Abstract
MSGT-GNN
, a graph knowledge transfer model for efficient graph link prediction from multiple source graphs. MSGT-GNN
consists of two components: the Intra-Graph Encoder, which embeds latent graph features of system entities into vectors; and the graph transferor, which utilizes graph attention mechanism to learn and optimize the embeddings of corresponding entities from multiple source graphs, in both node level and graph level. Experimental results on multiple real-world datasets from various domains show that MSGT-GNN
outperforms other baseline approaches in the link prediction and demonstrate the merit of attentive graph knowledge transfer and the effectiveness of MSGT-GNN
.
