FakeNewsGPT4 proposes a novel framework that leverages world knowledge from Large Vision-Language Models (LVLMs) and augments them with forgery-specific knowledge to address the domain shift issue in multimodal fake news detection. The framework involves acquiring two types of forgery-specific knowledge, semantic correlation, and artifact trace, and merging them into LVLMs. It also incorporates candidate answer heuristics and soft prompts to enhance input informativeness. Extensive experiments on the DGM4 dataset demonstrate superior cross-domain performance compared to previous methods.
