论文摘要
俄罗斯入侵乌克兰的报道在西方，俄罗斯和中国媒体生态系统之间差异很大，其中三者中宣传，虚假信息和叙事旋转。通过利用归一化的相互信息指标，差异情绪分析，Word2Vec模型以及部分标记的Dirichlet分配，我们对这三个新闻生态系统之间的覆盖率差异进行了定量分析。我们发现，尽管西方媒体的渠道集中在战争的军事和人道主义方面，但俄罗斯媒体仍集中在据称“特殊军事行动”的理由上，例如在乌克兰的“生物武器”和“新纳粹分子”中的存在，中国新闻媒体集中在冲突的外交和经济后果上。在几个中国媒体的文章中发现了几种俄罗斯虚假信息叙事的存在，我们终于衡量了俄罗斯媒体在中国媒体的新闻报道，微博帐户和Twitter帐户中影响中国的报道的程度。我们的分析表明，自从俄罗斯入侵乌克兰以来，中国州媒体越来越引用俄罗斯媒体作为新闻来源，并传播了俄罗斯的虚假信息叙事。
The coverage of the Russian invasion of Ukraine has varied widely between Western, Russian, and Chinese media ecosystems with propaganda, disinformation, and narrative spins present in all three. By utilizing the normalized pointwise mutual information metric, differential sentiment analysis, word2vec models, and partially labeled Dirichlet allocation, we present a quantitative analysis of the differences in coverage amongst these three news ecosystems. We find that while the Western press outlets have focused on the military and humanitarian aspects of the war, Russian media have focused on the purported justifications for the "special military operation" such as the presence in Ukraine of "bio-weapons" and "neo-nazis", and Chinese news media have concentrated on the conflict's diplomatic and economic consequences. Detecting the presence of several Russian disinformation narratives in the articles of several Chinese outlets, we finally measure the degree to which Russian media has influenced Chinese coverage across Chinese outlets' news articles, Weibo accounts, and Twitter accounts. Our analysis indicates that since the Russian invasion of Ukraine, Chinese state media outlets have increasingly cited Russian outlets as news sources and spread Russian disinformation narratives.
