BLEU score introduction.

BLEU (%) score	Interpretation of translation quality
<10	No real effect
10∼19	Difficulty understanding key points
20∼29	Key points clear, but with prominent syntax errors
30∼40	Between understandable and good quality translations
40∼50	Higher quality translation
50∼60	High quality, fluent, and easy to understand
>60	Equivalent to high-quality human translation
