How much should academic papers generally be checked for plagiarism?

Academic papers generally check for plagiarism no more than 30%.

However, many schools now limit the plagiarism check rate of academic papers to more than 20%. Some schools are stricter and may require that the duplication rate of papers does not exceed 10%.

The official term for paper plagiarism checking is academic misconduct detection, which means that bad behaviors such as plagiarism and plagiarism should be suppressed with a rigorous and honest attitude, and a positive social atmosphere should be created for society.

Extended information:

For any document that needs to be detected, the system first processes it hierarchically, based on chapters, paragraphs, sentences, etc. Fingerprints are created separately, and the same technology is used to create fingerprint indexes for comparison documents in the comparison resource database.

Such a hierarchical multi-level fingerprint structure not only satisfies our rapid detection of ultra-long documents, but also satisfies the system's accuracy and accuracy because our minimum fingerprint granularity is sentences. High requirements for detection rate. In principle, as long as there is an identical sentence between the detection document and the comparison document, it can be discovered by the paper detection system.
