摘要:

尽管基于图像的传播对网络话语产生了影响,但图像在虚假信息中所扮演的角色仍然没有得到很好的理解。在本文中,我们提出了第一个大规模的研究fauxtography,分析使用操纵或误导性的图像在网上社区的新闻讨论。首先,我们开发了一个用于检测fauxtography的计算管道,并识别了Twitter,4chan和Reddit上讨论的超过61,000个fauxtography实例。然后,我们研究了发布虚假内容如何影响社交媒体上帖子的参与度,发现包含它的帖子以重新分享,喜欢和评论的形式获得更多的互动。最后,我们发现,fauxtography图像往往变成模因的网络社区。我们的研究结果表明,有效缓解虚假信息需要考虑图像,并强调了处理基于图像的虚假信息的一些挑战。

英文摘要:

Despite the influence that image-based communication has on online discourse, the role played by images in disinformation is still not well understood. In this paper, we present the first large-scale study of fauxtography, analyzing the use of manipulated or misleading images in news discussion on online communities. First, we develop a computational pipeline geared to detect fauxtography, and identify over 61k instances of fauxtography discussed on Twitter, 4chan, and Reddit. Then, we study how posting fauxtography affects engagement of posts on social media, finding that posts containing it receive more interactions in the form of re-shares, likes, and comments. Finally, we show that fauxtography images are often turned into memes by Web communities. Our findings show that effective mitigation against disinformation need to take images into account, and highlight a number of challenges in dealing with image-based disinformation.
