Abstract:

Aiming at the problems of ontology model used in emergency domain like unclear ontology classification and ineffective reuse, this paper proposes an emergency case ontology modeling and reuse method for urban disaster scenario. According to knowledge type and application purpose, the emergency case ontology is categorized, which achieves the independent representation of declarative knowledge and procedural knowledge of emergency case, and effective case retrieve, reuse and revise under objective constraints. The proposed method not only improves the rationality of established emergency response plan, but also simplifies the fussy processes of ontology-based reasoning. Finally, an example is given to prove the feasibility and validity of the proposed method in typhoon disaster for Z city power grid.

Key words: urban disaster scenario, emergency case, case-based reasoning, ontology modeling, ontology reuse
