使用主题建模分析围绕 OpenAI 文生视频模型“Sora”的公共话语
Analysing the Public Discourse around OpenAI's Text-To-Video Model 'Sora' using Topic Modeling
AI总结：
本研究利用 LDA 主题建模分析 1,827 条 Reddit 评论，揭示公众围绕 OpenAI 文生视频模型 Sora 的四大主题：AI 影响、公众担忧、艺术创作及媒体应用，为理解生成式 AI 的公众认知提供了框架。
摘要：
OpenAI 最近推出的文生视频模型 Sora 已在在线社区中引发了广泛的公共讨论。本研究旨在通过主题建模分析，揭示围绕 Sora 的主导主题和叙事。我们收集了来自五个相关 subreddit（r/OpenAI、r/technology、r/singularity、r/vfx 和 r/ChatGPT）的 1,827 条 Reddit 评论作为语料库。这些评论是在 2024 年 2 月 Sora 发布后的两个月内收集的。在对数据进行预处理后，采用潜在狄利克雷分配（LDA）提取了四个关键主题：1）Sora 讨论中的人工智能影响与趋势；2）关于 Sora 的公众意见与担忧；3）使用 Sora 进行艺术表达与视频创作；4）Sora 在媒体与娱乐领域的应用。包括词云、条形图和 t-SNE 聚类在内的可视化方法，为理解主题关键词的重要性以及评论在各主题间的分布提供了见解。结果突出了围绕 Sora 对行业和就业的潜在影响、公众情绪与伦理关切、创意应用以及媒体和娱乐领域用例的显著叙事。尽管本研究仅限于特定时间段内的 Reddit 数据，但它为通过在线话语分析理解新兴生成式人工智能技术的公众认知提供了一个框架。
英文摘要：
The recent introduction of OpenAI's text-to-video model Sora has sparked widespread public discourse across online communities. This study aims to uncover the dominant themes and narratives surrounding Sora by conducting topic modeling analysis on a corpus of 1,827 Reddit comments from five relevant subreddits (r/OpenAI, r/technology, r/singularity, r/vfx, and r/ChatGPT). The comments were collected over a two-month period following Sora's announcement in February 2024. After preprocessing the data, Latent Dirichlet Allocation (LDA) was employed to extract four key topics: 1) AI Impact and Trends in Sora Discussions, 2) Public Opinion and Concerns about Sora, 3) Artistic Expression and Video Creation with Sora, and 4) Sora's Applications in Media and Entertainment. Visualizations including word clouds, bar charts, and t-SNE clustering provided insights into the importance of topic keywords and the distribution of comments across topics. The results highlight prominent narratives around Sora's potential impact on industries and employment, public sentiment and ethical concerns, creative applications, and use cases in the media and entertainment sectors. While limited to Reddit data within a specific timeframe, this study offers a framework for understanding public perceptions of emerging generative AI technologies through online discourse analysis.
