【摘要】:本文提出一個面向增值的應急知識挖掘模型。以形式概念分析和概念格理論為基礎,建立應急知識形式背景和應急知識概念格,通過格上作業(yè),發(fā)現(xiàn)應急知識定域隱含的知識關系,達到應急知識增維的目的。實證結(jié)果表明,該模型具有良好的應急知識挖掘表現(xiàn),所獲得的高維應急知識能在一定程度上給下次同類型突發(fā)事件的應對提供啟迪。
[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.
