# GRECO: Gammaticality-scorer for re-ranking corrections
GRECO is a quality estimation model for grammatical error correction. The model is trained to detect which words are incorrect and whether a word or phrase needs to be inserted after certain words. You can then use the model to get the grammaticality score of a sentence.

Please check the [official repository](https://github.com/nusnlp/greco/tree/main) for more implementation details and updates.

The model was published in the following paper:
> System Combination via Quality Estimation for Grammatical Error Correction ([PDF](https://arxiv.org/abs/2310.14947) | [ACL Anthology](https://aclanthology.org/2023.emnlp-main.785/)) <br>
> [Muhammad Reza Qorib](https://mrqorib.github.io/) and [Hwee Tou Ng](https://www.comp.nus.edu.sg/~nght/) <br>
> The 2023 Conference on Empirical Methods in Natural Language Processing (EMNLP)
