Relatively high, generally speaking, the duplicate checking rate below 10% is considered to be relatively safe. However, the duplicate checking rate of a paper cannot be simply measured by numbers, because the duplicate checking rate is not only related to the length of the paper and the number of cited documents, but also related to the duplicate checking software used and its settings. Generally speaking, the duplicate checking rate of 20% is not very high, but the specific situation needs comprehensive consideration. The specific requirements of duplicate checking rate need to be asked by the receiving party such as journals/schools. If the requirements of the journal/school are higher than 25%, then 20% is ok.

In the process of writing a paper, if you find that the duplicate checking rate is high, you can reduce the duplicate checking rate by modifying, changing the citation format and adding your own original content. At the same time, you can also refer to the similar parts marked in the duplicate checking report to check and modify possible plagiarism and duplication. For long articles or paragraphs that need to be quoted, they should be appropriately deleted and rewritten to meet the requirements and style of their own papers, rather than directly copied. For commonly used terms and concepts, synonyms, antonyms or more specific expressions can be used appropriately to reduce the repetition rate.
