[0054] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0055] The present application discloses a recommendation algorithm based on knowledge graph, which includes the following steps: constructing a knowledge graph based on an application scenario; constructing a KGRN model based on GNN; inputting the knowledge graph into the KGRN model to obtain an embedding vector, and outputting the user's preference for items according to the embedding vector Recommendation index of the degree; recommend operation to users according to the recommendation index. The recommendation algorithm based on the knowledge graph of the present application constructs a high-quality knowledge graph according to the specific recommended scenario. After obtaining the historical data of the interaction between the user and the item, the relevant information of the user, and the relevant attributes of the item in the recommend...
