Pretraining Language Models with Text-Attributed Heterogeneous Graphs

Data Preparation

Please download the datasets from DatasetsForTHLM , and put it into ./Data

Model Pretraining

Example of training THLM on Patents dataset:

python main.py --dataset_name Patents

Get node embeddings

Obtain node embeddings for Patents, GoodReads and OAG_Venue in ./Downstream/preprocess_data

Example of obtaining node embeddings for Patents:

python Patent_features.py

Model Evaluation

• Link Prediction for OAG_Venue: ./Downstream/Link-Train-OAG

• Link Prediction for Patents/GoodReads: ./Downstream/Link-Train-Patent

• Node Classification for OAG_Venue: ./Downstream/train-OAG

• Node Classification for Patents/GoodReads: ./Downstream/train-Patent

Pre-trained Language Models

We also provide the pre-trained language models on these three datasets at HuggingFace.

Environments:

• PyTorch 2.0.0
• transformers 4.23.1
• dgl 0.9.1
• tqdm
• numpy
