Overview

This is the code for ACL2021 paper A Unified Generative Framework for Aspect-Based Sentiment Analysis

Install the package in the requirements.txt, then use the following commands to install two other packages

pip install git+https://github.com/fastnlp/[email protected]
pip install git+https://github.com/fastnlp/fitlog

The structure of this code is as follows

 -  data
    - fan  # D_19 in paper
    - penga  # D_20a in paper
    - pengb  # D_20b in paper
    - wang  # D_17 in paper
- fan/
    train_fan.py  # training file for fan data
- peng/
    train.py  # training file for penga and pengb
- wang/
    train_wang.py  # training file for wang

Please do remember to cite these dataset paper if you use them.

After enter the folder, you can run the code by directly using

python train.py --dataset pengb/14lap

The following output should be achieved

Save cache to caches/data_facebook/bart-base_pengb/14lap_False.pt.
