在过去的十年里，政治事件数据集的发展出现了复兴。这至少是由于三组因素造成的。首先，技术变革降低了制作事件数据的成本，包括在网上提供信息，开发自动编码的专门系统，以及开发机器辅助系统，降低人工编码的成本。第二，事件数据已经变得比原来的国家为中心的数据集，如WEIS和COPDAB，更加重视次国家和非国家行为者，并在一些数据集，地理空间信息的纳入更加详细。最后，还有一些重大的机构投资，例如支持乌普萨拉和PRIO的一些数据集，DARPA ICEWS亚洲和全球数据集，以及美国政府的各种政治暴力数据集。本文将首先回顾主要的新贡献，重点是在这个特殊的问题，讨论现有数据中的一些开放性问题，最后讨论未来发展的前景，包括开源自然语言处理工具的增强使用，标准化的编码分类，以及近实时编码系统的前景。
The past decade has seen a renaissance in the development of political event data sets. This has been due to at least three sets of factors. First, there have been technological changes that have reduced the cost of producing event data, including the availability of information on the Web, the development of specialized systems for automated coding, and the development of machine-assisted systems that reduce the cost of human coding. Second, event data have become much more elaborate than the original state-centric data sets such as WEIS and COPDAB, with a far greater emphasis on substate and nonstate actors, and in some data sets, the incorporation of geospatial information. Finally, there have been major institutional investments, such as support for a number of Uppsala and PRIO data sets, the DARPA ICEWS Asian and global data sets, and various political violence data sets from the US government. This article will first review the major new contributions, with a focus on those represented in this special issue, discuss some of the open problems in the existing data and finally discuss prospects for future development, including the enhanced use of open-source natural language processing tools, standardizing the coding taxonomies, and prospects for near-real-time coding systems.
