BLEU

Ever wondered how computers know if a translation makes sense?

Imagine you're using a translation app to understand a foreign movie's subtitles. You want to make sure the subtitles are accurate and readable.

Think of BLEU as a scorecard that compares the app's translation to a set of professional translations, giving you a sense of how good it is.

Example

If the app's translation closely matches the professional ones, it gets a high BLEU score, indicating better quality.

Remember this

BLEU score helps you quickly gauge the accuracy of machine translations.
