First, the citation format does not meet the HowNet recognition standard.

The identification and citation content of HowNet detection system is that the reference documents meet the identification standards of HowNet. If the citation format of the reference is not standardized, the HowNet detection system may mark the reference in red to calculate the repetition rate, and will not detect the citation rate.

Second, the quoted content is too short.

If the citation content is too short, HowNet can't match the citation content, so it can't detect the citation rate.

Third, the quoted content has been modified.

If the quoted text content has been modified, then the content you quoted cannot match the literature source of HowNet, and the modified article content may be considered original by HowNet.

Four. The cited documents are not marked.

For hownet detection system, if you want to detect the citation rate, you must mark the cited documents and all the cited documents, otherwise you will not detect the citation rate (hownet detection system automatically recognizes very little).

Verb (abbreviation of verb) reference source does not belong to HowNet.

If the source of the cited content does not belong to HowNet, HowNet cannot detect the citation rate.

Rules and principles of duplicate checking of HowNet papers;

1. HowNet uses the most advanced fuzzy algorithm to check duplicates. If the overall structure and outline are interrupted, it may lead to the inconsistency between the first detection and the second detection of the same article, or the first detection has no red mark and the second detection mark is red. Therefore, when modifying the repeated content, try to change the sentence pattern. Please don't disturb the original outline and structure of the paper.

2. After the whole paper is uploaded, the system will automatically detect the chapter information of the paper according to the directory generated by the article. Then the system will check the papers in this chapter. The copy of each individual chapter can be compared with the gray content of the same directory and does not participate in text detection. Otherwise, it will be automatically segmented according to 10000 characters around the detection, and the directory may be regarded as a text detection and may be marked in red.

3. China Knowledge Network has set a threshold to check the sensitivity of the system. The threshold is 5%. No plagiarism or quotation below 5% can be found in a paragraph. This situation is very common in large occasions. A paragraph or concept in a paragraph. For example, if the test paragraph 1 has10,000 words, references to single articles with 500 words or less will not be detected.

4. The condition of hownet paper detection is that 13 words that appear similar or plagiarized continuously will be marked in red, but three preconditions must be met: the number of words cited or plagiarized in a document and the number of words that can be realized in each detection paragraph. More than 5% can be detected as red.

5. Hownet detection system will automatically identify references, and references will not participate in text detection. Also deleted. In the HowNet test report, the references are displayed in gray font, indicating that they did not participate in the test. Of course, if the reference format is completely correct, this will be automatically excluded. Otherwise, the references will be tested as text, resulting in all references being marked in red. Higher grades!

6. HowNet duplicate papers are detected as a whole upload, and PDF or Word format may affect the detection results. Due to the detection of uploaded PDF, PDF will have more text conversion processes than Word.

This process may destroy your original correct directories and references. Content and reference will be confused, resulting in incorrect system identification. It's marked in red. Especially those English catalogues and most English references contain a large number of English characters. If English is marked in red, the overall repetition rate will increase greatly.

7. As far as quotation is concerned, the whole paragraph should be quoted. If you quote a sentence, HowNet will not recognize the specific sentence in the article you quote. So the bigger the offer, the better. References must be identical.
