Paper duplication checking is to check whether there is plagiarism or other academic misconduct by comparing the papers uploaded by users with the documents in the duplication checking system. The duplicate checking system generally determines the similarity of texts by analyzing the language structure, semantic similarity and citation rules in the texts. The specific duplicate checking method can be divided into the following steps:

Users upload papers: users upload papers that need to be duplicated to the duplication checking system.

Automatic duplicate checking by the system: The duplicate checking system will perform segmentation detection according to the title, keywords, text and other contents of the paper, and record the repetition rate.

Comparing with the resource database: The duplicate checking system will compare the papers uploaded by users with the compared documents in the resource database to establish a fingerprint index.

Test results: The duplicate checking system will calculate the overall duplicate checking rate of the paper according to the comparison results and feed back the results to users. Users can make targeted modifications according to the repeated parts in the duplicate checking report, so as to reduce the repetition rate of papers.

When re-checking papers, we should also pay attention to maintaining the accuracy and credibility of documents, and we should not fabricate data or sentences at will in order to reduce the repetition rate.
