Path-aware Siamese Graph Neural Network for Link Prediction. (arXiv:2208.05781v2 [cs.LG] UPDATED)

In this paper, we propose a Path-aware Siamese Graph neural network(PSG) for
link prediction tasks. First, PSG captures both nodes and edge features for
given two nodes, namely the structure information of k-neighborhoods and relay
paths information of the nodes. Furthermore, a novel multi-task GNN framework
with self-supervised contrastive learning is proposed for differentiation of
positive links and negative links while content and behavior of nodes can be
captured simultaneously. We evaluate the proposed algorithm PSG on two link
