The total repetition rate of HowNet = repeated words/total words 100%, and the chapter repetition rate = repeated words/total words 100%. In the duplicate checking report of HowNet, red represents the copy proportion part and green represents the quotation part. HowNet duplicate checking is based on chapters. Eight consecutive words are judged as "repeated sentences" and 13 consecutive words are judged as "repeated paragraphs".

The duplicate checking rate of HowNet is only one of the indicators to measure the repeatability of papers, and it is the embodiment of academic integrity. When writing a paper, we should not only pay attention to the duplicate checking rate, but also pay attention to academic integrity and academic norms, and we should not copy or plagiarize other people's achievements.
