突发公共事件时有发生,如何应用历史突发公共事件,快速获取应对当前突发事件的解决思路,以应对突发的公共事件,是急需解决的关键问题.通过对突发公共事件实体层级体系的研究,将其公共属性进行描述和抽取,采用OWL语言对突发公共事件的本体进行了描述,并给出了突发公共事件的元事件的定义,讨论了元事件之间的相互关系.结合CBR的相关理念,提出了基于元事件的突发公共事件的推理机制,使得决策者依据元事件库可以快速地获得应急处置方案;最后实例验证和说明该模型具有良好的应用效果.%Public emergencies occur constantly. How to apply history public emergencies and obtain corresponding solutions rapidly is the key problem for coping with public emergencies. The level system of entity of public emergencies is researched, and the public attributes are described and extracted. OWL language is adopted to describe the ontology of public emergency, the definition of meta event is proposed, and the relationship among the meta events is discussed. Combining the related theory of CBR, the reasoning mechanism based on meta event is put forward, which will make decision-maker obtain the disposal schema rapidly according to meta event database. Finally, an example testified the feasibility.
