Study On Semantic Model Of Digital Emergency Plan Under The Scenarios-Cope Mode

A series of emergency like Wen Chuan earthquake, the southern snowstorm, motor car rear end collision have brought a serious threat to the safety of people's lives and properties, which gradually enhance the degree of our attention to the emergency. Constructing the rapid and effective emergency response mechanism is important guarantee to reduce the degree of emergency disaster to the utmost extent. Emergency plan as emergency an important basis for decision-making, its digital semantic model representation is the focus of research in academic circles for a long time, but knowledge playing an important role need to face certain application needs, and how to excavate and represent emergency domain knowledge needs, make emergency knowledge have certain application scenarios, and then realize decision-making model of providing emergency measures according to the application scenarios, becomes new research subject to handle with emergency effectively.This work is supported by National Nature Science Foundation of China(No.70871061). According to the main problems in the research of emergency plan digital representation model and knowledge push, scenarios application is introduced into emergency field, and the digital plan semantic model under the mode of"scenarios-cope"is constructed using ontology development and integration method. The specific main research contents include four parts as follows:1) The mode of'scenarios-cope'in emergency field is designed. On the basis of analysis on the existing problems of emergency knowledge management, the necessity and importance of constructing the model is elaborated, and according to the application of the model, and the connotation of the mode in emergency field is put forward, and on foundation of the analysis on knowledge construction in the mode, the mode of'scenarios-cope'in emergency field is designed and present.2) The emergency situation system and ontology representation model is constructed. Scene information which is needed for decision-maker in emergency field is extracted and summarized after analyzing actual emergency case, corresponding plan and related emergency event information. Then each of the factors in emergency situation system is modeled using the ontology relevant methods. 3) The representation model of emergency plan is constructed. On the basis of segmenting existing emergency plans, the core terms of emergency plan are extracted and classified. Combined with related concepts of ontology five meta-words and related theorems of OWL ontology, mining the mapping relationship between them, and on the basis of constructing ontology fundamental model, the ontology model of emergency plan is built.4) The scenario ontology and plan ontology are integrated into a new ontology model. By analyzing semantic relationship between emergency situation factors and emergency plan concepts, two ontology model mapping relationship is constructed. Then digital plan semantic model under the mode of'scenarios-cope'is realized using the ontology mapping method, and the model verified through an example.
