Abstract The key to dynamic link prediction is modeling network dynamics and extracting local structural features. Therefore, a method for dynamic network link prediction based on node representation and subgraph structure is proposed. To model node evolution dynamics, the node2vec model is introduced, and the node representations in historical snapshots are concatenated in temporal order. To model the local subgraph structure information, a graph isomorphism algorithm is employed to encode the topology structure of the local subgraph. In each historical snapshot, the node vectors of the target node pair and the topology structure of the local subgraph are fused by the ultimate feature representation of the target link. Extensive experiments demonstrate that the proposed method achieves better performance.
