• pytorch=1.7.1
• python=3.7

Download the pretrained RoBERTa model (link, password:2fv2) and unzip it into the folder pretrained.

The MAMS data is preprocessed by the script preprocess.py. The original and preprocessed versions of the data are provided in the folder data.

Run the command python main_ATSA.py to train and test the ATSA model.

You can change training settings in the file configs.py.

Run the command python main_ACSA.py to train and test the ACSA model.

You can change training settings in the file configs.py.
