This model is part of the [OPUS-MT project](https://github.com/Helsinki-NLP/Opus-MT), an effort to make neural machine translation models widely available and accessible for many languages in the world. All models are originally trained using the amazing framework of [Marian NMT](https://marian-nmt.github.io/), an efficient NMT implementation written in pure C++. The models have been converted to pyTorch using the transformers library by huggingface. Training data is taken from [OPUS](https://opus.nlpl.eu/) and training pipelines use the procedures of [OPUS-MT-train](https://github.com/Helsinki-NLP/Opus-MT-train). * Publications: [OPUS-MT – Building open translation services for the World](https://aclanthology.org/2020.eamt-1.61/) and [The Tatoeba Translation Challenge – Realistic Data Sets for Low Resource and Multilingual MT](https://aclanthology.org/2020.wmt-1.139/) (Please, cite if you use this model.) ``` @inproceedings{tiedemann-thottingal-2020-opus, title = "{OPUS}-{MT} {--} Building open translation services for the World", author = {Tiedemann, J{\"o}rg and Thottingal, Santhosh}, booktitle = "Proceedings of the 22nd Annual Conference of the European Association for Machine Translation", month = nov, year = "2020", address = "Lisboa, Portugal", publisher = "European Association for Machine Translation", url = "https://aclanthology.org/2020.eamt-1.61", pages = "479--480", } @inproceedings{tiedemann-2020-tatoeba, title = "The Tatoeba Translation Challenge {--} Realistic Data Sets for Low Resource and Multilingual {MT}", author = {Tiedemann, J{\"o}rg}, booktitle = "Proceedings of the Fifth Conference on Machine Translation", month = nov, year = "2020", address = "Online", publisher = "Association for Computational Linguistics", url = "https://aclanthology.org/2020.wmt-1.139", pages = "1174--1182", } ``` ## Model info * Release: 2022-03-17 * source language(s): ces dsb hsb pol * target language(s): eng * model: transformer-big * data: opusTCv20210807+bt ([source](https://github.com/Helsinki-NLP/Tatoeba-Challenge)) * tokenization: SentencePiece (spm32k,spm32k) * original model: [opusTCv20210807+bt_transformer-big_2022-03-17.zip](https://object.pouta.csc.fi/Tatoeba-MT-models/zlw-eng/opusTCv20210807+bt_transformer-big_2022-03-17.zip) * more information released models: [OPUS-MT zlw-eng README](https://github.com/Helsinki-NLP/Tatoeba-Challenge/tree/master/models/zlw-eng/README.md) ## Usage A short example code: ```python from transformers import MarianMTModel, MarianTokenizer src_text = [ "Aoi'ego hobby to tańczenie.", "Myślisz, że Tom planuje to zrobić?" ] model_name = "pytorch-models/opus-mt-tc-big-zlw-en" tokenizer = MarianTokenizer.from_pretrained(model_name) model = MarianMTModel.from_pretrained(model_name) translated = model.generate(**tokenizer(src_text, return_tensors="pt", padding=True)) for t in translated: print( tokenizer.decode(t, skip_special_tokens=True) ) # expected output: # Aoi's hobby is dancing. # You think Tom's planning on doing that? ``` You can also use OPUS-MT models with the transformers pipelines, for example: ```python from transformers import pipeline pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-zlw-en") print(pipe("Aoi'ego hobby to tańczenie.")) # expected output: Aoi's hobby is dancing. ``` ## Benchmarks * test set translations: [opusTCv20210807+bt_transformer-big_2022-03-17.test.txt](https://object.pouta.csc.fi/Tatoeba-MT-models/zlw-eng/opusTCv20210807+bt_transformer-big_2022-03-17.test.txt) * test set scores: [opusTCv20210807+bt_transformer-big_2022-03-17.eval.txt](https://object.pouta.csc.fi/Tatoeba-MT-models/zlw-eng/opusTCv20210807+bt_transformer-big_2022-03-17.eval.txt) * benchmark results: [benchmark_results.txt](benchmark_results.txt) * benchmark output: [benchmark_translations.zip](benchmark_translations.zip) | langpair | testset | chr-F | BLEU | #sent | #words | |----------|---------|-------|-------|-------|--------| | ces-eng | tatoeba-test-v2021-08-07 | 0.71861 | 57.4 | 13824 | 105010 | | pol-eng | tatoeba-test-v2021-08-07 | 0.70544 | 55.7 | 10099 | 75766 | | ces-eng | flores101-devtest | 0.66444 | 41.2 | 1012 | 24721 | | pol-eng | flores101-devtest | 0.58301 | 29.6 | 1012 | 24721 | | slk-eng | flores101-devtest | 0.66103 | 40.0 | 1012 | 24721 | | ces-eng | multi30k_test_2016_flickr | 0.61482 | 37.6 | 1000 | 12955 | | ces-eng | multi30k_test_2018_flickr | 0.61405 | 37.4 | 1071 | 14689 | | pol-eng | newsdev2020 | 0.60478 | 32.7 | 2000 | 46654 | | ces-eng | newssyscomb2009 | 0.56495 | 30.2 | 502 | 11818 | | ces-eng | news-test2008 | 0.54300 | 26.3 | 2051 | 49380 | | ces-eng | newstest2009 | 0.56309 | 29.5 | 2525 | 65399 | | ces-eng | newstest2010 | 0.57778 | 30.7 | 2489 | 61711 | | ces-eng | newstest2011 | 0.57336 | 30.9 | 3003 | 74681 | | ces-eng | newstest2012 | 0.56761 | 29.4 | 3003 | 72812 | | ces-eng | newstest2013 | 0.58809 | 32.8 | 3000 | 64505 | | ces-eng | newstest2014 | 0.64401 | 38.7 | 3003 | 68065 | | ces-eng | newstest2015 | 0.58607 | 33.4 | 2656 | 53569 | | ces-eng | newstest2016 | 0.61780 | 37.1 | 2999 | 64670 | | ces-eng | newstest2017 | 0.58259 | 32.5 | 3005 | 61721 | | ces-eng | newstest2018 | 0.58677 | 33.1 | 2983 | 63495 | | pol-eng | newstest2020 | 0.60047 | 32.6 | 1001 | 21755 | ## Acknowledgements The work is supported by the [European Language Grid](https://www.european-language-grid.eu/) as [pilot project 2866](https://live.european-language-grid.eu/catalogue/#/resource/projects/2866), by the [FoTran project](https://www.helsinki.fi/en/researchgroups/natural-language-understanding-with-cross-lingual-grounding), funded by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 771113), and the [MeMAD project](https://memad.eu/), funded by the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement No 780069.
