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.

该项目的目标是开发各种手段，以提高信息质量和在应急反应中的使用，增加灾害期间使用来自非专业参与者群体的信息和微博数据的价值。尽管有证据表明，这些信息对遭受灾害的人和寻求有关灾害信息的人具有很强的价值，但在检测社交媒体信息流中信息的相关性和真实性方面，却几乎没有做出任何努力。 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传递给参与应急响应的组织。 因此，该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，从而更好地支持那些需要他们的人，并挽救更多的生命。这项研究将有助于应急和灾害研究领域，通过绘制应急响应期间的关键决策，在这些决策点期间，信息需要、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查的标准。它还将调查相关和可验证的标识符（或特征），提供权重，将其纳入分析框架，并将分析结果用作可扩展计算模型的输入。这项工作将设计算法，可以估计的相关性和准确性的消息在一个高容量的流文本组成的短消息。鉴于团队的不同背景，它将有助于社会技术系统理论的使用和发展，以分析技术和社会系统的整合。模型的产出将符合作出回应的组织的组织需要。
