Paper detection mainly detects the repetition rate of papers, that is, the proportion of words that are repeated with other people's research results and documents. Specifically, the paper detection system will compare the submitted papers with the existing documents in the database to detect whether there are academic misconduct such as plagiarism, plagiarism and repetition in the papers.

In addition to detecting the repetition rate, the paper detection system will also check the format, citation methods and references of the paper to ensure the standardization and academic nature of the paper.

Different duplicate checking systems have different algorithms and databases, so the duplicate checking results will be different. For the first draft of the paper, it is suggested that the paper series free duplicate checking software such as paperfree, papertime and paperday can be used for testing, and for the final draft, the duplicate checking system required by the school can be used for testing. Ensure the accuracy and effectiveness of duplicate checking.
