The Graph Convolution Network (GCN) can adapt to graphs with different structures. However, most GCN-based models have difficulty effectively capturing the high-order similarity of the network. Simply adding a convolution layer will cause the output features to be too smooth and difficult to distinguish. Moreover, the deep neural network is more difficult to train. In this paper, multi-granularity structure and a GCN are combined to represent the node characteristics of the learning network. A multi-granularity structure-based network representation learning method, Multi-GS, is proposed. First, based on the idea of modularity clustering and granular computing, hierarchical multi-granularity space was used to replace the original single-layer network topology space. The GCN model was then used to learn the representation of granules in different coarse- and fine-granularity spaces. Finally, representations of the different grains were combined into representations of nodes in the original space from coarse to fine. Experimental results showed that multi-GS can capture a variety of structural information, including first-order and second-order similarity, intra-community similarity (high-order structure), and inter-community similarity (global structure). In most cases, using multi-granularity structure can improve the classification performance of node classification tasks.
