面对短时间内在多个国家发生的起义和革命(2011年阿拉伯之春),快速网络评估的需求是迫切的。在这篇文章中,我们提出了一种快速的网络评估方法,它使用大量的预先索引的新闻数据,以提供最新的概述和方向,在新兴和正在发生的事件。我们描述了准备数据和创建动态元网络的全自动化过程。我们还描述了网络分析措施,我们正在使用这些网络中的重要主题,人员,组织和位置。借助我们的快速网络建模和分析方法,可在数小时内提供第一批结果。在本文的探索性研究中,我们使用了来自600多个英语书面新闻来源的108,000多篇文章,在18个月的时间内讨论埃及,利比亚和苏丹,以展示我们方法的应用场景。特别是,我们正在研究其他国家及其政治家在重大事件发生期间的参与情况。
In the face of uprisings and revolutions happening in several countries within short period of time (Arab Spring 2011), the need for fast network assessments is compelling. In this article we present a rapid network assessment approach which uses a vast amount of pre-indexed news data to provide up-to-date overview and orientation in emerging and ongoing incidents. We describe the fully automated process of preparing the data and creating the dynamic meta-networks. We also describe the network analytical measures that we are using to identify important topics, persons, organizations, and locations in these networks. With our rapid network modeling and analysis approach first results can be provided within hours. In the explorative study of this article we use 108,000+ articles from 600+ English written news sources discussing Egypt, Libya, and Sudan within a time period of 18 months to show an application scenario of our approach. In particular we are looking at the involvement of other countries and their politicians during time periods of major incidents.
