The coincidence degree of papers is the similarity or coincidence degree of academic papers in content, which is usually used to detect whether the papers are plagiarized.

General colleges and universities set the coincidence degree as 30%. In fact, if the format of the reference is correct, it will not be included in the repetition rate, because HowNet can identify the reference, and the correct reference format HowNet system can automatically identify the non-repetitive reference format and correctly identify it.
