The paper duplicate checking rule of HowNet is to check the papers through the paper duplicate checking system to see if there are plagiarism and duplication. The high repetition rate of papers will have serious consequences, from delaying graduation to canceling degrees.

Health census is also a popular duplicate checking system outside HowNet. Like HowNet, the VIP detection system also has a special document database. Therefore, it is impossible to draw a concrete conclusion by comparing the health census with HowNet, because the databases of the two systems are different.
