论文摘要
本文定量比较了乌克兰相关的虚假信息及其相应的揭穿，首先是考虑重新启动，答复和收藏夹，这表明，尽管平台努力努力，乌克兰与乌克兰相关的虚假信息仍在越来越宽，但仍比其扣押差异。接下来，使用Granger因果关系测试，IMPULSE响应分析和预测误差方差分解进行双向事后分析，该分析表明，扣押的扩散对减少乌克兰相关的虚假信息有积极影响，尽管最终并非立即。最后，该论文调查了与乌克兰相关的虚假信息的主要主题及其时空分布。关于揭穿，我们还确定，大约18％的事实核对案件正在揭穿揭穿的主张，这些主张已经通过另一种语言进行了事实检查。后者的发现重点介绍了在事实检查器之间进行更好合作的机会，因此他们可以通过翻译，引用和早期出版在线受益并扩大彼此的揭穿。
This paper compares quantitatively the spread of Ukraine-related disinformation and its corresponding debunks, first by considering re-tweets, replies, and favourites, which demonstrate that despite platform efforts Ukraine-related disinformation is still spreading wider than its debunks. Next, bidirectional post-hoc analysis is carried out using Granger causality tests, impulse response analysis and forecast error variance decomposition, which demonstrate that the spread of debunks has a positive impact on reducing Ukraine-related disinformation eventually, albeit not instantly. Lastly, the paper investigates the dominant themes in Ukraine-related disinformation and their spatiotemporal distribution. With respect to debunks, we also establish that around 18% of fact-checks are debunking claims which have already been fact-checked in another language. The latter finding highlights an opportunity for better collaboration between fact-checkers, so they can benefit from and amplify each other's debunks through translation, citation, and early publication online.
