2. In this case, be sure to contact customer service in time. There will be an option to contact customer service in the lower right corner of the homepage of the duplicate checking website. Click to enter and ask if there is any problem if the duplicate checking rate is 0.
3. Solution: If the duplicate checking rate is 0, you can consult your tutor. Some schools can allow papers with a duplicate check rate of 0, while others do not. If it is not allowed, it is necessary to modify the paper accordingly, and then find a regular duplicate checking website to check the duplicate.
4. The citation content is too short: when the citation content is too short, the paper duplicate checking system cannot match the citation content, and the citation rate will be zero. Cited content is modified: if the quoted text content is modified, the quoted content can't match the literature source of the paper duplicate checking system, so the citation rate can't be detected naturally.
5. Several cases where the repeated citation rate is 0%: the citation format does not meet the HowNet identification standard. Hownet detection system needs references to identify citation content, so as to meet the identification standard of Hownet. If the citation format of the reference is not standardized, the HowNet detection system may mark the reference in red to calculate the repetition rate, and will not detect the citation rate.
6. Papers with incorrect citation format, only those with correct citation format, will be recognized by the paper duplicate checking system, which is considered as the repeated citation rate of the cited content. Therefore, when the citation format is incorrect, it means that there is no citation content in the paper, and there will be no citation rate.
