In the past, papers were reviewed by peers and revised by editors after publication. Therefore, the academic community generally believes that once a paper is published, it means that the author's thoughts and research results have been clearly expressed. However, with the popularity of the Internet and the emergence of various paper duplicate checking systems, people pay more and more attention to paper duplicate checking.

So, do published papers still need to lose weight? The answer is yes. Although the papers have been peer-reviewed and edited after publication, at the same time, others can access and read them through the Internet. This increases the risk of plagiarism or plagiarism. Therefore, in order to ensure the originality and quality of the paper and protect the author's academic reputation, it is very necessary to check the published papers. In the early stage, you can use paperfree or papertime for preliminary modification and duplicate checking, which supports online and real-time duplicate checking, which is very convenient.

In addition, the use of duplicate checking system is not limited to pre-publication detection. When other researchers cite or refer to published papers, it is also very meaningful to check the duplication of papers. This can ensure that the quoted content is not duplicated and plagiarized, and also ensure the accuracy and reliability of the quotation.
