BLEU in BuildAnalytics

What is a good BLEU Score? 

BLEU scores range from 0-100%. A score less than 15% means that your KantanMT engine is not performing optimally and that a high level of post-editing will be required to finalise your translations and reach publishable quality.

A score greater than 50% is a very good score; significantly less post-editing will be required to achieve publishable translation quality.

 

Improving BLEU Score

There is a high correlation between the number of words used in training a KantanMT engine and its BLEU score. The more training data is uploaded to KantanMT, the better the BLEU score and consequently, the generated translations.
