对比中英文奥运报道话语差异，揭示媒体偏见与情感倾向
Comparative Study on the Discourse Meaning of Chinese and English Media in the Paris Olympics Based on LDA Topic Modeling Technology and LLM Prompt Engineering
- 用LDA与大模型提示工程分析两国媒体话题构建
- 中文重精神与技术，英文侧重女运动员与奖牌争议
- 发现中英文在开幕式、女拳击等议题上态度语义不同
本研究结合主题建模、大语言模型提示工程与语料短语学方法，分析中英文媒体对巴黎奥运会的报道，探讨其话语建构与态度意义的异同。共同话题包括开幕式、运动员表现与赞助品牌。中文媒体聚焦特定项目、体育精神、兴奋剂争议及新技术应用；英文媒体则更关注女性运动员、奖牌成绩与参赛资格争议。中文报道在描述开幕式与体育精神时更频繁出现介词共现，并呈现正向语义倾向；英文报道在报道女性运动员时具正向语义倾向，但在预测开幕式反响及讨论女子拳击争议时呈现负向语义倾向。
原文摘要 · Abstract (English)
This study analyzes Chinese and English media reports on the Paris Olympics using topic modeling, Large Language Model (LLM) prompt engineering, and corpus phraseology methods to explore similarities and differences in discourse construction and attitudinal meanings. Common topics include the opening ceremony, athlete performance, and sponsorship brands. Chinese media focus on specific sports, sports spirit, doping controversies, and new technologies, while English media focus on female athletes, medal wins, and eligibility controversies. Chinese reports show more frequent prepositional co-occurrences and positive semantic prosody in describing the opening ceremony and sports spirit. English reports exhibit positive semantic prosody when covering female athletes but negative prosody in predicting opening ceremony reactions and discussing women's boxing controversies.
