Study on Construction of Emergency Plan Ontology Model

On the basis of experiment of word segmentation and extraction for emergency plan, combining with meta-words of ontology, this paper extracts and classifies the core terms of emergency plan and then the concept classes, related properties and instances are established. Furthermore, the emergency plan ontology model is realized using protg 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.
