In order to ensure the originality of the submitted papers and avoid self-plagiarism, it is necessary to extract the published papers. The following provides a simple and effective method to help graduate students correctly extract their published papers in the process of duplicate checking.

First of all, you need to use a professional duplicate checking system. The duplicate checking system can compare and analyze the papers to be duplicated and published papers, and find out the parts with high similarity. When selecting the duplicate checking system, we should ensure its high accuracy and reliability to avoid misjudgment.

Secondly, create a special account in the duplicate checking system and upload your published papers to the system. The system will automatically compare the paper with the existing database to find out the parts with high similarity. At this time, it is necessary to record the reference part displayed by the duplicate checking system.

After writing down the quotation, read it carefully and check it. Sometimes, the duplicate checking system will mistake some irrelevant parts or common phrases for references. Therefore, it is very important to ensure that the cited part of the record is true and the papers published repeatedly.

When checking, you can also compare the original paper sentence by sentence to judge whether there is duplication. If it is found that the cited part does overlap with the published paper, it needs to be revised or deleted in the new paper to ensure originality.

Finally, be very careful when modifying or deleting the reference part. After deleting the parts cited in the excerpts, we should re-examine the new papers to ensure that the deleted parts will not be detected by the duplicate checking system at all.
