Detecting AI-Generated Content on Social Media with Multi-modal Language Models
利用多模态语言模型检测社交媒体上的 AI 生成内容
Abstract: Generative AI has enabled the creation of photorealistic images and videos that are increasingly disseminated on social media, often used for spam, misinformation, manipulation, and fraud. Existing AI-generated content (AIGC) detection methods face challenges including poor generalization to new generation models, reliance on single modalities, and lack of interpretable explanations.
摘要： 生成式 AI 使得创建逼真的图像和视频成为可能，这些内容正日益在社交媒体上传播，并常被用于垃圾信息、虚假信息、操纵舆论和欺诈。现有的 AI 生成内容（AIGC）检测方法面临诸多挑战，包括对新型生成模型的泛化能力较差、过度依赖单一模态，以及缺乏可解释的说明。
We present our pipeline that mitigates these issues by continuously curating diverse multi-modal social media data and training a compact vision-language model for detection and explanation. Our model achieves state-of-the-art detection performance on public benchmarks and demonstrates robust detection and explanation capabilities on internal social media datasets across multiple platforms.
我们提出了一套解决方案，通过持续整理多样化的多模态社交媒体数据，并训练一个紧凑的视觉-语言模型来进行检测和解释，从而缓解了上述问题。我们的模型在公开基准测试中达到了最先进的检测性能，并在多个平台的内部社交媒体数据集上展现了强大的检测与解释能力。
We deployed our model for post recommendation on social media platforms and observed positive downstream impacts on user engagement, demonstrating that it is feasible to perform effective AIGC detection in dynamic, real-world social media environments.
我们将该模型部署于社交媒体平台的帖子推荐系统中，并观察到其对用户参与度产生了积极的下游影响，这证明了在动态的现实社交媒体环境中进行有效的 AIGC 检测是切实可行的。
