object-oriented constructed method for constructing the ontology. The construction of the ontology tree provides the foundation of Web services’ semantic annotation.
