%X 基于案例推理的方法系统构建了地铁运营安全事故案例库框架,提出将前兆信息作为案例的索引,实现案例推理.运用框架表示法对地铁运营安全事故案例中的信息进行结构化的描述.在利用前兆信息进行案例检索的过程中,运用基于语义信息的概念树相似度计算方法,对人员前兆信息的部分概念之间的相似度进行计算.在此基础上,计算全局相似度,实现案例之间的相似度比较.最后运用Protégé软件及MyCBR插件,以4个典型的地铁事故为例,构建了地铁运营安全事故的案例库,实现相似案例的自动输出,为地铁运营安全风险管理者提供智能决策.<br>A frame of subway accident case database is systematically constructed based on case-based reasoning(CBR). In order to achieve the reasoning, the precursor information is used as index. The information in each subway accident case is structurally described by means of frame representation. During the process of case retrieval with precursor, the conceptual similarity computation method based on semantic information is used to compute the local similarity between parts of precursors from workers. On this basis, the global similarity is computed to achieve the comparison between the cases. Finally, taking four typical accidents as examples,the subway accident case database is constructed by using the Protégé software and MyCBR add-in, and automatical output of similar cases is realized,which provides an intelligent decision for the subway operation safety risk manager
