Based on the "Education Big Data Alliance Platform", papertime gives priority to obtaining educational data resources, and adopts multi-level fingerprint comparison technology and deep semantic recognition technology to realize "real-time duplicate checking, online modification and synchronous weight reduction" in one step.

In order to provide users with the most rigorous and responsible test results, the system will no longer distinguish between "footnotes" and "quotations", nor will it automatically identify the author's own papers and documents. The detection system is a tool to provide users with the basis for revising papers, and whether the similar parts (red letters) displayed by the system belong to normal references will be left to users for approval.
