Although the duplicate checking database used by paperpass is different from HowNet and Wanfang, the duplicate checking is very accurate. The duplicate checking method is based on the continuous appearance of 13 characters, which will be judged as duplicates.

In other words, if more than 13 words are similar, they will be marked red by the system software and calculated into the repetition rate. When paperpass checked the duplicate, the yellow text was "citation" and the red article was "suspected plagiarism". The software repetition rate of paperpass duplicate checking system has a threshold, which is about 5%. If this threshold is exceeded, the paper will be judged as unqualified by the duplicate checking system.

Repeated inspection method

HowNet's paper format detection system is the whole paper submission detection, and HowNet system will divide the whole paper into chapters and carry out subsection detection. The modification of paper format will have a great influence on the test results. The repetition rate can be modified by changing the paragraph division of the paper.

Database paper detection system generally includes some graduation papers, periodical papers, some online articles, meeting records and so on. , to match your paper. HowNet doesn't include some books and newspapers. When I graduated from 20 15, a friend plagiarized a long paragraph from the book, and the test results were not detected.

References and citations can be identified by the detection system of papers on HowNet, such as labeling references and citations. Footnotes and endnotes do not participate in data comparison, so the quoted text must be in the correct format. References must be true, and if the author fills in the references at the wrong time, it will be detected as plagiarism.

Word matching HowNet papers are strict. As long as more than 13 words match, it is considered plagiarism, provided that the HowNet threshold is met, and the HowNet threshold is 5%. In other words, 1000 characters in a paragraph will not be detected if the number of plagiarized words is less than 50 characters. On the other hand, it is considered plagiarism.
