In view of the characteristics of information in emergency management operation and the requirements of information share in urban rail transit, the ontology theory has been introduced in standardization of emergency information. Authors established a model of ontology description through dividing emergency process into several stages and related objects to construct an identical frame of expression for emergency information sharing, and set up rules to construct identification and mapping for information ontology and logic of operation. Semantic matching and relevancy expansion were applied to optimize the treatment scheme suitable for the layout of the scene, to realize decision-making based on information integration.%针对城市轨道交通应急管理业务的信息特征及信息共享需求,将本体论引入应急信息标准化;根据应急处置流程划分阶段及其业务对象,建立本体知识表达模型,构建共享所需的规范化框架,设立规则对信息本体、业务逻辑进行辨识和映射.应用语义匹配、关联扩展策略,制订和修正处置方案来用于现场布局,以实现信息集成对应急决策的支撑.
