Reference to be calculated in the repetition rate. The coincidence degree of papers is the similarity or coincidence degree of academic papers in content, which is usually used to detect whether the papers are plagiarized. Generally, colleges and universities define the coincidence degree of more than 30% as plagiarism, that is, the paper failed to pass the examination.
Whether a quotation belongs to plagiarism has nothing to do with marking the source. These all depend on the threshold of the system. The sensitivity of this detection system is set to a threshold of 3%. In terms of the number of words in a paragraph (or chapter), plagiarism or citation of a single document below 3% cannot be detected.
