Published papers need to be checked. When submitting a manuscript, the staff of a journal or conference will double-check the contents of the manuscript to prevent academic misconduct.

Periodicals or conferences usually use professional duplicate checking tools, such as HowNet and paperfree. These tools can detect the parts with high similarity in papers and help staff to determine whether the papers need to be revised or meet the requirements of journals or conferences.

In the process of duplicate checking, journals or conferences will also evaluate the originality of the paper to ensure that the content of the paper is novel, unique and of academic value. If the repetition rate of the paper is too high, or there is academic misconduct, then the paper may be rejected or requested to be revised.

Before publishing a paper, authors are advised to check and revise themselves to ensure the originality and quality of the paper. At the same time, the author should also pay attention to the requirements and norms of journals or conferences to ensure the smooth publication of papers.
