Abstract: In order to identify fake news on social media platforms timely and accurately,a BGMA fake news detection model was constructed.The BGMA model at first used the BERT model to extract the semantic features of the textual content,and then the GAT model was used to capture the complex associations and dynamic changes between user behaviors. Finall,the two features were weighted and fused by introducing a multi-attention mechanism.The results showed that the detection performance of the BGMA model could improves the accuracy by 4.06% on the PolitiFact dataset and 19.73% on the GossipCop dataset compared with the BERT-LSTM model. Compared with the GCNFC model, the accuracy was improved by 10.59% on the PolitiFact dataset and 10.47% on the GossipCop dataset. The practical test result proved that the BGMA model could effectively combine text and user features and achieve better fake news detection results.
