RAGAT-Mind: A Multi-Granular Modeling Approach for Rumor Detection Based on MindSpore
It addresses the pressing challenge of detecting false information on social media platforms, offering a practical solution with strong performance for real-world applications.
This paper tackles the problem of rumor detection on social media by proposing RAGAT-Mind, a multi-granular modeling approach for Chinese text, which achieves 99.2% accuracy and a macro-F1 score of 0.9919 on the Weibo1-Rumor dataset.
As false information continues to proliferate across social media platforms, effective rumor detection has emerged as a pressing challenge in natural language processing. This paper proposes RAGAT-Mind, a multi-granular modeling approach for Chinese rumor detection, built upon the MindSpore deep learning framework. The model integrates TextCNN for local semantic extraction, bidirectional GRU for sequential context learning, Multi-Head Self-Attention for global dependency focusing, and Bidirectional Graph Convolutional Networks (BiGCN) for structural representation of word co-occurrence graphs. Experiments on the Weibo1-Rumor dataset demonstrate that RAGAT-Mind achieves superior classification performance, attaining 99.2% accuracy and a macro-F1 score of 0.9919. The results validate the effectiveness of combining hierarchical linguistic features with graph-based semantic structures. Furthermore, the model exhibits strong generalization and interpretability, highlighting its practical value for real-world rumor detection applications.
