Here is my use case:
I want to post a review. I want the review to not only contain a rating, but also have a short human readable explanation of what each rating means to me. For instance, my scale works like this:
1 - Problematic or offensive, but not necessarily badly crafted. Beautiful prose that is racist, for example, would be one star rating.
2 - Did not enjoy it, or it is badly made.
3 - Default rating. Nothing exceptional.
4 - Enjoyed it, or had something interesting about it.
5 - Truly a great and enjoyable work that comes out once in a blue moon.

This might be a different rating from someone else, who might rate 1 as disliked immensely. So I want to provide this informational map.
