YouTube推广阴谋视频的纵向分析
A Longitudinal Analysis of YouTube's Promotion of Conspiracy Videos
摘要：
阴谋论在社交媒体上蓬勃发展，人们担心这些内容正在助长虚假信息的传播，支持极端主义意识形态，并在某些情况下导致暴力。在立法者和公众越来越多的审查和压力下，YouTube宣布努力改变其推荐算法，以便最令人震惊的阴谋视频被降级和妖魔化。为了验证这一说法，我们开发了一个分类器，用于自动确定视频是否是阴谋的（例如，登月是假的，吉萨金字塔是外星人建造的，世界末日的预言等等）。我们将这个分类器与YouTube的watch-next算法在一千多个流行的信息频道上的仿真相结合，以获得YouTube积极推广的视频的长达一年的图片。我们还得到了阴谋论中所谓的过滤气泡效应的趋势。
英文摘要：
Conspiracy theories have flourished on social media, raising concerns that such content is fueling the spread of disinformation, supporting extremist ideologies, and in some cases, leading to violence. Under increased scrutiny and pressure from legislators and the public, YouTube announced efforts to change their recommendation algorithms so that the most egregious conspiracy videos are demoted and demonetized. To verify this claim, we have developed a classifier for automatically determining if a video is conspiratorial (e.g., the moon landing was faked, the pyramids of Giza were built by aliens, end of the world prophecies, etc.). We coupled this classifier with an emulation of YouTube's watch-next algorithm on more than a thousand popular informational channels to obtain a year-long picture of the videos actively promoted by YouTube. We also obtained trends of the so-called filter-bubble effect for conspiracy theories.
