非煤矿山安全专家系统知识库的建立

Establishment of Knowledge Base of Non-coal Mine Safety Expert System

非煤矿山安全生产系统要从传统的安全信息管理转变为智能化信息处理,需要集成大量安全知识。运用基于粗糙集理论改进ID3算法的决策树获取安全知识,采用产生式表示法表示非煤矿山的描述性及过程性安全知识。然后利用Access技术,设计互相关联二维表存储安全知识,构建非煤矿山的安全知识库。

To upgrade Non-coal mine safety system from traditional safety information management to the intellectual- ized decision of safety information,it needs to integrate massive safety knowledge. The rough set theory was adopted to im- prove a decision tree of ID3 （ Interactive Dichotomic Version 3 ） algorithm to obtain the safety knowledge of non-coal underground mine. And the descriptive safety knowledge and the procedural safety knowledge can be expressed by using producing representation. The interrelated two-dimensional list is designed to store the safety knowledge and model the safety knowl- edge base of non-coal mine by using Access technique.
