In the process of duplicate checking, the system will automatically divide the papers that need duplicate checking into chapters, and then compare the contents of each chapter with the documents in the database. For the repeated parts, the system will mark and calculate the number of repeated words, and finally get the repetition rate of the paper.
It should be noted that different duplicate checking systems may have different matching algorithms and databases, so the query results may be different. At the same time, paper duplication checking is an auxiliary tool, which needs to be combined with manual review and subjective judgment to determine the quality and level of the paper.
