While it’s a good thought, I think this runs the risk of being severely unrepresentative of reality because most people will not read this and continue to use these terms in their own disparate ways.
You do bring a good point about not speaking the same language, though. Even those who speak perfect English tend to have different interpretations of the more abstract words. As others have said, it’s down to being familiar with the reviewer’s tastes enough to form your own (hopefully consistent) understanding of each term.
