There is no fixed correspondence between PaperPass and HowNet, because they use different databases and algorithms. Therefore, it is impossible to accurately predict the duplicate checking rate of HowNet.

Generally speaking, if the duplicate checking rate of PaperPass is 23%, the duplicate checking rate in HowNet may be higher or lower than this value. Students can make corrections according to the duplicate checking report of PaperPass to reduce the duplicate checking rate of HowNet.

HowNet is the system used by most schools, and the database is the most authoritative and standard in China at present. Paperfree paper duplicate checking is an auxiliary revision reference, which supports the functions of machine weight reduction and online weight change, covers about 70% of HowNet data, and can reduce the absolute cost of preliminary testing fees. After the finalization, for the sake of safety, it is recommended to use HowNet!

It should be noted that no matter which duplicate checking tool is used, the results should be taken seriously and modified and improved accordingly.
