Model Description

OpenNMT model for English-Galician using a transformer architecture.

How to translate

onmt_translate -src input_text -model NOS-MT-gl-es.pt -output ./output_file.txt -replace_unk -gpu 0
  • The result of the translation will be in the PATH indicated by the -output flag.

Training

In the training we have used authentic and synthetic corpora from ProxectoN贸s. The former are corpora of translations directly produced by human translators. The latter are corpora of English-Portuguese translations, which we have converted into English-Galician by means of Portuguese-Galician translation with Opentrad/Apertium and transliteration for out-of-vocabulary words.

Training process

  • Tokenization of the datasets made with linguakit tokeniser https://github.com/citiususc/Linguakit
  • The vocabulary for the models was generated through the script learn_bpe.py of OpenNMT
  • Using .yaml in this repository you can replicate the training process as follows
onmt_build_vocab -config  bpe-gl-es_emb.yaml -n_sample 100000
onmt_train -config bpe-gl-es_emb.yaml

Hyper-parameters

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

Evaluation

The BLEU evaluation of the models is made with a mixture of internally developed tests (gold1, gold2, test-suite) and other datasets available in Galician (Flores).
