Recent versions of the following packages for Python 3 are required:

• PyTorch 1.2.0
• DGL 0.3.1
• NetworkX 2.3
• scikit-learn 0.21.3
• NumPy 1.17.2
• SciPy 1.3.1

Dependencies for the preprocessing code are not listed here.

The preprocessed datasets are available at:

• IMDb - Dropbox
• DBLP - Dropbox
• Last.fm - Dropbox

The GloVe word vectors are obtained from GloVe. Here is the direct link for the version we used in DBLP preprocessing.

1. Create checkpoint/ and data/preprocessed directories
2. Extract the zip file downloaded from the section above to data/preprocessed
   • E.g., extract the content of IMDB_processed.zip to data/preprocessed/IMDB_processed
3. Execute one of the following three commands from the project home directory:
   • python run_IMDB.py
   • python run_DBLP.py
   • python run_LastFM.py

For more information about the available options of the model, you may check by executing python run_IMDB.py --help
