Embodiment Construction
[0048] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.
[0049] The working principle of the present invention includes: first preprocessing the data set to obtain the social relationship between users, user-commodity interaction history data and product category data, and performing multi-level graph sampling and constructing heterogeneous graphs, and inputting the constructed heterogeneous graphs Go to the trained heterogeneous graph network for recommendation prediction.
[0050] A recommendation method based on a heterogeneous graph neural network, including steps:
[0051] S1. Build a data set, collect data sets with social relationships between users, user-product interaction history data, and product category information in scenarios such as e-commerce and review websites, and filter inva...
