Study and application of emergency case Ontology model

Emergency case is always considered as the important support in emergency response system.The massive emergency case information from network is exploded in exponential trend.However,because of the heterogeneous quality of opening Web,it is difficult in understanding and using these cases.An Emergency Case Ontology Model(ECOM) was proposed as the knowledge representation of emergency case,which was divided into upper Ontology and application Ontology.The upper Ontology named eABC was expanded based on the ABC Ontology,and the application Ontology,which was represented as a 5-array of concepts,relations,functions,axioms and instances,was composed of emergency case subject,emergency case object,and emergency event developmental process and so on.In ECOM,Web resource location was considered to assess the reliability of the cases information.Finally,the validity of ECOM was testified by an example of Wenchuan earthquake description.
