Setup

To install requirements

pip install -r requirements.txt

Data

Download: https://drive.google.com/drive/folders/1heVF8flYGfrxEnBqNvjYcgTzpSBke6IV?usp=share_link

Put data folder under the outputs directory. e.g., ZETT/outputs/data/fewrel/unseen_10_seed_0/train.jsonl

Train

For each dataset, we have 30 different setups for 5/10/15 unseen relations and 5 different data folds. To train with a specific setting:

e.g. on FewRel dataset with the setting of 10 unseen relations and data fold #0:

python run_zett.py train --data_name ['fewrel'] --n_unseen_rel [10] --rd_fold [0] --model_name {model_name}

e.g. on wiki-ZSL dataset with the setting of 15 unseen relations and data fold #1, 2, 3:

python run_zett.py train --data_name ['wiki'] --n_unseen_rel [15] --rd_fold [1, 2, 3] --model_name {model_name}

To train for all settings at once:

python run_zett.py train --model_name {model_name}

Evaluate triplet extraction

Test on the single-triplet test set

To test with a specific setting:

e.g. on FewRel dataset with the setting of 10 unseen relations and data fold #0:

python run_zett.py test --data_name ['fewrel'] --n_unseen_rel [10] --rd_fold [0] --model_name {model_name}

Test all setting:

python run_zett.py test --model_name {model_name}

Test on the multi-triplet test set

Set eval_mode option to multi

python run_zett.py test --model_name {model_name} --eval_mode 'multi'

Inference without relation constraint

Set use_label_constraint option to False

python run_zett.py test --model_name {model_name} --use_label_constraint False

Evaluate relation extraction (or relation classification)

Use task_type option to set the target task.

python run_zett.py test --model_name {model_name} --task_type RC

Choice of templates

Train/test with the paraphrased templates from the back-translation (English-German) machine translation model.

python run_zett.py train --model_name {model_name} --templ_file templates/templates_paraphrased_top1.tsv

python run_zett.py test --model_name {model_name} --templ_file templates/templates_paraphrased_top1.tsv
