This repository contains a TensorFlow implementation of Relational Graph Convolutional Networks (R-GCN), as well as experiments on relational link prediction. The description of the model and the results can be found in our paper:

Modeling Relational Data with Graph Convolutional Networks. Michael Schlichtkrull, Thomas N. Kipf, Peter Bloem, Rianne van den Berg, Ivan Titov, Max Welling (ArXiv 2017)

Requirements

• TensorFlow (1.4)

Running demo

We provide a bash script to run a demo of our code. In the folder settings, a collection of configuration files can be found. The block diagonal model used in our paper is represented through the configuration file settings/gcn_block.exp. To run a given experiment, execute our bash script as follows:

bash run-train.sh \[configuration\]

We advise that training can take up to several hours and require a significant amount of memory.
