Fake News Detection with Heterogeneous Transformer

1 code implementation6 May 2022 Tianle Li, Yushi Sun, Shang-Ling Hsu, Yanjia Li, Raymond Chi-Wing Wong

The heterogeneity in both news content and the relationship with other entities in social networks brings challenges to designing a model that comprehensively captures the local multi-modal semantics of entities in social networks and the global structural representation of the propagation patterns, so as to classify fake news effectively and accurately.
