PORORO: Platform Of neuRal mOdels for natuRal language prOcessing

pororo performs Natural Language Processing and Speech-related tasks.

It is easy to solve various subtasks in the natural language and speech processing field by simply passing the task name.


  • pororo is based on torch=1.6(cuda 10.1) and python>=3.6

  • You can install a package through the command below:

pip install pororo
  • Or you can install it locally:
git clone https://github.com/kakaobrain/pororo.git
cd pororo
pip install -e .
  • For library installation for specific tasks other than the common modules, please refer to INSTALL.md

  • For the utilization of Automatic Speech Recognition, wav2letter should be installed separately. For the installation, please run the asr-install.sh

bash asr-install.sh
  • For the utilization of Speech Synthesis, please run the tts-install.sh
bash tts-install.sh


  • pororo can be used as follows:
  • First, in order to import pororo, you must execute the following snippet
>>> from pororo import Pororo
  • After the import, you can check the tasks currently supported by the pororo through the following commands
>>> from pororo import Pororo
>>> Pororo.available_tasks()
"Available tasks are ['mrc', 'rc', 'qa', 'question_answering', 'machine_reading_comprehension', 'reading_comprehension', 'sentiment', 'sentiment_analysis', 'nli', 'natural_language_inference', 'inference', 'fill', 'fill_in_blank', 'fib', 'para', 'pi', 'cse', 'contextual_subword_embedding', 'similarity', 'sts', 'semantic_textual_similarity', 'sentence_similarity', 'sentvec', 'sentence_embedding', 'sentence_vector', 'se', 'inflection', 'morphological_inflection', 'g2p', 'grapheme_to_phoneme', 'grapheme_to_phoneme_conversion', 'w2v', 'wordvec', 'word2vec', 'word_vector', 'word_embedding', 'tokenize', 'tokenise', 'tokenization', 'tokenisation', 'tok', 'segmentation', 'seg', 'mt', 'machine_translation', 'translation', 'pos', 'tag', 'pos_tagging', 'tagging', 'const', 'constituency', 'constituency_parsing', 'cp', 'pg', 'collocation', 'collocate', 'col', 'word_translation', 'wt', 'summarization', 'summarisation', 'text_summarization', 'text_summarisation', 'summary', 'gec', 'review', 'review_scoring', 'lemmatization', 'lemmatisation', 'lemma', 'ner', 'named_entity_recognition', 'entity_recognition', 'zero-topic', 'dp', 'dep_parse', 'caption', 'captioning', 'asr', 'speech_recognition', 'st', 'speech_translation', 'ocr', 'srl', 'semantic_role_labeling', 'p2g', 'aes', 'essay', 'qg', 'question_generation', 'age_suitability']"
  • To check which models are supported by each task, you can go through the following process
>>> from pororo import Pororo
>>> Pororo.available_models("collocation")
'Available models for collocation are ([lang]: ko, [model]: kollocate), ([lang]: en, [model]: collocate.en), ([lang]: ja, [model]: collocate.ja), ([lang]: zh, [model]: collocate.zh)'
  • If you want to perform a specific task, you can put the task name in the task argument and the language name in the lang argument
>>> from pororo import Pororo
>>> ner = Pororo(task="ner", lang="en")
  • After object construction, it can be used in a way that passes the input value as follows:
>>> ner("Michael Jeffrey Jordan (born February 17, 1963) is an American businessman and former professional basketball player.")
[('Michael Jeffrey Jordan', 'PERSON'), ('(', 'O'), ('born', 'O'), ('February 17, 1963)', 'DATE'), ('is', 'O'), ('an', 'O'), ('American', 'NORP'), ('businessman', 'O'), ('and', 'O'), ('former', 'O'), ('professional', 'O'), ('basketball', 'O'), ('player', 'O'), ('.', 'O')]
  • If task supports multiple languages, you can change the lang argument to take advantage of models trained in different languages.
>>> ner = Pororo(task="ner", lang="ko")
>>> ner("마이클 제프리 조던(영어: Michael Jeffrey Jordan, 1963년 2월 17일 ~ )은 미국의 은퇴한 농구 선수이다.")
[('마이클 제프리 조던', 'PERSON'), ('(', 'O'), ('영어', 'CIVILIZATION'), (':', 'O'), (' ', 'O'), ('Michael Jeffrey Jordan', 'PERSON'), (',', 'O'), (' ', 'O'), ('1963년 2월 17일 ~', 'DATE'), (' ', 'O'), (')은', 'O'), (' ', 'O'), ('미국', 'LOCATION'), ('의', 'O'), (' ', 'O'), ('은퇴한', 'O'), (' ', 'O'), ('농구 선수', 'CIVILIZATION'), ('이다.', 'O')]
>>> ner = Pororo(task="ner", lang="ja")
>>> ner("マイケル・ジェフリー・ジョーダンは、アメリカ合衆国の元バスケットボール選手")
[('マイケル・ジェフリー・ジョーダン', 'PERSON'), ('は', 'O'), ('、アメリカ合衆国', 'O'), ('の', 'O'), ('元', 'O'), ('バスケットボール', 'O'), ('選手', 'O')]
>>> ner = Pororo(task="ner", lang="zh")
>>> ner("麥可·傑佛瑞·喬丹是美國退役NBA職業籃球運動員,也是一名商人,現任夏洛特黃蜂董事長及主要股東")
[('麥可·傑佛瑞·喬丹', 'PERSON'), ('是', 'O'), ('美國', 'GPE'), ('退', 'O'), ('役', 'O'), ('nba', 'ORG'), ('職', 'O'), ('業', 'O'), ('籃', 'O'), ('球', 'O'), ('運', 'O'), ('動', 'O'), ('員', 'O'), (',', 'O'), ('也', 'O'), ('是', 'O'), ('一', 'O'), ('名', 'O'), ('商', 'O'), ('人', 'O'), (',', 'O'), ('現', 'O'), ('任', 'O'), ('夏洛特黃蜂', 'ORG'), ('董', 'O'), ('事', 'O'), ('長', 'O'), ('及', 'O'), ('主', 'O'), ('要', 'O'), ('股', 'O'), ('東', 'O')]
  • If the task supports multiple models, you can change the model argument to use another model.
>>> from pororo import Pororo
>>> mt = Pororo(task="mt", lang="multi", model="transformer.large.multi.mtpg")
>>> fast_mt = Pororo(task="mt", lang="multi", model="transformer.large.multi.fast.mtpg")
