Ruoyu Xu, Gaoxiang Li

AI总结:

本文系统比较了传统离线模型与GPT-4、Claude、Gemini等在线大语言模型在实时虚假新闻检测中的表现,发现在线LLM更能适应动态错误信息模式,并强调向在线模型过渡对构建可扩展检测系统的重要性。

摘要:

虚假新闻检测在当今快速演变的数字环境中仍然是一项关键挑战,错误信息的传播速度比以往任何时候都快。传统的虚假新闻检测模型通常依赖静态数据集和辅助信息,例如元数据或社交媒体互动,这限制了它们对实时场景的适应能力。大语言模型(LLMs)的最新进展在应对这些挑战方面展现出巨大潜力,因为它们拥有广泛的预训练知识,并且能够在不依赖辅助数据的情况下分析文本内容。然而,许多基于大语言模型的方法仍然建立在静态数据集之上,对其实时处理能力的探索十分有限。本文对传统离线模型和最先进的大语言模型在实时虚假新闻检测中的表现进行了系统性评估。我们展示了现有离线模型的局限性,包括它们无法适应动态变化的错误信息模式。此外,我们表明具备在线能力的新一代大语言模型,如GPT-4、Claude和Gemini,更适合在实时环境中检测新出现的虚假新闻。我们的研究结果强调了从离线大语言模型向在线大语言模型过渡对于实时虚假新闻检测的重要性。此外,大语言模型的公开可及性增强了其可扩展性,并使打击错误信息所需的工具更加民主化。通过利用实时数据,我们的工作标志着向更具适应性、更有效且可扩展的虚假新闻检测系统迈出了重要一步。

英文摘要:

Fake news detection remains a critical challenge in today's rapidly evolving digital landscape, where misinformation can spread faster than ever before. Traditional fake news detection models often rely on static datasets and auxiliary information, such as metadata or social media interactions, which limits their adaptability to real-time scenarios. Recent advancements in Large Language Models (LLMs) have demonstrated significant potential in addressing these challenges due to their extensive pre-trained knowledge and ability to analyze textual content without relying on auxiliary data. However, many of these LLM-based approaches are still rooted in static datasets, with limited exploration into their real-time processing capabilities. This paper presents a systematic evaluation of both traditional offline models and state-of-the-art LLMs for real-time fake news detection. We demonstrate the limitations of existing offline models, including their inability to adapt to dynamic misinformation patterns. Furthermore, we show that newer LLM models with online capabilities, such as GPT-4, Claude, and Gemini, are better suited for detecting emerging fake news in real-time contexts. Our findings emphasize the importance of transitioning from offline to online LLM models for real-time fake news detection. Additionally, the public accessibility of LLMs enhances their scalability and democratizes the tools needed to combat misinformation. By leveraging real-time data, our work marks a significant step toward more adaptive, effective, and scalable fake news detection systems.
