Every school is different, and the full-text repetition rate is below 30% (while some schools have undergraduate courses of 20%). There should be no requirement for the repetition rate of each chapter. Every school will make detailed rules, and the school will also give them places to check the repetition rate-basically China HowNet. Call the teacher specifically. Every school in every field has different requirements.
The special function of nouns in related duplicate checking system;
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 the self-writing rate, which is self-writing.
One is the copy rate, which is what you copy.
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;
The number of consecutive words in China HowNet cannot exceed 13, and the number of consecutive words in Wanfang cannot exceed 15. Otherwise, it will be marked and counted in the repetition rate. Our school stipulates that the repetition rate of CNKI testing should not exceed 30%. There will be errors in the detection results of repetition rate between the two databases. Generally, CNKI will be stricter. Check it with Wanfang first, then revise it repeatedly against repeated paragraphs and sentences, and finally check it with CNKI, so you can rest assured.
Now is the critical period for students to write their graduation thesis. Many students need to use some documents in their thesis writing, which involves a problem, how to use other people's documents, how to form good academic norms and avoid plagiarism. This is a very urgent problem now, but many of our classmates lack strict training and don't know when to copy and quote other people's articles. Here I want to make a simple discussion on this issue. This can only be regarded as a topic, and the purpose is to discuss this topic with you. What is plagiarism? Simply put, using other people's words or opinions without specifying them is plagiarism. "Plagiarism does not indicate the source of other people's words, but it is marked with quotation marks, which constitutes plagiarism. The definition of plagiarism in the Author's Handbook of the American Modern Language Association is:' Plagiarism refers to using other people's opinions or expressions in your writing without properly indicating the source. ..... This includes repeating word for word, copying other people's works, or using opinions that don't belong to you without giving proper quotations. It can be seen that there are two kinds of plagiarism in papers: one is plagiarism, which uses other people's opinions without indicating them, making people mistakenly think they are their own; One is plagiarism, copying other people's written expressions, not indicating the source, using quotation marks, making people mistakenly think that it is your own expression. Of course, the former is more serious than the latter, because the paper pays attention to the originality of ideas. As for popular articles, it is different, because we don't pay attention to the originality of opinions, so we don't need to indicate the opinions from others one by one, only pay attention to whether the written expression is plagiarized. "So how to use other people's literary works? Harvard University in the United States pointed out in its relevant student handbook, "If your sentence is very similar to the original data in terms of viewpoint and sentence structure, and the conclusion is similar to the quotation instead of repeating it in your own words, even if you indicate the source, it is plagiarism. You can't simply change a few words or summarize the original materials. You must completely reshape your summary with your own language and sentence structure, or quote directly. "Quoted from the relevant regulations of Harvard University, I saw the original text 1 years ago, and now I can't find the source. It can be seen that the use of other people's content must be completely rewritten, otherwise it is suspected of plagiarism. But here we should avoid patchwork and kneading. In short, we must respect other people's intellectual achievements and reflect what you have done and what others have done in the article. Of course, it is still difficult to do this now, but I think we should at least have this awareness, because in the concept of plagiarism, besides emphasizing that there is no indication, we also emphasize that it is not intentional. Many of us make mistakes because we don't know what plagiarism is and how to avoid it, so it is very important to know what plagiarism is. In reality, it is difficult for our classmates to write a graduation thesis of about 10000 words without plagiarism, but we should at least try our best to avoid serious plagiarism subjectively and gradually form good habits.
In China, it is the HowNet /VIP/ Wanfang system, and the resources here are constantly updated. Every year, in addition to the confidentiality requirements, graduates' papers are basically collected by these three systems as a comparative resource library, so we can't be careless! ! China has three systems. HowNet /VIP/ Wanfang HowNet is not open to individuals, Weifeng Wanfang is open to individuals. Wanfang does not test Internet and English, but HowNet and VIP test Internet and English. At present, all schools must pass the exams for master's and doctoral dissertations to qualify. Undergraduate graduates, most of whom are 2 1 1 engineering key universities, take spot checks to check the repetition of undergraduate graduation thesis. Plagiarism or citation rate is too high, once it is found to be over 30%, the consequences are quite serious. Less than 50% of the students are similar, their graduation will be postponed, and more than 50% will have their degrees cancelled. After studying tens of thousands of dollars in college, plus several years, I can't find a job and get a degree, which is very sad. However, all detection systems are machines and have inherent detection principles. As long as you know the internal inspection principle, system algorithm and law, you can still pass the inspection and graduate easily through repeated revision of the inspection report.
Today, all graduate dissertations will pass the "Academic Misconduct Test" of China Knowledge Network, even if they are not blindly judged. The original intention of this system is actually very good, which can play a warning role for graduate students who are about to enter the field of scientific research in China to some extent: put an end to plagiarism and study hard. However, the so-called "everything in the world, where there is a spear, there must be a shield" philosophy, China HowNet's "academic misconduct detection system" is not perfect. There are two reasons: first, the current pattern recognition technology is not advanced enough; Secondly, the current machine recognition is not intelligent in meaning recognition. The consistent view of the Explorer Pavilion is "strategic contempt, tactical importance" and "know yourself and know yourself, and win every battle". If you want to break the enemy, you must anticipate the enemy; To pass the academic exam, of course, we must first understand the mystery of this exam.
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. 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 the paper in sections, otherwise it will automatically detect the paper in sections.
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.
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) Hownet takes "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!
Of course, some students think it is ok to rewrite it in their own words. But the reality is: these classic theories are also likely to be "marked red" when written in their own words, because these classic theories have been written repeatedly for n times! Whether you will be "marked red" depends on your personality! When the author checked the reply, there was a passage that was changed three times in his own language, and it was still marked red, which made people laugh and cry. I can only say that the author's character was a failure at that time. I hope this article published now can leave some character for tomorrow!
(9) Some contents on the network are also in the database of HowNet. For example: Baidu Library, Knife Baba, Douding.com, Interactive Encyclopedia and Baidu Encyclopedia. When I checked the duplicate, I even met many wonderful websites, such as "Oriental Fortune Blog" and "NPC Economic Forum". Therefore, we should be careful when choosing network content.
(10) Few foreign documents are stored in HowNet database. Encourage everyone to read more foreign documents, learn more advanced foreign scientific knowledge and engineering technology, and translate and apply them to the papers on China's socialist modernization!
(1 1) It is suggested that all schools check the duplicate online at their own expense. The test report will "mark red" the repeated places and modify them first.
(12) After reviewing the exam, students should not take it lightly. Because the most perverted and irritating part of HowNet's check is coming: there is no "red label" the first time, and there may be a "red label" the second time, saying that you plagiarized. If you are willing to spend money, spend money to check it online until it is lower than the repetition rate required by the school.
(13) There are "Wanfang", "HowNet" and "paperpass" commonly used in online duplicate checking. paperpass is the loosest, Wanfang is in the middle, and HowNet is the strictest.
Wanfang's database is incomplete, and the repetition rate of discovery will be 5% lower than that of HowNet. Hownet is "continuous 13 words" even if it repeats, so the repetition rate is higher!
It is best to use Wanfang for pre-inspection, and the pass rate is generally higher after the change.
