基于知识元的应急管理案例情景化表示及存储模式研究

应急管理案例蕴含了大量的应急管理知识,如何有效利用这些知识,提高应急管理案例的应用价值,是当前应急管理研究的难点.通过引入共性知识元模型,以知识元的形式抽取领域内突发事件应急管理共性知识,形成共性可扩展的应急知识元体系.同时对应急管理案例进行情景的划分,在此基础上对应急管理案例情景序列的知识结构进行分析,结合应急知识元体系提出应急管理案例的情景化表示及存储模式,使应急过程各阶段的信息相分离,形成基于知识元的应急管理案例情景库,更加满足"情景-应对"模式中案例推理的需要.

Research on scenario representation and storage model of the emergency cases based on knowledge element

Emergency management cases contain quantity of knowledge about emergency management, how to use this knowledge to improve the application value of emergency management cases effectively is the difficulty of present emergency management research. By the introduction of a common knowledge element model, the article extracts common knowledge of emergency management in the form of the knowledge elements, constructing the common and extensible emergency knowledge system, and divides the emergency management cases into scenarios, on this basis analyzing the knowledge structural of scenario sequence about emergency management cases, and then proposes a mode of scenario representation and storage to re-represents and re-stores emergency management cases combined with the emergency knowledge system. The scenario mode could split the various stages information of the emergency procedure, and form the emergency management cases scenario database based on knowledge element. These would better meet the needs of case-based reasoning in "scenario-response".
