First, log in with a WPS account, open the paper to be detected in WPS, and then find "Paper Duplicate Checking" under "Paper Assistant" in the navigation bar of WPS. Then, there are two options, namely "general paper duplicate checking" and "paper title duplicate checking". Then you can directly connect with the common and reliable duplicate checking engines such as PaperPass, Wan Fang Data, PaperOK and PaperTime.

Finally, I would like to remind you that paper duplicate checking only supports uploading documents in doc, docx and wps formats. The number of words in the documents ranges from 1000 to 150000, and the size cannot exceed 30M. For duplicate documents, it is suggested to manually delete the cover, abstract, references, thanks and other non-body parts of the paper.
