俄烏戰爭的輿論分析：兩岸網民的文字探勘研究
Public Opinion Analysis of Russia-Ukraine War based on Text Mining on China and Taiwan Netizens
摘要
社群媒體是現代社會發展的重要一環，隨著大眾對於網路使用程度的上升，網路上所發出的言論也成為人們所關注的對象。日常的議題討論，輾轉從生活移至網絡，這也讓重要事件發生後，網絡上的發言、辯論，往往成為與論風向的濫觴，而2022年2月底所突發的俄烏戰爭亦是如此。本文研究文本取自臺灣論壇「PTT」與「Dcard」以及中國大陸的「Weibo」為研究標的，並擷取所有自開戰以來相關「俄羅斯、烏克蘭」等關鍵字的相關文章。欲透過文字探勘解析海量網民評論與文章，瞭解兩岸網民對於他國戰爭看法之異同。由於戰爭瞬息萬變，將使用評論之時間趨勢與主題模型，查看兩岸網民於不同時間的主題轉變，並使用情感分析找出其立場之變化過程。 研究最後發現，針對俄烏戰爭中重點事件的爆發，臺灣的輿論會將其轉為關注統獨問題，中國大陸則多為討論官方宣傳上美國在烏生物實驗室以及烏克蘭納粹問題。整體立場上的態度，台灣社群較支持烏克蘭，中國大陸社群較支持俄羅斯，其結果與研究機構的民意調查結果相符。最後，依據研究呈現，兩岸輿論的最大公約數為世界和平，但於情感立場趨勢上來看，臺海兩岸網民對於世界和平之定義多有不同。

The daily discussion of topics has moved from life to the internet, making speeches and debates on the internet become more like media framing when a memorable event happens. It is similar to the Russian-Ukraine war that broke out at the end of February 2022. The research data of this paper is taken from Taiwan forums "PTT, Dcard" and "Weibo" in mainland China as the research object, retrieving all relevant articles related to keywords 'Russia, Ukraine', Etc. since the war started. This paper wants to analyze comments and articles through text mining, to understand the differences in the views of netizens on both sides of the strait. Since the war is changing rapidly, we use the time trend and topic model to find the topic and use sentiment analysis to figure out the change in positions. In the end, the study found that in response to the outbreak of critical events in the Russian-Ukrainian war. Taiwanese public opinion turned its attention to the issue of reunification and independence, and mainland China mainly discussed the official propaganda of the U.S. biological laboratory in Ukraine and the issue of Nazism in Ukraine. Regarding overall perspectives, the Taiwanese community stands more with Ukrainian, and the Chinese community stands more with Russian. The results are in line with the research institute's opinion polls conclusions. Finally, according to the research, world peace is the most significant common denominator of public opinion on both sides of the Taiwan Strait. However, in terms of their emotional stance trends, netizens on both sides of the Taiwan Strait have different definitions of world peace.
