The lockdown orders established in multiple countries in response to the Covid-19 pandemic 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.
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.
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.

多个国家为应对新冠疫情而实施的封锁令,可以说是近年来社会所经历的最广泛、最深刻的冲击之一。通过社交媒体的视角研究其影响,为理解人类活动模式对大规模外部冲击的敏感性和恢复力提供了前所未有的机会。首先,我们从在线时长、平台上分享的主题和情绪以及内容消费节奏等方面,调查这场剧变在网络活动中所引发的变化。其次,我们考察某些平台特征的恢复力,比如情绪表达的日常节奏。
关于法国网络空间的两个独立数据集:近10万条YouTube视频的细粒度时间记录,以及2020年2月17日至4月14日期间的800万条推文集合。
在两个数据集中,我们都观察到昼夜节律的重塑,封锁期间夜间活动有所增加。对封锁期间发布的视频和推文的分析表明,情感内容总体减少,主题从工作和金钱等转向死亡和安全等。然而,情绪的日常模式大多保持不变,这表明情绪周期对外源冲击具有恢复力。
