Social media has become central to the public's response to terrorism. From the transmission of breaking news, to the offering of social support, to the dissemination of radical, hateful messages, people increasingly turn to social media to both share and gain understandings of terrorist events. This project utilizes the social media data to investigate the reactions of individuals located in Paris during the November 2015 attacks. It analyzes both their immediate social and emotional reactions to the attacks as well as longer-term changes in their communication behavior. The investigation focuses on three questions. First, in immediate response to the attacks, how, and how effectively, did improvised logistical communications, such as the use of the #PorteOuverte hashtag offering shelter to strangers, emerge in the chaotic and emotional context of the attack aftermath. Second, what effect did attention by individuals to different aspects of the attack, such as particular news stories, the role of different ethnic groups, or other salient aspects of social media discussion after the attacks influence their longer term attitudes toward the threat of terrorism. Third, how and to what extent did government authorities and professional news outlets sway this public attention both broadly and for specific social communities. This research outcome will both improve responses to specific terrorist attacks as well as enhance public understanding of the specific means through which terrorism wields social influence. The project advances the theoretical study of collective sensemaking, understood here as the emergent, communal attempt to cognitively understand, emotionally accept, and logistically respond to surprising, disruptive events. The project addresses collective sensemaking in a novel way by focusing on both temporal and subject based differences. Analysis will focus on both short-term and longer-term communication behavioral changes, such as changes in the expression of sentiment or of reference to specific URLs. Methodological issues such as selection bias and the measurement of different sensemaking behaviors will be addressed by leveraging text mining, network science methods and techniques, and communication theories of social media. In so doing, the project will greatly improved understanding of both the immediate and longer-term behavioral responses of citizens to a terrorist attack.

社交媒体已成为公众对恐怖主义反应的核心。 从突发新闻的传播到提供社会支持，再到激进，仇恨信息的传播，人们越来越多地转向社交媒体，既分享并获得对恐怖事件的理解。该项目利用社交媒体数据在2015年11月的袭击中调查位于巴黎的个人的反应。它分析了他们对攻击的直接社会和情感反应以及其沟通行为的长期变化。调查侧重于三个问题。 首先，在对攻击的直接响应中，即兴以及如何有效地进行了即兴后勤沟通，例如使用#porteouverte主题标签向陌生人提供庇护所，在攻击后的混乱和情感环境中出现了庇护所。 其次，个人对攻击的不同方面的关注使什么影响，例如特定的新闻故事，不同种族群体的作用或攻击后社交媒体讨论的其他显着方面影响了他们对恐怖主义威胁的长期态度。 第三，政府当局和专业新闻媒体如何以及在多大程度上遍布广泛的社会社区和特定社会社区的关注。这项研究结果将改善对特定恐怖袭击的反应，并增强公众对恐怖主义产生社会影响力的特定手段的理解。该项目推进了集体感官的理论研究，在这里被理解为现实的，共同的共同尝试，以认知理解，在情感上接受和对逻辑上回应令人惊讶的，破坏性的事件。 该项目通过专注于时间和基于主题的差异来以一种新颖的方式解决集体感官。 分析将侧重于短期和长期沟通行为的变化，例如情感表达或参考特定URL的变化。 通过利用文本挖掘，网络科学方法和技术以及社交媒体的交流理论来解决方法论问题，例如选择偏见和测量不同的感官行为。这样一来，该项目将大大改善对公民对恐怖袭击的直接和长期行为反应的理解。
