The difference between paperyy and HowNet is generally 5%- 10%. Because of the differences in algorithms and databases of different paper duplicate checking systems, the duplicate checking results can not be consistent, and each paper is different, which involves specific analysis of specific problems.

However, if the difference between paperyy and HowNet is 5%- 10%. It is no problem to use paperyy system to check the duplicate of the first draft of the paper, but it is safer to use the duplicate checking system consistent with the school for the final draft of the paper.

Paper document duplicate checking system

PaperYY's paper duplicate checking system covers 10 data types and 20 professional parameters, including 16 databases, with 5 billion comparative data. At the same time, it supports the identification of contents, covers and references, as well as the extraction of quotations. The resource system is relatively perfect.

PaperYY not only gives more accurate duplicate checking results, but also clearly marks the optimization scheme of the paper in the test report of PaperYY. According to the opinions of duplicate checking, it is very cost-effective to reduce the repetition of the last paper, such as modifying the "revision suggestion" or clicking "automatic weight reduction" directly.
