标题： Truth Sleuth and Trend Bender: AI Agents to fact-check YouTube videos and influence opinions

摘要： 错误信息在当今的数字世界中构成重大威胁，常常通过YouTube等平台迅速传播。 本文介绍了一种新的方法来对抗错误信息，通过开发一个由人工智能驱动的系统，该系统不仅能够对YouTube视频中的声明进行事实核查，还能积极地在评论区与用户互动，并挑战误导性叙述。 我们的系统包括两个主要代理：真相侦探和趋势引导者。 真相侦探从YouTube视频中提取声明，使用检索增强生成（RAG）方法——参考维基百科、谷歌搜索、谷歌事实核查等来源——以准确评估其真实性并生成细致且全面的报告。 通过严格的提示工程，趋势引导者利用这份报告以及经过筛选的相关文章语料库，生成有见解且具有说服力的评论，旨在激发有益的辩论。 通过精心设置的自我评估循环，该代理能够迭代改进其风格并优化其输出。 我们通过在现有基准数据集上的实验和在YouTube上的实际部署来展示系统的功能，展示了其吸引用户并可能影响观点的潜力。 我们的研究结果突显了我们事实核查代理的高准确性，并证实了人工智能驱动的干预措施在对抗错误信息和促进更知情的在线空间方面的潜力。 显示英文摘要

摘要： Misinformation poses a significant threat in today's digital world, often spreading rapidly through platforms like YouTube. This paper introduces a novel approach to combating misinformation by developing an AI-powered system that not only fact-checks claims made in YouTube videos but also actively engages users in the comment section and challenge misleading narratives. Our system comprises two main agents: Truth Sleuth and Trend Bender. Truth Sleuth extracts claims from a YouTube video, uses a Retrieval-Augmented Generation (RAG) approach - drawing on sources like Wikipedia, Google Search, Google FactCheck - to accurately assess their veracity and generates a nuanced and comprehensive report. Through rigorous prompt engineering, Trend Bender leverages this report along with a curated corpus of relevant articles to generate insightful and persuasive comments designed to stimulate a productive debate. With a carefully set up self-evaluation loop, this agent is able to iteratively improve its style and refine its output. We demonstrate the system's capabilities through experiments on established benchmark datasets and a real-world deployment on YouTube, showcasing its potential to engage users and potentially influence perspectives. Our findings highlight the high accuracy of our fact-checking agent, and confirm the potential of AI-driven interventions in combating misinformation and fostering a more informed online space.
