KTN transfers knowledges from label-abundant node types to zero-labeled node types within a sing heterogeneous graph. More specifically, KTN transfers Heterogeneous Graph Neural Networks (HGNN) that are trained on a source node type to a target node type without using any target labels.

You can see our NeurIPS 2022 paper for more details.

Data/ directory contains all files to preprocess OAG-CS raw datasets and extract OAG-ML and OAG-CN subgraphs. Model/ directory contains how to train HGNN and KTN models on the preprocessed heterogeneous datasets.

This implementation is based on python==3.7. To run the code, you need the dependencies listed in requirement.txt

Our current experiments are conducted on Open Academic Graph on Computer Science field (OAG-CS). More information to how to download and preprocess OAG-CS dataset can be found in Data/ directory.

Execute cd MODEL; sh run_oag.sh to run 8 different zero-shot transfer learning tasks on the OAG-CS graph using KTN. The details of other optional hyperparameters can be found in args.py.

Please consider citing the following paper when using our code for your application.
