针对突发事件数据资源多源、异构、海量等特点,结合突发事件信息平台建设,提出了面向数据服务的应急数据标准化方法。利用此方法,分析了应急活动流程、数据需求和数据服务需求,结合突发事件数据资源组织模式,建立了基于实体、事件、任务的标准化对象。基于应急处置信息平台数据服务架构,建立了涵盖数据、服务、管理的数据标准要素,为实现数据资源的共享交换、抽取分发、异构聚合提供支持。 According to the characteristics of multi-source, heterogeneous and massive data resources of emergency, combined with the construction of emergency information platform, the emergency data standardization method for data service was proposed. By using this method, the emergency activities flow, data requirements and data service requirements are analyzed. Based on the organization model of emergency data resources, a standardized object based on entities, events and tasks is established. Based on the emergency service information platform data service architecture, a data standard element covering data, service and management was established, providing support for sharing data exchange, extraction and distribution, heterogeneous aggregation.
