Today I will tell you about the principles and detection of paper plagiarism checking, the techniques and methods for passing paper plagiarism checking, and the paper plagiarism checking website and instructions. To defeat the enemy, you must know the enemy first; to pass the academic test, of course you must first understand the mystery of this level.
1. Principles of plagiarism checking
1. CNKI dissertation detection requires the entire paper to be uploaded. The format may have an impact on the detection results. The final submission format needs to be submitted for detection and the The impact is minimized, and this impact may not be detected for small segments of a few digits. Papers with more text than 30,000 characters can be ignored.
The comparative databases are: China Academic Journal Online Publishing Database, China Doctoral Thesis Full Text Database/China Excellent Master’s Thesis Full Text Database, National Important Conference Paper Full Text Database, China Important Newspaper Full Text Database, and Chinese Patent Full Text Database, personal comparison library, other comparison libraries. Some books are not in the CNKI database and cannot be detected.
2. After uploading a paper, the system will automatically detect the chapter information of the paper. If there is automatically generated table of contents information, the system will detect the paper in sections, otherwise it will automatically detect sections.
3. Some students reported that they clearly quoted or plagiarized paragraphs or sentences from other documents in their paragraphs, but why they were not detected. This is normal. China National Knowledge Infrastructure has set a threshold for the sensitivity of this detection system. The threshold is 5, measured in paragraphs. Plagiarism or citations below 5 cannot be detected. This situation is common in small sentences in large paragraphs. Or small concepts. For example: If the detection paragraph 1 has 10,000 words, then citations of less than 500 words from a single document will not be detected. In fact, students are also told here a modification method, which is to never choose one article to cite when plagiarizing a paragraph. Choose as many documents as possible and excerpt a few sentences from each article. This will not be detected.
4. How can plagiarism in a paper be detected? The conditions for CNKI paper detection are that 13 consecutive words that are similar or plagiarized will be marked in red letters, but the prerequisites in 3 must be met: that is, the total number of A document texts you quoted or plagiarized must reach 5 in each of your detection paragraphs.
2. Paper Plagiarism Detection Algorithm
1. Paper Paragraphs and Format
Paper detection basically involves uploading the entire article. After uploading, the paper detection software First, divide the sections into sections. The format of the final manuscript submitted has a great impact on the plagiarism rate. The division of different paragraphs may cause small paragraphs with dozens of words not to be detected. Therefore, we can reduce the plagiarism rate by dividing more small paragraphs.
2. Database
Paper detection is mostly based on matching published graduation thesis, journal articles, and conference papers. Some databases also include some articles from the Internet. . Let me disclose to you that many books are not included in the detection database. Previously, a friend excerpted a large amount of text from a research book, but it was not found out. It can be seen that this method is still effective.
3. Chapter change
Many students have changed the order of chapters, or extracted different chapters from different articles and spliced ??them into articles, which has almost an impact on the results of plagiarism detection. zero. Therefore, the paper plagiarism detection master advises everyone not to think that plagiarizing a few articles or dozens of articles will pass.
4. Mark references
How are reference to other people’s articles and plagiarism of other people’s articles defined in the detection software. In fact, it is very simple. We have added reference symbols to our paper, but in the plagiarism detection software. They are all treated uniformly. The threshold of the software is generally set to 1. For example, if an article has 5,000 words, 1 in the article means 50 words. If more than 50 words are plagiarized, even if references are added, it will be judged as plagiarism.
5. Word count matching
The paper plagiarism detection system is relatively strict. As long as more than 20 units of word count match, it will be considered plagiarized, but the premise is that point 4 is met. Annotation of references.
3. Seven methods to quickly pass the paper plagiarism check Method 1: Foreign language document translation method
Check the foreign language literature in the research field, especially the literature in high-level journals, such as Science, Nature , WaterRes, etc., translated the theoretical explanation into Chinese and put it in their own paper.
Advantages: 1. Everyone has different language habits, so the translated Chinese must be different. Therefore, even if the same text is translated by different people, there will be no plagiarism. 2. Reading foreign language literature can improve one's English level and expand one's horizons in professional fields.
Disadvantages: It is more difficult for students who are not good at English, especially for students who are not good at professional English.
Method 2: Change the wording
Rewrite the words in other people’s papers according to their meaning, or change the sentence structure, change the active and passive voice, or change the keywords, or by addition or subtraction. Of course, if it is a classic quote, it should still be quoted in the classic way.
Advantages: 1. After modifying the text, according to CNKI procedures and algorithms, as long as there are no repetitions of 13 consecutive words or keywords, it will not be marked red. 2. Know every word and sentence of the paper thoroughly, and be familiar with it by heart, and you will be as comfortable as a fish in water during the defense.
Disadvantages: Correcting word for word is time-consuming and laborious.
