[“**Heterogeneous Graph Transformer**”](https://arxiv.org/abs/2003.01332) is a graph neural network architecture that can deal with large-scale heterogeneous and dynamic graphs.

This toy experiment is based on DGL's official [tutorial](https://docs.dgl.ai/en/0.4.x/generated/dgl.heterograph.html). As the ACM datasets doesn't have input feature, we simply randomly assign features for each node. Such process can be simply replaced by any prepared features.
