Principle of duplicate checking:

1. hownet dissertations are tested as a whole article, and the format may have an impact on the test results. It is necessary to submit the final submission format for testing, so as to minimize the impact, and dozens of blocks may not be detected. Papers over 30,000 words can be ignored.

Comparative databases include: online publishing database of China academic journals, full-text database of China's doctoral dissertations/full-text database of China's excellent master's dissertations, full-text database of important national conferences, full-text database of important newspapers and periodicals in China, full-text database of China patents, personal comparative database and other comparative databases. Some books are not in the HowNet Library and cannot be detected.

2. After the paper is uploaded, the system will automatically detect the chapter information of the paper. If there is automatically generated directory information, the system will detect it chapter by chapter, otherwise it will automatically detect it section by section.

3. It is normal for some students to report that they explicitly quoted or copied paragraphs or sentences from other documents in their own paragraphs, and why they didn't detect them. China Knowledge Network has set a threshold for the sensitivity of this detection system, which is 5%. In terms of paragraphs, plagiarism or quotation below 5% cannot be detected, which is common in clauses or small concepts in large paragraphs. For example, if the detection paragraph 1 has 10000 words, a single document with less than 500 words will not be detected. In fact, here also tells the students a modification method, that is, never choose an article to quote from paragraph plagiarism, try to choose as many documents as possible, and intercept a few words from one article, so that it will not be found out.

4. How to detect plagiarism in a paper? The condition of hownet paper detection is that 13 words with similar or plagiarized words will be marked in red, but the precondition in 3 must be met: that is, the sum of A documents you quoted or plagiarized should reach 5% in each detection paragraph.
