This repo contains the implementation of our paper.

The original code was cloned from from this repo, which is a PyTorch implementation for paper Position-aware Attention and Supervised Data Improve Slot Filling.

The TACRED dataset: Details on the TAC Relation Extraction Dataset can be found on this dataset website.

• Python 3 (tested on 3.6.2)
• PyTorch (tested on 1.0.0)
• tqdm, bert_as_service, maybe a couple others
• unzip, wget (for downloading only)

First, download and unzip GloVe vectors from the Stanford website, with:

chmod +x download.sh; ./download.sh

Then tokenize data to run with BERT or SciBERT with:

python data/data_tok.py

Train using the commands in cmdcheat.txt. You need two terminal windows open, or two separate tmux sessions. Run the corresponding bert-as-service command and then run the python train.py command, both with the appropriate flags listed in cmdcheat.txt.

Model checkpoints and logs will be saved to ./saved_models/00.

Run evaluation on the test set with:

python eval.py saved_models/00 --dataset test

This will use the best_model.pt by default. Use --model checkpoint_epoch_10.pt to specify a model checkpoint file. Add --out saved_models/out/test1.pkl to write model probability output to files (for ensemble, etc.).

You will need bert-as-service running for the test phase as well.

Please see the example script ensemble.sh.
