This paper presents cross-domain recommendation based on multilayer graph analysis using subgraph representation. The proposed method constructs two graphs in source and target domains utilizing user-item embedding and trains link relationships between the users’ embedding features on each above graph via graph convolutional networks considering subgraph representation. Thus, the proposed method can obtain features with high representation ability, and this is the main contribution of this paper. Then the proposed method can estimate the user’s embedding features in the target domain from those in the source domain and recommend items to users by using the estimated features. Experiments on real-world e-commerce datasets verify the effectiveness of the proposed method.
