**Descrición do Modelo / Model description** 

Modelo feito con OpenNMT para o par español-galego utilizando unha arquitectura transformer.

Model developed with OpenNMT for the Spanish-Galician pair using a transformer architecture.

**Como traducir / How to translate**

+ Abrir terminal bash / Open bash terminal
+ Instalar / Installing [Python 3.9](https://www.python.org/downloads/release/python-390/) 
+ Instalar / Installing [Open NMT toolkit v.2.2](https://github.com/OpenNMT/OpenNMT-py)
+ Traducir un input_text utilizando o modelo NOS-MT-es-gl co seguinte comando / Translating an input_text using the NOS-MT-en-gl model with the following command:

```bash 
onmt_translate -src input_text -model NOS-MT-es-gl -output ./output_file.txt -replace_unk -phrase_table phrase_table-es-gl.txt -gpu 0
```
+ O resultado da tradución estará no PATH indicado no flag -output / The result of the translation will be in the PATH indicated by the -output flag.

**Adestramento / Training**

No adestramento, utilizamos corpora auténticos e sintéticos. Os primeiros son corpora de traducións feitas directamente por tradutores humanos. Os segundos son corpora de traducións español-portugués, que convertemos en español-galego a través da tradución automática portugués-galego con Opentrad/Apertium e transliteración para palabras fóra de vocabulário.

In the training we have used authentic and synthetic corpora. The former are corpora of translations directly produced by human translators. The latter are corpora of spanish-portuguese translations, which we have converted into spanish-galician by means of portuguese-galician translation with Opentrad/Apertium and transliteration for out-of-vocabulary words. 


**Procedemento de adestramento / Training process**

+ Tokenization dos datasets feita co tokenizador de linguakit / Tokenization of the datasets made with linguakit tokeniser https://github.com/citiususc/Linguakit

+ O vocabulario para os modelos foi xerado a través do script / Vocabulary for the models was created by the script [learn_bpe.py](https://github.com/OpenNMT/OpenNMT-py/blob/master/tools/learn_bpe.py) da open NMT

+ Usando o .yaml neste repositorio pode replicar o proceso de adestramento do seguinte xeito / Using the .yaml in this repository you can replicate the training process as follows

```bash 
onmt_build_vocab -config  bpe-es-gl_emb.yaml -n_sample 100000
onmt_train -config bpe-es-gl_emb.yaml
```

**Hiperparámetros / Hyper-parameters** 

Os parámetros usados para o desenvolvimento do modelo poden ser consultados directamente no mesmo ficheiro .yaml  bpe-es-gl_emb.yaml 

The parameters used for the development of the model can be directly viewed in the same .yaml file bpe-es-gl_emb.yaml 

**Avaliación / Evaluation**

A avaliación BLEU dos modelos é feita cunha mistura de tests desenvolvidos internamente (gold1, gold2, test-suite) con outros datasets disponíbeis en galego (Flores).

The BLEU evaluation of the models is done by mixing internally developed tests (gold1, gold2, test-suite) with other datasets available in Galician (Flores).

| GOLD 1        | GOLD 2        | FLORES  | TEST-SUITE|
| ------------- |:-------------:| -------:|----------:| 
| 79.6          | 43.3          | 21.8    | 74.3      |
