The specific concepts of duplicate checking rate are plagiarism rate and citation rate. Test the similarity between your article and others' papers with professional software to prevent plagiarism. That's basically what it means. One is that the self-writing rate is written by yourself, and the other is that the copying rate is copied by you.

There is also a citation rate, that is, those marked with citation symbols are reasonable citations of other people's information.

Experience in modifying the repetition rate or plagiarism rate of papers;

CNKI is continuous and the same number of words cannot exceed 13, and Wanfang is continuous and the same number of words cannot exceed 15. Otherwise, it will be marked and counted in the repetition rate. The school's rule is that the repetition rate of CNKI testing cannot exceed 30%. There will be errors in the results of the two databases. Generally, CNKI will be stricter. Check with Wanfang first, then revise the sentence repeatedly against the repeated paragraphs, and finally check with China HowNet, so you can rest assured.

First, the 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. The comparison databases include: online publishing database of academic journals in China, full-text database of Chinese doctoral dissertations/full-text database of excellent master's dissertations in China, full-text database of important national conferences, full-text database of important newspapers and periodicals in China, full-text database of patents in China, personal comparison database and other comparison 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 method of revision, 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.

1) When HowNet checked the duplicate, the yellow text was "quote" and the red article was "suspected plagiarism".

(2) When checking the duplication of HowNet, only the text part is checked, and the graphics, formulas edited by mathtype and word field codes are not checked (if you want to know which parts HowNet should check, you can choose All-Copy-Paste Selective-Keep only the text). It is recommended to use mathtype to edit formulas, instead of the formula editor that comes with word.

(3) The tables edited by 3)word and excel can be found out. In some cases, you can choose to put the screenshot in the newspaper! The author has read some students' own coefficients and found that they are heavier than others. The data determination coefficient cannot be changed, so I want to cry. ...

(4) The citation of references should also count the repetition rate (including within X% required by the school)! Therefore, it is best to rewrite your own words when quoting other people's literature.

(5) Check the duplicate of HowNet with "chapter" as the unit. For example, "cover", "abstract" and "introduction" will be regarded as separate chapters, and each chapter will produce a test result indicating the repetition rate. Each chapter has a separate repetition rate, and the full text also has a total repetition rate. In some schools, when deciding whether a paper passes the duplicate check, not only the repetition rate of the full text is required, but also the repetition rate of each chapter is required.

(6) The duplicate checking of HowNet is indeed based on "13 words that are repeated with other articles", which is consistent with what some authors on the Internet said before. If you can change your paper into any sentence and make sure that any consecutive 13 words are different from other articles, HowNet can't find it.

(7) However, if you have a place where more than 65,438+03 words are duplicated with other articles, HowNet's server will conduct a fuzzy search around this place, and simply add up the words such as "de", "dang" and "but" to separate 65,438+03 words, which will be detected in most cases. These fuzzy searches are sometimes silly, which may link an article about how to raise pigs with your article about architecture and say that you are suspected of plagiarism! In this case, you can "hehe" yourself!

(8) There are no books and textbooks in the database of HowNet. However, students who copy this book should pay attention to the fact that the part you copied may be copied by other articles and will be repeated during the test. This kind of situation often happens, especially some classical theories, which have been used for hundreds of years. Someone must have written it!
