摘　　要：燃气事故发生时,应急处置人员基于文本资料查询应急处置方案难以满足处置科学性与快速性的需求。为此,提出了一种融合知识图谱和案例推理的燃气应急辅助决策方法。将已有燃气事故案例文本资料以知识图谱的形式存储与表示,利用案例推理的属性相似度与关系相似度加权计算方法,根据事故目标案例与源案例的综合相似度,检索出最佳相似源案例作为现场处置人员应急处置决策的重要参考,并将新的案例与处置措施存储于燃气应急处置知识图谱库中,实现处置措施的知识更新。通过案例相似度权重分配、属性权重分配、属性相似度方法选取,以及案例验证等,验证了本文方法的合理性与有效性。A gas emergency decision-making method that inte-grates knowledge graph and case-based reasoning is proposed to address the difficulty of emergency response personnel searching for emergency response plans based on text data to meet the needs of scientific and rapid response in the current occurrence of gas accidents.Store and represent existing text data of gas acci-dent cases in the form of a knowledge graph,propose a weighted calculation method for attribute similarity and relationship similar-ity in case reasoning,and based on the comprehensive similarity between the accident target case and the source case,retrieve the best similar source case as an important reference for emergency response decisions of on-site disposal personnel.Store new cases and disposal measures in the gas emergency response knowledge graph database,updated knowledge on implementation of dis-posal measures.The rationality and effectiveness of our method were verified through experiments such as case similarity weight allocation,attribute weight allocation,selection of attribute simi-larity methods,and case validation.
