Requirements

• PyTorch
• Run pip install -r requirements.txt to install the required packages.

Dataset

The ATOMIC dataset used in this paper is available here and the ConceptNet graph is available here. For convenience, both the pre-processed version of ATOMIC and ConceptNet used in the experiments are provided at this link.

Note: The ATOMIC dataset was pre-processed to canonicalize person references and remove punctuations (described in preprocess_atomic.py.

Note: The original evaluation sets provided in the ConceptNet dataset contain correct as well as incorrect tuples for evaluating binary classification accuracy. valid.txt in data/conceptnet is the concatenation of the correct tuples from the two development sets provided in the original dataset while test.txt is the set of correct tuples from the original test set.

Training

To train a model, run the following command:

python -u src/run_kbc_subgraph.py --dataset conceptnet --evaluate-every 10 --n-layers 2 --graph-batch-size 60000 --sim_relations --bert_concat

This trains the model and saves the model under the saved_models directory.

Language Model Fine-tuning

In this work, we use representations from a BERT model fine-tuned to the language of the nodes in the knowledge graph.

The script to fine-tune BERT as a language model on the two knowledge graphs is present in the lm_finetuning/ directory. For example, here is a command to fine-tune BERT as a language model on ConceptNet:

python lm_finetuning/simple_lm_finetuning.py --train_corpus {CONCEPTNET_TRAIN_CORPUS} --bert_model bert-large-uncased --output_dir {OUTPUT_DIR}

Pre-Trained Models

We provide the fine-tuned BERT models and pre-computed BERT embeddings for both ConceptNet and ATOMIC at this link. If you unzip the downloaded file in the root directory of the repository, the training script will load the embeddings.

We also provide the pre-trained KB completion models for both datasets for ease of use. Link to Conceptnet model and ATOMIC model.

Evaluation

To evaluate a trained model, and get predictions, provide the model path to the --load_model argument and use the --eval_only argument. For example, to evaluate the pre-trained ConceptNet model provided above, use the following command:

CUDA_VISIBLE_DEVICES={GPU_ID} python src/run_kbc_subgraph.py --dataset conceptnet --sim_relations --bert_concat --use_bias --load_model {PATH_TO_PRETRAINED_MODEL} --eval_only --write_results

This will load the pre-trained model, and evaluate it on the validation and test set. The predictions are saved to ./topk_results.json.

Similarly, to evaluate the trained model on ATOMIC, use the following command:

CUDA_VISIBLE_DEVICES={GPU_ID} python src/run_kbc_subgraph.py --dataset atomic --sim_relations --use_bias --load_model {PATH_TO_PRETRAINED_MODEL} --eval_only --write_results
