User tag optimization method and device, equipment and storage medium

The invention discloses a user tag optimization method, device and equipment and a computer readable storage medium, and the user tag optimization method comprises the steps: obtaining industry interest information corresponding to each terminal user at preset time intervals, constructing an interest topological data set according to the industry interest information, and storing the interest topological data set in a database; the interest topological data set comprises user nodes, industry nodes and label nodes, and the interest topological data set is characterized by an adjacent matrix and a feature matrix; inputting the adjacency matrix and the characteristic matrix representation into a graph auto-encoder to obtain vector representation corresponding to each user node; performing common clustering on the user nodes according to the vector representation to generate a plurality of common clusters; and determining the user nodes located in the clustering center in each common cluster, and optimizing the u
