摘要
智慧城市领域的城市(管理)部件和事件信息包含概念、属性、关联关系等关键信息,这些信息之间相互关联。然而,当前城市部件和事件数据海量激增、关联性差等问题严重影响了应急响应、关联分析的速度。本文针对此问题提出了城市部件和事件本体模型,在此基础上从应急响应的角度设计了体现部件和事件关联关系的城市事件领域本体模型,最后映射为UML图并通过多元组逻辑描述。本文提出的模型可支持应急管理案例中的部件和事件关联分析和计算。
Urban managed components and event information in the field of smart cities contain key information such as concepts, attributes, and correlations, which are interrelated. However, the massive surge of urban components and event data and poor correlation seriously affect the speed of emergency response and correlation analysis. In view of this problem, this paper proposes the ontology model of urban components and events. On this basis, we design the ontology model of urban events that reflects the correlation between components and events from the perspective of emergency response. Finally, the model is mapped to a graph and formalized by multivariate groups. The proposed model can support component and event correlation analysis and calculation in emergency management cases.
