[0033] POI recommendation based on graph embedding includes four parts: user embedding vector modeling, POI embedding vector modeling, rating prediction, and model training. The invention constructs user-POI interaction graph and social graph respectively, and then uses interaction aggregator to learn and generate potential vector of POI space on user-POI interaction graph, and social aggregator learns to generate potential vector of social space on social graph. Finally, the late...
