An example of a sample post regarding GPT-3.

ChatGPT has demonstrated impressive abilities and impacted various aspects of human society since its creation, gaining widespread attention from different social spheres. This study aims to comprehensively assess public perception of ChatGPT on Reddit. The dataset was collected via Reddit, a social media platform, and includes 23,733 posts and comments related to ChatGPT. Firstly, to examine public attitudes, this study conducts content analysis utilizing topic modeling with the Latent Dirichlet Allocation (LDA) algorithm to extract pertinent topics. Furthermore, sentiment analysis categorizes user posts and comments as positive, negative, or neutral using Textblob and Vader in natural language processing. The result of topic modeling shows that seven topics regarding ChatGPT are identified, which can be grouped into three themes: user perception, technical methods, and impacts on society. Results from the sentiment analysis show that 61.6% of the posts and comments hold favorable opinions on ChatGPT. They emphasize ChatGPT’s ability to prompt and engage in natural conversations with users, without relying on complex natural language processing. It provides suggestions for ChatGPT developers to enhance its usability design and functionality. Meanwhile, stakeholders, including users, should comprehend the advantages and disadvantages of ChatGPT in human society to promote ethical and regulated implementation of the system.ChatGPT自问世以来展现出卓越能力，对人类社会诸多领域产生深远影响，受到社会各界广泛关注。本研究旨在全面评估Reddit平台上公众对ChatGPT的认知。本数据集通过社交媒体平台Reddit采集，包含23733条与ChatGPT相关的帖子与评论。首先，为考察公众态度，本研究采用基于潜在狄利克雷分配（Latent Dirichlet Allocation，LDA）算法的主题建模开展内容分析，以提取相关主题。此外，本研究借助自然语言处理（Natural Language Processing，NLP）工具Textblob与Vader，将用户发布的帖子及评论划分为积极、消极与中性三类，完成情感分析。主题建模结果显示，本研究共识别出7个与ChatGPT相关的主题，可归纳为三大类别：用户认知、技术方法与社会影响。情感分析结果表明，61.6%的帖子与评论对ChatGPT持积极态度，用户们着重肯定了其无需依赖复杂自然语言处理技术，即可生成自然对话并与用户实现交互的能力。本研究可为ChatGPT开发者优化其可用性设计与功能提供参考依据。同时，包括普通用户在内的各利益相关方，应全面认知ChatGPT在人类社会中的利弊，以推动该系统实现伦理化、规范化的落地应用。