Method 3: Translate using Google and other translation tools
Use Google to translate the text in other people’s papers into English, and then translate it back, the sentence pattern and structure will change. After modifying the language errors by yourself, you can successfully avoid the duplication check.
Advantages: Convenient and fast, you can modify a large section.
Disadvantages: Sometimes it needs to be translated several times. It must be translated from Chinese to English, then to Algerian, and then to Chinese.
Method 4: Convert Picture Method
Cut the text in other people’s papers into pictures and put them in your own paper. Because CNKI's duplication checking system can currently only check text, but not pictures and tables, it can avoid duplication checking.
Advantages: More convenient and faster than Google Translate.
Disadvantages: If you use it smoothly, it is easy for the entire page to be filled with pictures, which will affect the word count of the entire paper.
Method 5: Insert document method
Insert the text from certain references into the paper in the form of a word document.
Advantages: This method is better than method 4, because this method can also be re-edited in the inserted document in the future, while the image conversion method is not easy to modify later.
Disadvantages: Not discovered yet.
Method 6: Insert spaces method
Insert spaces between all the words in the article, and then adjust the spacing between spaces and words to the minimum. Because the basis for duplication checking is based on words, and spaces cut off words, the duplication checking system will naturally be skipped.
Advantages: Based on the principle of duplication checking system, it has high reliability.
Disadvantages: The workload is huge. You can consider completing it through macros, but the preparation of macros needs to be studied.
Method 7: Use your own original method to write your own paper. When writing, either copy and paste the original text or add citations correctly.
Advantages: Basically, you will never worry about failing the duplication check, no matter how low the threshold of the duplication check system is adjusted.
Disadvantages: If we talk about advantages and disadvantages, it is that after writing a graduation thesis, more brain cells may die.
4. Paper plagiarism checking websites and their use
There are many Chinese plagiarism checking websites commonly used on the Internet, such as CNKI, Xuekexing paper plagiarism checking, etc.
. 1. CNKI
(1) When checking for plagiarism, the yellow text is "citation" and the red article is "suspected of plagiarism".
(2) When checking for plagiarism, only the text part is checked, and "pictures", "mathtype edited formulas", and "word field codes" are not checked. It is recommended to use mathtype to edit formulas instead of the formula editor that comes with Word.
(3) The "table" edited by word and excel can be found. In some desperate situations, you can choose to put a screenshot of the table into the paper! The author has personally seen the coefficients compiled by a classmate, and found out that they are heavier than others. The data determines that the coefficients cannot be changed, and I want to cry without tears...
(4) Reference citations must also be counted. Repetitive rate! Therefore, when quoting other people's literature, it is best to rephrase it in your own words.
(5) Duplicate checking takes "chapter" as the basic unit. For example, "Cover", "Abstract", and "Introduction" will be treated as a separate chapter. Each chapter will produce a test result and indicate the repetition rate. Each chapter has a separate repetition rate, and there is an overall repetition rate for the entire text. When some schools stipulate whether a paper passes the plagiarism check, they not only require that the repetition rate of the full text cannot exceed a certain limit, but also require the repetition rate of each chapter.
(6) The duplication check is indeed based on "13 consecutive words that are repeated in other articles" as the basis for judgment, which is consistent with what some online authors said before. If you can change any sentence in the paper to be different from other articles by any 13 consecutive words, it will not be found.
(7) Books and textbooks are not available in the database. However, students who copy books need to be aware that the part you copied may have been copied by other articles, and it will be repeated during the test. This situation often occurs, especially some classic theories that have been used for hundreds of years. Someone must have written it! For more information, you can search for "Xuekexing Paper Plagiarism Check".
(8) Some content on the Internet is also in the CNKI database. For example: "Baidu Wenku", "Daoke Baba", "Doudin", "Interactive Encyclopedia", "Baidu Encyclopedia". When checking for plagiarism, I even encountered many strange websites, such as Shenma's "Oriental Fortune Network Blog" and "National People's Congress Economic Forum". So, be careful when choosing content online.
(9) Foreign language documents are less stored in Chinese databases. I encourage everyone to read more foreign literature, learn more about advanced foreign scientific knowledge and engineering technologies, translate them, and apply them to our country's socialist modernization papers!
(10) It is recommended that schools check it online at their own expense before checking for plagiarism. The inspection report will "mark red" the duplicated parts and revise them first.
(11) After checking and modifying, students should not take it lightly. Because here comes the most perverted and infuriating part of the plagiarism check: there is no "red mark" in the first plagiarism check, but "red mark" may appear in the second plagiarism check, saying that you have plagiarized. If you are willing to spend money, spend money to check again online until the repetition rate is lower than the school's required repetition rate.
In addition to CNKI, high-efficiency duplication checking and duplication reduction software can automatically modify language expressions and effectively reduce repetition rates. Xuekexing Duplication Checking Software is recommended by Xuejun to detect papers quickly, comprehensively and accurately, and it is also free software. .
