The content of the paper generally includes reference materials, headers and footers, directories and so on. When checking the repetition rate, the information network will identify the paper catalogue and test it chapter by chapter, showing the repetition rate of each chapter and only the total repetition rate. The cover of the school can't be changed casually. Reference materials are also necessary and can't be wrong.

No matter how to check the copy of HowNet, you need to check the contents of references. Because the final draft uses China HowNet paper system, not other software, so the results of other software are zero, which is not authoritative, because in some schools, only the results of cognitive network are checked.

Extended data:

1. The duplicate checking system stipulates that the citation of a paper shall not exceed 5% of the words in the full text of the cited article. If it exceeds this limit, it can't be called quotation, but plagiarism.

2. Most final papers are checked by the paper duplicate checking system of HowNet, which will count the cover, abstract, table of contents, abstract, text, references and even footnotes of the papers. That is, all the words on the uploaded paper word will be counted. At the same time, the number of words in the paper stipulated by the school is also subject to this.

3. Different schools have different requirements for the repetition rate of papers, but they all have a limited value. Under normal circumstances, colleges and universities require undergraduate students not to exceed 30%, master students not to exceed 20%, and doctoral students not to exceed 10%. Of course, some famous schools stipulate that undergraduate courses should not exceed 20% and master's courses should not exceed 10%.
