针对煤矿突发事件的特点,对一起瓦斯实例对案例的原始文本信息进行了规范化与知识化,基于数据库技术构建了案例库,提出了基于模板检索与最近邻法相结合的案例检索策略,并作了新的改善,最后提出了基于粗糙集理论的案例库优化方法.将案例推理应用于煤矿突发事件的预测决策中,具有一定的实际意义.
According to the characteristics of coal mine emergency, a case of gas data was normalized and knowledge-based on a case of gas. A case base was constructed based on database technology and a case retrieval strategy based on template retrieval and nearest neighbor method was proposed. Finally, a case-based optimization method based on rough set theory is put forward.It is of practical significance to apply case-based reasoning to the prediction of coal mine emergencies.
