**Model description**
Model developed with OpenNMT for the Spanish-Galician pair using the transformer architecture.
**How to translate**
+ Open bash terminal
+ Install [Python 3.9](https://www.python.org/downloads/release/python-390/)
+ Install [Open NMT toolkit v.2.2](https://github.com/OpenNMT/OpenNMT-py)
+ Translate an input_text using the NOS-MT-en-gl model with the following command:
```bash
onmt_translate -src input_text聽-model NOS-MT-es-gl -output ./output_file.txt -replace_unk -phrase_table phrase_table-es-gl.txt -gpu 0
```
+ The resulting translation will be in the PATH indicated by the -output flag.
**Training**
To train this model, we have used authentic and synthetic corpora from [ProxectoN贸s](https://github.com/proxectonos/corpora).
Authentic corpora are corpora produced by human translators. Synthetic corpora are Spanish-Portuguese translations, which have been converted to Spanish-Galician by means of Portuguese-Galician translation with Opentrad/Apertium and transliteration for out-of-vocabulary words.
**Training process**
+ Tokenisation was performed with a modified version of the [linguakit](https://github.com/citiususc/Linguakit) tokeniser (tokenizer.pl) that does not append a new line after each token.
+ All BPE models were generated with the script [learn_bpe.py](https://github.com/OpenNMT/OpenNMT-py/blob/master/tools/learn_bpe.py)
+ Using the .yaml in this repository it is possible to replicate the original training process. Before training the model, please verify that the path to each target (tgt) and (src) file is correct. Once this is done, proceed as follows:
```bash
onmt_build_vocab -config bpe-es-gl_emb.yaml -n_sample 100000
onmt_train -config bpe-es-gl_emb.yaml
```
**Hyper-parameters**
The parameters used for the development of the model can be directly viewed in the same .yaml file bpe-es-gl_emb.yaml
**Evaluation**
The BLEU evaluation of the models is done by mixing internally developed tests (gold1, gold2, test-suite) and other datasets available in Galician (Flores).
