1, citation position is an important index to measure whether the paper duplication checking system can accurately identify plagiarism in articles. The accuracy of citation position can help duplicate checking system to analyze articles better, thus detecting plagiarism more accurately.

2. Marking and citing papers can reduce the duplicate checking rate. First of all, quoting can improve the quality of papers. Citation can make the paper more authoritative and provide valuable insights for the paper.

3. Labeling and quoting can also hide the original plagiarism in the paper. Because citation can combine papers with original content, original content and cited content can be compared separately in duplicate checking, thus reducing the duplicate checking rate.

Techniques to reduce duplicate checking rate;

1. HowNet's reexamination report modifies the repetitive parts of the paper, but this does not mean that the weight can be reduced by adding modifiers and conjunctions.

2. Because the duplicate checking system is not so low-end, they use fuzzy algorithm. In other words, it is generally necessary to modify the repeated parts, and at least half of the contents can be modified, preferably to the extent that the human eye cannot judge the repetition.

3. Most paper duplicate checking systems can't identify pictures, so they can't check them. Therefore, if there is repetition in the paper, students can use pictures instead of repeated words appropriately, but don't abuse pictures too much, because this will affect the quality of the paper.

4. If there are many repetitions in the paper, you can use the original rewriting method, first read through the repeated parts, and then look at the context, and think for yourself what kind of sentences can replace the repeated parts, which will not affect the quality of the context.
