Warning: The Tatoeba Corpus is not error-free.

  • Due to the nature of a public collaborative project, this data will never be 100% free of errors.
  • Be aware of the following.
    • Though we recommend native-speaker contributions, a number of non-native speakers have contributed in languages they are learning.
    • We ask our members not to change archaic language to something that currently sounds natural.
  • Translations may not always be accurate, even though the linked sentences are correct sentences.

Suggestions for Those Planning to Use the Corpus

  • Don't use the whole corpus, but do some filtering out of obviously suspect items. (Things like items tagged @need native check, @change, archaic, non-sentence, etc. Browse Tags to find others.)
  • You may want to eliminate all sentences not "owned" by native speakers. However, even this will not guarantee perfect data. (See Native Speakers maintained by CK)
  • You should inform your audience that the data may contain errors (See an example) and explain what steps you have taken to help minimize the errors.
  • Since corrections are being made all the time, you should frequently update your project so your audience benefits from these corrections.
  • You might want to only use sentences you have personally proofread if you are creating materials for people studying a foreign language. This helps make sure that what you are teaching people isn't a mistake. *(See a live example on the right side of this page::
