Abstract: In recent years,network representation learning has received more and more attention as an effective method for analyzing heterogeneous information networks by representing nodes in a low-dimensional space.Random walk based methods are currently popular methods to learn network embedding,however,most of these methods are based on shallow neural networks,which make it difficult to capture heterogeneous network structure information.The graph convolutional network (GCN) is a popular method for deep learning of graphs,which is known to be capable of better exploitation of network topology,but current design of GCN is intended for homogenous networks,ignoring the rich semantic information in the network.In order to effectively mine the semantic information and highly nonlinear network structure information in heterogeneous information networks,this paper proposes a heterogeneous network representation learning algorithm based on graph convolution of fusion meta-path(MG2vec)to improve the effect of network representation.Firstly,the algorithm obtains rich semantic information in heterogeneous information networks through relevance measurement based on meta-paths.Then the graph convolution network is used for deep learning to capture the characteristics of nodes and neighbor nodes,to make up for the deficiency of shallow model in capturing the information of the network structure,so as to better integrate rich semantic information and structural information into the low-dimensional node representation.Experiments are carried out on DBLP and IMDB,compared with DeepWalk,node2vec and Metapath2vec classical algorithms,the proposed MG2vec algorithm has higher classification accuracy and better performance in multi-label classification tasks,the precision and Macro-F1 value can be respectively up to 94.49% and 94.16%,and the both of values are up to 26.05% and 28.73% higher respectively than DeepWalk.The experimental results show that the performance of MG2vec algorithm is better than that of classical network representation learning algorithms,and MG2vec has better heterogeneous information network representation effect.
