摘　　要：【目的】直观、全面地刻画元宇宙概念所引发的舆情态势及其变迁,为元宇宙相关政策与产业规划提供借鉴。【方法】基于2021年9月-2023年2月元宇宙相关微博文本数据,采用BERT模型和DTM模型抽取其语义和主题特征,借助K-means算法实现主题聚类,解读元宇宙话题的演化规律。【结果】大众对元宇宙的关注焦点发轫于非同质化代币(Non-Fungible Token,NFT)和游戏,随着数字产业的资本炒作,进一步引发文娱产业的跟进以及实体产业的尝试。而ChatGPT的出现则引发了大众对元宇宙产业现状、技术创新和应用展望的进一步探讨。【局限】未结合外文数据(如Twitter)对比分析国内外对元宇宙话题关注点的侧重、趋势等方面的差异。【结论】本研究从定量与宏观的角度解读了元宇宙相关话题的社会关注度特征及演化规律,对正确引导元宇宙网络舆情走向、避免舆论泡沫等工作具有一定参考借鉴意义。[Objective]This paper comprehensively examines the evolution of public opinion triggered by the metaverse concepts,which provides insights for metaverse-related policies and industry planning.[Methods]We retrieved Weibo textual posts on metaverse-related from September 2021 to February 2023.Then,we utilized BERT and DTM models to extract semantic and topic features.Third,we employed the K-means algorithm for topic clustering and explored their evolutionary patterns.[Results]The public attention on the metaverse originated around NFTs and gaming.With capital speculation within the digital industry,the entertainment and physical industries joined the race.The emergence of ChatGPT further prompted the public’s exploration of the status quo of the metaverse,technology innovation,and prospective applications.[Limitations]We did not include foreign language data from Twitter to compare the focus and trends of the metaverse topics among domestic and international users.[Conclusions]This study examines the characteristics and evolution of social attention on topics related to the meta-universe from quantitative and macro perspectives.It helps us regulate online public opinion in the meta-universe.
