Our code is written with python 2.7.

Our code requires PyTorch version >= 0.4.1. Please follow the instructions here: https://github.com/pytorch/pytorch#installation.

You will need to first process the data using data_preprocess.py and then run our model through main.py.

Please first call the data_processing.py and make sure the processed dataframe has the following columns: ['comp_tokens', 'simp_tokens','comp_ids','simp_ids', 'comp_pos_tags', 'comp_pos_ids', edit_labels','new_edit_ids']

This can be done by the following steps:

1.process_raw_data(comp_txt, simp_txt)

2.editnet_data_to_editnetID(df,output_path).

after getting the processed data (in a dataframe), you can run the training through main.py. In the paper, we filtered out the rows where the source sentence and the target sentence are identical to encourge editing, you can do this by adding a line at line 41 in data_processing.py:

comp_txt,simp_txt=unzip([(i[0],i[1]) for i in zip(comp_txt,simp_txt)] if i[0] != i[1]]).
