Does POP work in my language?

Probably yes. The source article states that POP currently works with 61 languages.

Google's NLP API supports a smaller set of languages. The article lists:

  • English
  • Spanish
  • Japanese
  • Chinese, simplified and traditional
  • French
  • German
  • Italian
  • Korean
  • Portuguese
  • Russian

The source notes that POP optimization can still be used even when the target language is not supported by Google's NLP API.
