加密平台上打击错误信息的提示：以WhatsApp上的2019年印度大选为例
Tiplines to Combat Misinformation on Encrypted Platforms: A Case Study of the 2019 Indian Election on WhatsApp
摘要：
目前还没有简单的方法来大规模地检查WhatsApp和其他端到端加密平台上的内容。在本文中，我们分析了一个众包的“tipline”，通过它用户可以提交内容（“提示”），他们希望事实检查的有用性。我们将2019年印度全国大选期间发送到WhatsApp tipline的提示与同期在WhatsApp和其他社交媒体平台上的大型公共团体中传播的消息进行了比较。我们发现，tiplines是WhatsApp对话的一个非常有用的镜头：发送到tipline的消息和图像中有很大一部分与公共WhatsApp群组和其他社交媒体上共享的内容相匹配。我们的分析还表明，tiplines很好地覆盖了最受欢迎的内容，并且大多数此类内容通常在出现在大型公共WhatsApp群组之前被共享到tipline。总的来说，我们的研究结果表明，tiplines可以成为发现事实核查内容的有效来源。
英文摘要：
There is currently no easy way to fact-check content on WhatsApp and other end-to-end encrypted platforms at scale. In this paper, we analyze the usefulness of a crowd-sourced "tipline" through which users can submit content ("tips") that they want fact-checked. We compare the tips sent to a WhatsApp tipline run during the 2019 Indian national elections with the messages circulating in large, public groups on WhatsApp and other social media platforms during the same period. We find that tiplines are a very useful lens into WhatsApp conversations: a significant fraction of messages and images sent to the tipline match with the content being shared on public WhatsApp groups and other social media. Our analysis also shows that tiplines cover the most popular content well, and a majority of such content is often shared to the tipline before appearing in large, public WhatsApp groups. Overall, our findings suggest tiplines can be an effective source for discovering content to fact-check.
