摘要

在典型的技术先进地区,可以获得支持备灾和救灾决策及行动所急需的数据和信息,但这些数据和信息可能不仅存在于政府为灾害管理目的而建立的信息源中,也存在于其他政府机构、企业、机构、社交媒体等拥有的信息源中。使这些数据和资料容易被各种时间紧迫的备灾和救灾应用程序发现、获得和使用,应该是灾害管理信息系统的一个主要目标。本文提出了一个分布式框架,称为虚拟存储库,它利用链接的开放数据和相关技术来实现这一目标。应用程序可以使用构建在框架上的虚拟存储库(VR)来补充它所提供的信息源。除了设计和实现概念验证的VR原型外,本文还介绍了两个应用程序,游客自动灾害警报系统(ADAST)和灾害移动助手(MAD),作为案例研究,以展示VR的可行性和有效性。

Virtual disaster management information repository and applications based on linked open data
In a typical technologically advanced region, data and information critically needed to support disaster preparedness and response decisions and operations are available but may reside not only in sources built by the government for disaster management purposes, but also in information sources owned by other government agencies, businesses, institutions, social media, etc. Making such data and information easily discoverable, available and useable by diverse time-critical disaster preparedness and response applications should be a primary objective of disaster management information systems. This paper presents a distributed framework, called virtual repository, that leverages linked open data and related technologies to achieve this objective. Applications may use a virtual repository (VR) built on the framework to supplement information sources served by it. In addition to the design and implementation of a proof-of-concept VR prototype, the paper also presents two applications, Automatic Disaster Alert System for Tourists (ADAST) and Mobile Assistant for Disasters (MAD), as case studies to demonstrate the feasibility and effectiveness of VR.
