Content recommendation method and device and related product

The invention discloses a content recommendation method and device and a related product. Constructing an initial hypergraph according to the interaction data of the multiple users and the multiple items of content and initializing a user representation propagation sequence; updating the initial hypergraph through expansion of interaction data, and performing K-1 rounds of propagation on the basis of the updated hypergraph on the basis of the initialized user representation propagation sequence; obtaining a user representation matrix corresponding to the plurality of users according to a user representation propagation sequence obtained after the (K-1) th round of propagation is ended; and performing content recommendation based on the user representation matrix and the content representation matrix corresponding to the multiple items of content. The user representation propagation sequence obtained after K-1 times of propagation is finished is increased accurately, and then the accuracy of the coding effect
