Social media content propagation prediction method and device

The invention discloses a social media content propagation prediction method and device, and the method comprises the steps: obtaining historical social media content and historical forwarding relation data corresponding to the historical social media content, and carrying out the construction according to the historical social media content and the historical forwarding relation data, and obtaining a cascade structure diagram corresponding to a content propagation process; time features are set for nodes in the cascade structure diagram through a Transform network based on an attention mechanism, and a first processing result is obtained; processing the cascade structure diagram in a node dimension and a time dimension by using a variational encoder to obtain a second processing result; and according to the to-be-predicted social media content, the first processing result and the second processing result, predicting propagation data of the to-be-predicted social media content in the specified prediction time
