Furthermore, the emergency plan ontology model is realized using protégé 4; By means of building the mapping relationship between meta-words of ontology and parts of OWL ontology which is verified by experiment, representation formalism of emergency plan is also realized. The general fundamental model of ontology is summarized in this experiment process and these works would provide help in knowledge representation based on ontology.]]>Mendonca, D., G.E.G.
