CHS: Small: Collaborative Research: Automating Relevance and Trust Detection in Social Media Data for Emergency Response

这个项目的目标是发展提高信息质量和在应急反应中的使用的手段，增加灾害期间使用非专业参与者群体的消息传递和微博数据的价值。尽管这些证据对那些经历灾难的人和那些寻求灾难信息的人具有很强的价值，但在检测社交媒体流中信息的相关性和准确性方面却做得很少。数据验证问题是考虑使用社交媒体数据的应急组织面临的最大问题之一。本研究通过测量相关和可验证信息的方法直接解决了这一已知问题。这项研究的结果将直接提供给参与应急反应的组织。因此，这项研究有可能帮助应对紧急情况的组织利用大量公民产生的数据，从而提高应急响应的速度、质量和效率，从而更好地向需要的人提供支持，并挽救更多的生命。这项研究将对紧急情况和灾害研究领域作出贡献，绘制出应急反应期间作出的关键决策、这些决策点期间的信息需求、类型、形式和流动，最重要的是，评估每个决策点的数据质量和可核实的标准。它还将研究相关和可验证的标识符（或特征），提供权重，将这些权重合并到分析框架中，并将分析结果作为可扩展计算模型的输入。这项工作将设计算法，可以在由短消息组成的大量流文本中估计消息的相关性和准确性。鉴于团队的不同背景，它将有助于使用和发展社会技术系统理论来分析技术和社会系统的整合。模型的输出将与响应组织的组织需求相匹配。

The goal of this project is to develop means to improve information quality and use in emergency response, increasing the value of using messaging and microblogged data from crowds of non-professional participants during disasters. Despite the evidence of strong value to those experiencing the disaster and those seeking information concerning the disaster, there has been very little effort in detecting the relevance and veracity of messages in social media streams. The problem of data verification is one of the largest problems confronting emergency-response organizations contemplating using social media data. This research directly addresses this known problem by methods to measure relevant and verifiable information. The results of this research will have a direct pipeline to organizations involved in emergency response. Therefore the research has the potential to help organizations, which respond to emergencies, make use of large amounts of citizen-produced data, which in turn may improve the speed, quality, and efficiency of emergency response leading to better support to those who need them, and more lives saved.This research will contribute to the field of Emergency and Disaster Studies by mapping the key decisions made during an emergency response, the information needs, type, form and flow during those decision points, and most importantly, assessing data quality and verifiable standards for each. It will also investigate relevant and verifiable identifiers (or features), provide weights, incorporate these into an analytical framework, and use the results of the analysis as input to scalable computational models. The work will design algorithms that can estimate the relevance and veracity of messages in a high-volume streaming text comprised of short messages. Given the diverse backgrounds of the team, it will contribute to the use and development of socio-technical systems theory to analyze the integration of technical and social systems. The output of the models will match the organizational needs of responding organizations.
