First of all, quoting famous sayings is a very common behavior in paper writing. As an academic work, graduate thesis needs to cite previous research results to support its own views. But whether the quoted famous sentences will be detected by the duplicate checking system is a problem that needs to be discussed. The duplicate checking system usually determines whether there is a part with high similarity by comparing the words in the paper with the contents in the existing literature database. Therefore, if the quoted famous sentences have relevant records in the database, they may be found out in the process of duplicate checking. But in general, the duplicate checking system will exclude the quoted famous sentences from the comparison scope, because the quoted content is not original.

Next, when users use the system, they need to upload the paper to the system, and the system will automatically compare the paper with the existing documents and give a similarity report. Users can modify or delete the similar parts of the paper according to the similarity report to ensure the originality and academic integrity of the paper.

To sum up, the famous sentences quoted in the search may be detected, but the duplicate search system usually excludes the quoted content from the comparison range. In order to ensure the originality and academic integrity of the thesis, graduate students should quote appropriate famous sayings and follow relevant academic norms when writing the thesis. In addition, the duplicate checking system can be used to ensure the originality of the paper and avoid plagiarism. The system can compare full-text papers and provide similarity reports to help graduate students modify similar parts and improve the quality of papers.
