The model is a port of our CommentBERT model from the paper:
```
@inproceedings{ochodek2022automated,
title={Automated code review comment classification to improve modern code reviews},
author={Ochodek, Miroslaw and Staron, Miroslaw and Meding, Wilhelm and S{\"o}der, Ola},
booktitle={International Conference on Software Quality},
pages={23--40},
year={2022},
organization={Springer}
}
```
The original model was implemented in Keras with two outputs - comment-purpose and subject-purpose. Here, we divided it into two separate model with one output each.
