Can't! Although I don't know much about this piece, as far as I know, the original comparison of general articles is in the form of article information fingerprints, that is, the frequency of specific words in the article is compared after statistics, and the possibility of comprehensive comparison of the word frequency of the whole article and paragraph articles is not ruled out!
Common ways to improve originality are: reordering (adjusting the order of paragraphs), substitution (replacing some words with synonyms), abbreviation, expansion and so on!
