为应急决策者提供快速而准确的决策知识和决策支持一直是应急领域的研究热点。本文首先构建了一个突发事件的基于框架的知识模型,可用于表示各类突发事件的知识。进而提出一种针对应急领域文本的基于知识模型的事实获取方法,主要包括文本预处理、事实的获取、事实的检验3个部分。最后通过实验验证了该方法的有效性,并取得了良好的效果。该模型为事实间的关系模式获取提供了基础,最终可为应急决策提供知识支持。
Providing emergency decision-makers with fast and accurate decision-making knowledge and decision support has always been a hot research topic in emergency field. This paper first builds a framework of knowledge-based knowledge of emergencies, which can be used to represent all kinds of emergencies. Then a new method based on knowledge model for emergency field text retrieval is proposed, which mainly includes three parts: preprocessing of text, obtaining of fact and testing of fact. Finally, the effectiveness of the method is verified by experiments and achieved good results. The model provides the basis for the acquisition of the relationship between the facts and finally provides the knowledge support for emergency decision-making.
