In the crisis management literature information shared on social media during a crisis is relevant both to emergency agencies, when it establishes a more accurate situational awareness, and to citizens, when it enables a collective and coherent approach to the event (e.g. Stieglitz, Bunker, Mirbabaie & Ehnis, 2018, Journal of Contingencies and Crisis Management, 26(1), 4). Social media is, however, also considered as a place where “noise” and fake news can be dispensed (e.g., Alexander, 2014, Science and Engineering Ethics, 20(3), 717; Starbird, 2017, https://www.aaai.org/ocs/index.php/ICWSM/ICWSM17/paper/view/15603). In this paper, we analyse contributions on Wikipedia and Twitter during major crises in France through online ethnographies and semi‐structured interviews to investigate their roles in building and sharing information. Wikipedia has often been analysed as a collaborative tool but this approach has underestimated its use in reducing uncertainty in times of crisis. We demonstrate that despite their distinct pace and designs, Twitter and Wikipedia are used with seriousness by citizens in their dissemination of information. We also explain how social media change the landscape of means of communication for official institutions and citizens, and that they can be used in the same way. Finally, we stress the need for official institutions to integrate social media in their practices and interactions with citizens that they involve.

危机期间法国社交媒体上信息准确性的构建和传播：Twitter和Wikipedia的比较

在危机管理中，危机期间在社交媒体上共享的文献信息不仅与应急机构（建立更准确的态势感知）有关，也与公民（使Stieglitz，Bunker， Mirbabaie＆Ehnis，2018，突发事件与危机管理杂志，26（1），4）。但是，社交媒体也被认为是可以散布“噪音”和虚假新闻的地方（例如，亚历山大，2014年，《科学与工程伦理学》，20（3），717；《星鸟》，2017年，https：//www.aaai.org/ocs/index.php/ICWSM/ICWSM17/paper/view/15603）。在本文中，我们通过在线人种志和半结构化访谈来分析法国在重大危机期间对Wikipedia和Twitter的贡献，以调查它们在建立和共享信息中的作用。Wikipedia通常被视为一种协作工具，但是这种方法低估了其在减少危机时期不确定性方面的使用。我们证明，尽管Twitter和Wikipedia具有截然不同的步调和设计，但它们在公民传播信息方面仍被认真使用。我们还将说明社交媒体如何改变官方机构和公民的通讯方式，并以相同的方式使用它们。最后，
