Resources and code for paper "Fuzzy Logic based Logical Query Answering on Knowledge Graphs".

Environment

Make sure your local environment has the following installed:

Python3.9
torch == 1.9.0
wandb == 0.9.7

Install the dependency using:

pip install -r requirements.txt

Download data

Download data from here and put it under data folder.

The directory structure should be like [PROJECT_DIR]/data/NELL-betae/train-queries.pkl.

Only FB15k-237 and NELL995 are used in our study.

Train

Training script example: ./run.sh

It usually takes 4 days to a week to finish a run on a NVIDIA® GP102 TITAN Xp (12GB) GPU.

TODO: More training scripts for easy training will be added soon.

Test

The trained model will be automatically stored under the folder ./trained_models. The model name will be [WANDB_RUN_NAME].pt.

To test a trained model, you can use the following command:

python ./test-pretrained-model.py [DATA_NAME] [WANDB_RUN_NAME]

By default, the test tests for product logic. You can also test for other logic systems ('godel' or 'luka') by modifying the logic variable in the script.

Test the pretrained model

The pretrained FuzzQE model (product logic) for NELL can be downloaded here. You can put it under ./trained_models and use the following command to test it:

python ./test-pretrained-model.py NELL feasible-resonance-1518

TODO: More pretrained models will be uploaded soon.
