As long as the citation part appears in the paper to be detected, the duplicate checking system will check the citation part, calculate the citation rate of the document part, and automatically mark it in the paper duplicate checking report. When a user refers a document to a paper, the correct citation format will be set. In duplicate checking, the duplicate checking system will identify the cited part, calculate the proportion of the total words of the cited part to the total words of the paper, and finally mark it in the duplicate checking report.

It is normal to quote documents in the process of writing a paper, and you need to read a lot of documents before writing. Therefore, as long as the author uses the correct citation format when writing a paper and the citation part is not too large, it will not have any impact. HowNet papers will be automatically identified as quoted parts and marked in green font. However, it must be noted that in the process of quoting, never quote in a big way, because this will also be detected as plagiarism.

Criteria for judging plagiarism in papers

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.

The content of the paper is a patchwork of many other people's works.
