Overview

With the explosive growth of false information on social media platforms, the automatic detection of multimodal false information has received increasing attention. Recent research has significantly contributed to multimodal information exchange and fusion, with many methods attempting to integrate unimodal features to generate multimodal news representations. However, they still need to fully explore the hierarchical and complex semantic correlations between different modal contents, severely limiting their performance detecting multimodal false information. This work proposes a two-stage detection framework for multimodal false information detection, called ASMFD, which is based on image aesthetic similarity to segment and explores the consistency and inconsistency features of images and texts. Specifically, we first use the Contrastive Language-Image Pre-training (CLIP) model to learn the relationship between text and images through label awareness and train an image aesthetic attribute scorer using an aesthetic attribute dataset. Then, we calculate the aesthetic similarity between the image and related images and use this similarity as a threshold to divide the multimodal correlation matrix into consistency and inconsistency matrices. Finally, the fusion module is designed to identify essential features for detecting multimodal false information. In extensive experiments on four datasets, the performance of the ASMFD is superior to state-of-the-art baseline methods.
