论文摘要
WhatsApp是传播新闻和谣言的关键媒介，通常是作为图像共享的。我们研究了印度的大量以政治为导向的WhatsApp团体，重点是在2019年印度全国大选之前的时期。通过标记随机图像和流行图像的样本，我们发现大约13％的共享图像是已知的错误信息，大多数图像属于三种类型的图像。机器学习方法可用于预测病毒图像是否是错误的信息，但由于内容随时间而变化而脆弱。
WhatsApp is a key medium for the spread of news and rumors, often shared as images. We study a large collection of politically-oriented WhatsApp groups in India, focusing on the period leading up to the 2019 Indian national elections. By labeling samples of random and popular images, we find that around 13% of shared images are known misinformation and most fall into three types of images. Machine learning methods can be used to predict whether a viral image is misinformation, but are brittle to shifts in content over time.
