论文摘要
随着小说的冠状病毒在全球范围内传播，互联网上越来越多地表达了公众的恐慌。我们在Twitter上研究了有关Covid-19的公众讨论。我们使用了从1月29日，2020年至2020年3月4日收集的1200万用户的6700万推文的数据集。我们根据用户的本国，社会身份和政治取向对用户进行分类。我们发现新闻媒体，政府官员和个人新闻记者发布了大多数有影响力的推文，而最有影响力的推文仍然是普通用户写的。提到“假新闻” URL和虚假信息故事情节的推文也更有可能由常规用户传播。与真正的新闻和普通推文不同，包含指向“假新闻”网站的URL的推文最有可能在源国家内转发，因此国际上传播的可能性较小。
As the novel coronavirus spread globally, a growing public panic was expressed over the internet. We examine the public discussion concerning COVID-19 on Twitter. We use a dataset of 67 million tweets from 12 million users collected between January 29, 2020 and March 4, 2020. We categorize users based on their home countries, social identities, and political orientation. We find that news media, government officials, and individual news reporters posted a majority of influential tweets, while the most influential ones are still written by regular users. Tweets mentioning "fake news" URLs and disinformation story-lines are also more likely to be spread by regular users. Unlike real news and normal tweets, tweets containing URLs pointing to "fake news" sites are most likely to be retweeted within the source country and so are less likely to spread internationally.
