论文摘要
由于Covid-19的爆发，用户越来越多地转向在线服务。还观察到了社交媒体使用的增加，导致人们怀疑这也增加了网络欺凌。在这项最初的工作中，我们探讨了由于大流行和高度社交媒体使用而增加网络欺凌事件的可能性。为了评估这一趋势，我们在2020年1月1日至2020年6月7日之间收集了454,046个与网络欺凌有关的公共推文。我们总结了包含多个关键字的推文中的日常计数。我们的分析表明，大多数这些关键字最多存在一个统计学意义的更改点，这些关键字主要位于3月底。几乎所有这些更改点的时间分配都可以归因于Covid-19，这证实了我们通过通过Twitter分析讨论的分析来证实网络欺凌的最初假设。
Due to the outbreak of COVID-19, users are increasingly turning to online services. An increase in social media usage has also been observed, leading to the suspicion that this has also raised cyberbullying. In this initial work, we explore the possibility of an increase in cyberbullying incidents due to the pandemic and high social media usage. To evaluate this trend, we collected 454,046 cyberbullying-related public tweets posted between January 1st, 2020 -- June 7th, 2020. We summarize the tweets containing multiple keywords into their daily counts. Our analysis showed the existence of at most one statistically significant changepoint for most of these keywords, which were primarily located around the end of March. Almost all these changepoint time-locations can be attributed to COVID-19, which substantiates our initial hypothesis of an increase in cyberbullying through analysis of discussions over Twitter.
