But this situation is uncertain, and some quotations will be rechecked and marked red.

Take the latest version of HowNet as an example, the quotation is green, the plagiarism is red, the number of repeated words = green word+scarlet letter, and the repetition rate = the number of repeated words ÷ the total number of words. Among the hundreds of papers I have read, only one compassionate school requires that the "copy ratio excluding quotations" be less than X%, while other schools all look at the "copy ratio of total words". In other words, the number of words cited+plagiarized must be less than X% of the number of words in the full text. Even if it is identified as a citation, it still needs to be revised, otherwise the repetition rate is only up up up!

Paper citation should meet several key points:

1. If your paper is copied by HowNet, first of all, the article you quoted should be downloaded from HowNet, and it must be included in HowNet. Otherwise, it is not in the paper database, and it is naturally repetitive.

2. The sentence quoted in your article really comes from a sentence in the reference you downloaded. You can't just write a sentence and quote a reference. It must be wrong.

3. The citation format should be correct, which is the mistake of more than 90% students. Some students even type a [1] directly when quoting, which is definitely wrong. Before citation, the references should be sorted and arranged in the order cited in the article. Then put the reference number on it and insert a footnote at the end. At this time, the reference will automatically become [1] in the upper right corner, so the reference is successful.
