🎉MultiTQ

This is the code for the paper Multi-granularity Temporal Question Answering over Knowledge Graphs (Chen et al., ACL 2023).

MULTITQ is a large-scale dataset featuring ample relevant facts and multiple temporal granularities.

Architecture of MultiQA

Dataset and pretrained models

MultiTQ dataset can be found in ./data folder.

git clone https://github.com/czy1999/MultiTQ.git

cd ./MultiTQ/data
unzip Dataset.zip

cd ../MultiQA/models
unzip Models.zip

Running the code

MultiQA, a strong baseline to handle multi-granularity TKGQA

cd MultiQA 
python ner_task.py
python ./train_qa_model.py --model multiqa

Please explore more argument options in train_qa_model.py.

The implementation is based on TempoQR in TempoQR: Temporal Question Reasoning over Knowledge Graphs and their code from https://github.com/cmavro/TempoQR. You can find more installation details there. We use TComplEx KG Embeddings as implemented in https://github.com/facebookresearch/tkbc.
