Score interpretation

[kasrahabib]

Hi,

I took a look over the paper and a couple of other places.
I did not understand what is the score number representing.
Is it percentage or just a score (number) from 0 to 100, where 100 is the closest matching one?

E.g., if I have two instances to compare:

A (reference): This is a book!
B (generated): It is a BOOK.

And I got a score of, let's say 98.0, is this mean the generated text (B) is 98% matching to the reference one?

Best
