Link prediction with GraphSAGE¶. In this example, we use our implementation of the GraphSAGE algorithm to build a model that predicts citation links in the Cora dataset (see below). The problem is treated as a supervised link prediction problem on a homogeneous citation network with nodes representing papers (with attributes such as binary keyword indicators and …

Aug 19, 2019 · Here is a repo about link prediction in github. NOTE THAT it is implemented on TensorFlow 1.7.0 and networkx 2.0 (the repo's owner shows that networkx 2.0+ does not work, in this issue) and its arxiv preprint paper: Link Prediction Based on Graph Neural Networks. I installed it and run it on the environment below:

PyG (PyTorch Geometric) is a library built upon PyTorch to easily write and train Graph Neural Networks (GNNs) for a wide range of applications related to structured data. It consists of various methods for deep learning on graphs and other irregular structures, also known as geometric deep learning, from a variety of published papers.

Prediction task: The task is to predict new triplet edges given the training edges. The evaluation metric follows the standard filtered metric widely used in KG. Specifically, we corrupt each test triplet edges by replacing its head or tail with randomly-sampled 1,000 negative entities (500 for head and 500 for tail ), while ensuring the resulting triplets do not appear in KG.

Prediction task: The task is to predict missing citations given existing citations. Specifically, for each source paper, two of its references are randomly dropped, and we would like the model to rank the missing two references higher than 1,000 negative reference candidates.
