Abstract Combining graph convolutional networks(GCN) and auto encoder(AE), a scalable semi-supervised network representation learning model, Semi-GCNAE, is proposed to preserve the network structure information and node feature information. GCN is utilized to capture the structure and feature information of all nodes in K-order neighborhood of the node. The captured information is utilized as the input of AE. The K-order neighborhood information captured by GCN is extracted and the dimension is reduced nonlinearly by AE. The cluster structure information of nodes is preserved by combining Laplacian feature mapping. The ensemble learning method is introduced to train GCN and AE jointly. Therefore, the learned low-dimensional vector representation of nodes can retain both network structure information and node feature information. Extensive evaluation on five real datasets shows that the low-dimensional vector representation of nodes acquired by the proposed model preserves the structure and characteristics of the network effectively. And it generates better performance in node classification, visualization and network reconstruction tasks.
