铁路调度应急预案知识图谱构建

Construction of knowledge graph of railway dispatching emergency plan

为解决铁路调度应急预案信息整合困难、综合管理能力不足的问题,采用知识图谱概念和方法,对铁路调度应急预案相关信息资源进行全面梳理和系统分析,采用自顶向下与自底向上相结合的方法,完成铁路调度应急预案知识图谱的构建;提出铁路调度应急预案主要实体概念及其属性与关系的定义,研究数据抽取、数据融合及知识存储的方法,实铁路调度应急预案数据的规范、有序存储。以雾天行车场景为例,开展应用探索。应用表明,知识图谱为整合多源异构的铁路调度应急预案相关信息资源提供了有力工具,使应急预案相关信息资源的使用更加便利化,更好地支持应急指挥快速决策,支持应急处置工作从容有序开展。

To address the difficulties in information integration and insufficient of comprehensive management ability of railway dispatching emergency plan,The concept and approach of knowledge graph is employed to sort and analyze relevant information resources of railway dispatching emergency plan.Using a combination of top-down and bottom-up method,the knowledge graph of railway dispatching emergency plan is constructed,in which the core elements of railway dispatching emergency plan are indentified and their properties and associations are defined.Besides,the methods of data extraction,data fusion and knowledge storage are studied to realize standardized and orderly organization and storage of railway dispatching emergency plan data.Taking train operation in foggy weather as a study case,the application of the knowledge graph of railway dispatching emergency plan is explored.The application shows that knowledge graph can be a powerful tool for integrating multi-source and heterogeneous related information resources of railway dispatching emergency plan and facilitate the utilization of those resources and better support rapid decision-making in emergency command and and support emergency response rolling out in a calm and orderly manner.
