Released code for our EMNLP22 paper: UniRel: Unified Representation and Interaction for Joint Relational Triple Extraction.

Join the Discord if there are any questions.

Updates

  • 2023-06-01
    • Add multi-token entity implementation.
    • Provide UniRel class in predict.py for easy inference and a checkpoint trained on nyt (multi-token) for trying.

Usage

Prerequisites

UniRel is implemented with Python == 3.8 and pytorch == 1.7.1, Other main requirments are:

  • tdqm
  • transformers == 4.12.5
  • wandb

The detail requirments could be found at requirements.txt

Data

We obtain the data from TPLinker, please kindly refer to TPLinker officail repository. Change two filename of the download data:

  • train_data.json -> train_split.json
  • test_triples.json -> test_data.json

You can also download the data from here

Pretrained Model

We use the bert-base-cased model from Huggingface, you can download it by following their instrcution or let Transformers to automatically download. After that, place the files at the root directory of the project (./bert-base-cased).

I provided a checkpoint for trying predict. You can download here.

Train & Evalutaion

All parameter are listed in the script run_nyt.sh and run_webnlg.sh. By run with command bash run_nyt.sh can do train and evaluation.
