Only the postgraduate papers that have been checked by HowNet detection system will be included in the HowNet joint comparison database and put on HowNet, and the papers of the second year after being checked will be included in official website. Many graduate students will use the HowNet detection system to check their papers in advance before submitting them to colleges and universities, so as to correct all kinds of academic misconduct in the papers and ensure that colleges and universities can successfully pass the duplicate check before the duplicate check of graduate papers.
