Requirements

Our code works with the following environment.

• python=3.7
• pytorch=1.3

Dataset

To obtain the data, you can go to data directory for details.

Downloading BERT and ASA-WD

In our paper, we use BERT (paper) as the encoder.

For BERT, please download pre-trained BERT-Base and BERT-Large English from Google or from HuggingFace. If you download it from Google, you need to convert the model from TensorFlow version to PyTorch version.

For ASA-WD, you can download the models we trained in our experiments from Google Drive or Baidu Net Disk (passwword: ga1w).

Run on Sample Data

Run run_sample.sh to train a model on the small sample data under the sample_data directory.

Training and Testing

You can find the command lines to train and test models in run_train.sh and run_test.sh, respectively.

Here are some important parameters:

• --do_train: train the model.
• --do_eval: test the model.

To-do List

• Release the code to get the data.
• Regular maintenance.

You can leave comments in the Issues section, if you want us to implement any functions.
