Overview

In recent years, due to the massive amount of information on the web, the rumor detection on social media presents a significant challenge owing to online content’s noisy, dynamic, and often adversarial nature. This work introduces a model that leverages Graph Attention Networks (GAT) enhanced with adversarial and contrastive learning to improve rumor classification performance. Experimental results on the X Dataset (formerly Twitter) demonstrate that our integrated GAT+ADV+CL model achieves satisfactory performance across multiple classification evaluation metrics, while maintaining a relatively simple architecture compared to other recent complex graph-based approaches for rumor detection. These findings highlight the effectiveness of combining robustness and representation learning in tackling the challenge of misinformation detection.
