# NUS Grammatical Error Correction 2017 (SMT-based)
----------------------------------------------------------------------------

This repository contains scripts and models to replicate the results of the state-of-the-art (in 2017) grammatical error correction (GEC) system. The system primarily uses the statistical machine translation (SMT) framework, with neural and character level translation components.

If you use the models from this work, please cite this [paper](http://aclweb.org/anthology/W17-5037):

### Prerequistes

1. cmph - For compact phrase tables
2. nplm - For neural network joint model feature in Moses.
3. Moses Release 3.0
    - Execute `./download.sh` in `software/` directory to download the specific revision of Moses used in this work.
    - Moses needs to be compiled with `---with-cmph=/path/to/cmph-2.0 --with-nplm=/path/to/nplm --max-kenlm-order=9` this flag
