Embodiment Construction
[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0051] Taking the Sina Weibo data set as an example to provide a specific implementation method of the present invention, the overall framework of the method is as follows figure 1 and figure 2 shown. The entire algorithm process includes three steps: building a user-level social network, a two-stream graph convolutional network module, and a topic inference module based on a variational autoencoder.
[0052] Specific steps are as follows:
[0053] (1) Build a user-level social network:
[0054] The present invention uses the public Sina Weibo data set. This dataset collects relevant microblogs covering 50 hot topics in May, June and July 2014. The present invention uses these ...
