Generally speaking, if the character 13 in a paper is similar or the same as the character in the database, it is judged to be duplicate. In addition, the duplicate checking system will also deal with the cited part of the paper to eliminate the influence of the quoted content on the repetition rate. Commonly used duplicate checking systems include HowNet, VIP, Wanfang, paperfree, papertime, etc. According to the requirements of schools or academic institutions, select the appropriate duplicate checking website for testing.
It should be noted that different duplicate checking systems and databases may judge the repetition rate differently. Therefore, when choosing a duplicate checking system, you need to choose a duplicate checking system suitable for your paper and read the contents of the duplicate checking report carefully to reduce duplication.
