基于概念格的应急知识挖掘模型研究
发布时间：2018-08-12 20:02
【摘要】：本文提出一个面向增值的应急知识挖掘模型。以形式概念分析和概念格理论为基础,建立应急知识形式背景和应急知识概念格,通过格上作业,发现应急知识定域隐含的知识关系,达到应急知识增维的目的。实证结果表明,该模型具有良好的应急知识挖掘表现,所获得的高维应急知识能在一定程度上给下次同类型突发事件的应对提供启迪。
[Abstract]:In this paper, a value-added-oriented model of emergency knowledge mining is proposed. Based on formal concept analysis and concept lattice theory, the formal background of emergency knowledge and the concept lattice of emergency knowledge are established. The implicit knowledge relationships in the domain of emergency knowledge are found through the work on the lattice, and the purpose of increasing the dimension of emergency knowledge is achieved. The empirical results show that the model has a good performance of emergency knowledge mining, and the high dimensional emergency knowledge can provide some enlightenment for the next similar emergency response to some extent.
