论文摘要
物联网，众包，社交媒体，公共当局和其他来源产生越来越大的数据集。 Big and Open数据为紧急管理提供了许多好处，但也带来了新的挑战。本章将回顾大数据及其特征的来源。然后，我们讨论大数据在紧急管理方面的潜在好处，以及其提出的技术和社会挑战。在更详细地展示Spark Big-Data引擎之前，我们一般审查了用于大数据存储和处理的中央技术。最后，我们回顾了大数据构成的道德和社会威胁。
The Internet of Things, crowdsourcing, social media, public authorities, and other sources generate bigger and bigger data sets. Big and open data offers many benefits for emergency management, but also pose new challenges. This chapter will review the sources of big data and their characteristics. We then discuss potential benefits of big data for emergency management along with the technological and societal challenges it poses. We review central technologies for big-data storage and processing in general, before presenting the Spark big-data engine in more detail. Finally, we review ethical and societal threats that big data pose.
