More over, you are clearly not in violation of copyright if you are talking about statistics about the material. In your example, printing out a "there were 7000 instances of the word 'the'" is certainly not a violation. A ML model is just a huge pile of these statistics.

However, saying "the first word of the book is 'The'" would not be a violation, while repeating that for every word in the book, as a whole, would be one.
