Code for the ACL 2019 paper:

Improving Question Answering over Incomplete KBs with Knowledge-Aware Reader

Paper link: https://arxiv.org/abs/1905.07098

Model Overview:

Requirements

• PyTorch 1.0.1
• tensorboardX
• tqdm
• gluonnlp

Prepare data

mkdir datasets && cd datasets && wget https://sites.cs.ucsb.edu/~xwhan/datasets/webqsp.tar.gz && tar -xzvf webqsp.tar.gz && cd ..

Full KB setting

CUDA_VISIBLE_DEVICES=0 python train.py --model_id KAReader_full_kb --max_num_neighbors 50 --label_smooth 0.1 --data_folder datasets/webqsp/full/ 

Incomplete KB setting

Note: The Hits@1 should match or be slightly better than the number reported in the paper. More tuning on threshold should give you better F1 score.
