Source codes and data for COLING 2022 Paper "Noise-injected Consistency Training and Entropy-constrained Pseudo Labeling for Semi-supervised Extractive Summarization"
You may first download complete dataset in Google Drive (URLs are in the table below) or Baidu Netdisk, and then overwrite the empty jsonl files in the "Data" folder.
| supervised train data | unsupervised train data | validation | test | |
|---|---|---|---|---|
| cnndm | train.jsonl | unsupervised_data.jsonl | val.jsonl | test.jsonl |
| xsum | train.jsonl | unsupervised_data.jsonl | val.jsonl | test.jsonl |
You can manually select a specific amount of labeled data(10/100/1000) according to your needs (recommended), or without any pre-processing, the program will automatically select data at the top of data files.
Our unsupervised data are all from supervised datasets, but with label masking and data augmentation. You can use our processed data, or refer to tinybert to augment the data yourself.
The core program is train.py. You can run the script in the "script" folder.
Take srcipt/cnndm.sh as an example:
