Installation

• Run pip install -r requirements.txt
• Run python setup.py install
• Note that the code requires an older version of hugging face transformers.

Datasets

• The CQ datasets along with the filters for filtered setting can be found in ./scripts/data/

Hardware Requirements

• Linux with at least 2 GPUs each with 11GB or 1 GPU > 20G B, set CUDA_VISIBLE_DEVICES appropriately.

Running BiQE

1. run train.sh for training a model
2. run test.sh for evaluation

Hyperparameters and Dataset details

• Set hyperparameters and dataset directories in train.sh and test.sh
• For wn18rr simply change the directory name from fb15k-237 to wn18rr in train.sh/test.sh
