论文摘要
语境。在多个国家 /地区对COVID-19-Pandemics的响应中建立的锁定命令可以说是近年来社会经历的最广泛和最深切的冲击之一。研究他们的影响槽社交媒体的镜头为了解人类活动模式对大规模外源性冲击的易感性和韧性提供了前所未有的机会。首先，我们调查了这种动荡的变化在网上活动中所造成的变化，在平台上共享的主题和情感以及内容消费的节奏。其次，我们检查了某些平台特征的弹性，例如情绪表达的每日节奏。数据。关于法国网络空间的两个独立数据集：在2020年2月17日至4月14日之间，有近1万YouTube视频的细粒度时间记录和800万条推文。在两个数据集中，我们都会观察到昼夜节律的重塑，并在锁定过程中增加了夜间活动。对锁定期间发表的视频和推文的分析表明，情感内容的总体下降以及从工作和金钱等主题转变为死亡和安全等主题。但是，情绪的日常模式主要保持不变，从而表明情绪循环对外源性冲击有弹性。
Context. The lockdown orders established in multiple countries in response to the Covid-19 pandemics are arguably one of the most widespread and deepest shock experienced by societies in recent years. Studying their impact trough the lens of social media offers an unprecedented opportunity to understand the susceptibility and the resilience of human activity patterns to large-scale exogenous shocks. Firstly, we investigate the changes that this upheaval has caused in online activity in terms of time spent online, themes and emotion shared on the platforms, and rhythms of content consumption. Secondly, we examine the resilience of certain platform characteristics, such as the daily rhythms of emotion expression. Data. Two independent datasets about the French cyberspace: a fine-grained temporal record of almost 100 thousand YouTube videos and a collection of 8 million Tweets between February 17 and April 14, 2020. Findings. In both datasets we observe a reshaping of the circadian rhythms with an increase of night activity during the lockdown. The analysis of the videos and tweets published during lockdown shows a general decrease in emotional contents and a shift from themes like work and money to themes like death and safety. However, the daily patterns of emotions remain mostly unchanged, thereby suggesting that emotional cycles are resilient to exogenous shocks.
