What sort of text? If it's long written stuff, I'd split it into paragraphs then loop through each paragraph and split into sentences, then loop through each sentence and split into words - count the number of matches of words in the related sentence in the original text and if a sentence a score based on how many matching words, and then combine the sentence scores to give paragraph scores, and paragraph scores to give overall scores. Decide on a limit and if the total score limit is over that, consider it a minor change, else it's a major.
