First, the scope of paper duplicate checking.

1. Title, 2. Abstract, 3. Keywords, 4. Content, 5. Text of graduation thesis: including preface, thesis and conclusion, 6. Thank you, 7. References, 8. Notes, 9. Appendix.

According to the format order, the paper duplication checking system will automatically identify and eliminate the non-repetitive parts.

Second, the calculation method of paper characters

Count the number of characters+spaces. Word document format does not calculate chart format and code information. Chinese papers count the number of characters, while foreign papers count two letters as one character.

Third, the criteria for judging plagiarism.

1. The words and expressions in other people's papers and works are identical or basically similar, or have been improperly deleted, individually modified or restructured.

2. The words used in the paper are not completely consistent with or basically similar to the contents of other people's works, and the format of the cited references is marked, but it has exceeded the threshold of "appropriate citation".

3. Although the citation content of the paper does not exceed the threshold of "appropriate citation", the core chapters, key parts, valuable parts or characteristic parts of the paper are duplicated with other people's works.

How to define quoting others' articles and copying others' articles in detection software? It's actually quite simple. In our paper, reference symbols are added, but in plagiarism detection software. All these are viewed in a unified way. The threshold of software is generally set to 1%. For example, an article is 5000 words, and 1% of the article is 50 words. If more than 50 words are plagiarism, even if references are added, it is also plagiarism.
