First of all, we should focus on the citation part of the paper. The paper duplication checking system usually compares the cited part with other published articles to detect whether there are too many direct quotations in the paper without proper comments or references. Therefore, when reducing the weight of papers, it is necessary to re-examine and modify the citation methods. By reinterpreting or reorganizing the quoted content, direct quotation can be avoided, and comments can be added appropriately to increase the originality of the paper.

Secondly, we also need to focus on revising the repeated content in the paper. Duplicate checking system usually detects duplicate parts by comparing words and sentences in papers. Therefore, when reducing the weight of paper, we need to pay attention to avoid reusing sentences and paragraphs that express the same meaning. Repetition can be reduced by changing the wording, adjusting the sentence structure or optimizing the logical framework of the paper.

In addition, special attention should be paid to the formula and data part of the paper. The duplicate checking system will also detect the duplication of mathematical formulas and data in the paper. When reducing the weight of the paper, we can try to change the expression of the formula, or choose to insert different data again to increase the originality of the paper.

Finally, when reducing the weight of papers, we should also pay attention to the use of appropriate references and citation formats. The duplicate checking system will also compare the references in the paper with published articles to detect whether there are errors in annotation or citation format. Therefore, when reducing the weight of papers, it is necessary to carefully check the sources and citation formats of references to ensure that they meet academic norms and requirements.
