Document Type and Number:
WIPO Patent Application WO/2023/045378
Kind Code:
A1
Abstract:
Provided are a method and a device for recommending item information to a user, a storage medium, and a program product, relating to data processing technology. The method comprises: acquiring a preset topological graph representing association relationships between users and items, and update data used to update the preset topological graph; updating an edge in the preset topological graph according to the update data, to obtain an updated topological graph; acquiring a vector model obtained by pre-training and corresponding to the preset topological graph, and updating a vector of any node in the topological graph according to the updated topological graph and the acquired vector model, the vector being used to represent a feature of the node; and according to vectors of each node, determining an item node similar to a user node, and recommending item information of the similar item node to a user corresponding to the user node. In the provided solution, a node vector can be quickly updated on the basis of update data, so that information can be recommended to the user more accurately on the basis of the updated node vector.
