PyTorch code for the IEEE Access paper: Tree-KGQA: An Unsupervised Approach for Question Answering Over Knowledge Graphs [PDF].

Required : Anaconda

conda create -n treekgqa -y python=3.8 && source activate treekgqa
pip install -r requirements.txt
chmod +x setup.sh
./setup.sh

Note: the code require more cleaning.

We use Wikidata entities provided by ELQ . In order to perform inference, first index the Wikidata entities by executing the follwing command:

python utils/indexer.py --output_path data/wikidata/indexed_wikidata_entities.pkl --faiss_index hnsw --save_index

Indexing might take few hours depending on the system capabilities and resource.

To test entity linking on the webqsp dataset run the following command:

python -u run_kgqa.py --dataset webqsp --task EL --use_api --use_indexing --QAtype complex --evaluate
