Abstract

Emergency preplans describe domain knowledge for emergency handling, but most of them are formed in static text or electronic document which is difficult for emergency decision-makers to achieve accurately and quickly. For solving the problems above, we put forward an emergency preplan knowledge representation framework. First, we analyzed emergency preplan textual knowledge and achieved three kinds of knowledge in different levels. Then, an emergency preplan ontology was built and the way to represent emergency preplan knowledge was proposed. Finally, an emergency preplan semantic retrieval system was implemented with the help of ontology reasoning mechanism.
基于本体的应急预案知识表示与语义检索系统
应急预案描述了应急处理的领域知识,但大多以静态文本或电子文档的形式形成,难以准确、快速地实现应急决策。针对上述问题,提出了一个应急预案知识表示框架。首先,我们对应急预案文本知识进行了分析,得到了三种不同层次的知识。然后,建立了应急预案本体,提出了应急预案知识的表示方法。最后,利用本体推理机制实现了应急预案语义检索系统。
