PaperFree consists of more than 90 million academic journals and dissertations and an Internet webpage database with a number of more than 654.38 billion. However, there are Internet literature resources and Internet resources (including forum resources such as post bars) within the detection range of HowNet. Obviously, the network resource PaperFree has more advantages, so PaperFree is stricter than HowNet.
Second, PaperFree is not as advanced as HowNet.
On the premise of correct format, HowNet can identify directories and references and automatically eliminate them without participating in text detection. At the same time, we can also check the duplication by chapter according to the catalogue and detect the citation rate according to the references. PaperFree is clumsy. PaperFree can't scientifically identify catalogs and references and test them as texts. Obviously, catalogues and references are very easy to repeat, so the result of paperless duplicate checking is more stringent than HowNet. How to write the table of contents and references correctly can be explained in more detail by searching for article keywords on "Academic Misconduct Network".
Third, the rules and principles for calculating the repetition rate are different.
PaperFree red plagiarism is serious, yellow plagiarism is slight, only green security; The red plagiarism, yellow quotation and repetition rate of HowNet are the proportion of repeated words to the total number of words. Obviously, the calculation of PaperFree is too high, so PaperFree is more strict.
Generally speaking, PaperFree is not very scientific, a little too high. Marking in red is easy to be repeated. Don't take paperless as a lifeline. After all, colleges and universities are generally based on HowNet. Finally, it is safer to test HowNet on Academic Misconduct Network. There are also some undergraduate colleges that take paperless as the standard, but this situation is rare. Be sure to find out which duplicate checking system is used in our school before duplicate checking, which duplicate checking system shall prevail!
