"Language" (Built-in Classifier)

Identify which natural language the text is in.



  • This classifier assumes the text input is written in a unique language. The probabilities reflect the belief in which language the text is written, not the proportion of languages.
  • For large texts, the classifier randomly selects snippets to determine the overall language.
  • In the current version, all texts must be written in one of their official alphabets.
