What are the skills and methods of quick overwinding in 2020?
Today, I will tell you about the principle and detection of paper duplicate checking, the skills and methods of paper duplicate checking, and the website and explanation of paper duplicate checking. 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 level.

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.

Second, the paper plagiarism detection algorithm

1. Paragraph and format of the file

Paper detection is basically the whole article upload. After uploading, the paper detection software first divides it, and the final manuscript format has a great influence on the plagiarism rate. The division of different paragraphs may cause small paragraphs of dozens of words not to be found. So we can reduce the plagiarism rate by dividing more small paragraphs.

2. Database database

Paper detection mostly aims at matching published graduation papers, periodical papers and conference papers, and some databases also contain some articles on the Internet. It is revealed here that many books are not in the testing database. Before, my friend extracted a lot of words from a research work and didn't find it out. It can be seen that this method is still effective.

3. Chapter conversion

Many students changed the order of chapters, or extracted different articles from different articles, which had little effect on the results of plagiarism detection. Therefore, plagiarism detection experts suggest that you should not think that copying a few or dozens of articles will pass.

4. Mark references

How to define quoting others' articles and copying others' articles in detection software? It's actually quite simple. In our paper, reference symbols are added, but in plagiarism detection software. All these are viewed in a unified way. The threshold of software is generally set to 1%. For example, an article is 5000 words, and 1% of the article is 50 words. If more than 50 words are plagiarism, even if references are added, it is also plagiarism.

5. Word number matching

Paper plagiarism detection system is strict, as long as more than 20 units of text match, it is considered plagiarism, but the premise is to meet the fourth point, the labeling of references.

Three, seven ways to quickly check duplicate papers: one is the translation method of foreign documents.

Consult foreign literature in the research field, especially those in high-level journals, such as Science, Nature and Water Resources. And translate the theoretical explanation into Chinese and put it in your own paper.

Advantages: 1, everyone's language habits are different, and the translated Chinese is bound to be different. Therefore, even if the same paragraph is translated by different people, there will be no plagiarism. Reading foreign literature can improve your English and broaden your professional horizons.

Disadvantages: Students with poor English, especially those with poor professional English, are more difficult to implement.

Method 2: Change the wording method

Rewrite the words in other people's papers, or change the sentence structure, active voice and passive voice, or change keywords, or increase or decrease. Of course, if it is a classic sentence, it should be quoted in a classic way.

Advantages: 1 After the text is modified, according to HowNet program and algorithm, as long as there are no repeated 13 continuous words and keywords, it will not be marked red. I know every word and sentence of the paper like the palm of my hand, and I know it by heart, and I will be like a duck to water when I reply.

Disadvantages: word-for-word revision is time-consuming and laborious.

Method 3: Translate through translation tools such as e google.

Translate the words in other people's papers into English with google, and then translate them back, the sentence pattern and structure will change, and then you can successfully avoid duplicate checking by correcting your own mistakes.

Advantages: convenient and quick, and can be modified in large sections.

Disadvantages: Sometimes it needs to be translated several times, and it has to be translated from Chinese into English, then into Algerian, and then into Chinese.

Method 4: Transform picture method.

Cut the words in other people's papers into pictures and put them in your own papers. At present, the duplicate checking system of HowNet can only check words, not pictures and tables, so duplicate checking can be avoided.

Advantages: It is more convenient and faster than Google Translation.

Disadvantages: If it is convenient to use, it is easy to see that the whole page is full of pictures, which will affect the number of words in the whole paper.

Method 5: Insert document method

Insert some quoted words into the paper in the form of word documents.

Advantages: this method is even better than the fourth method, because it can be re-edited in the inserted document in the future, and the image conversion method is not convenient for further modification.

Disadvantages: not found yet.

Method 6: Insert space method

Insert spaces between all the words in the article, and then adjust the spacing between empty words to a minimum. Because the basis of duplicate checking is based on words, spaces truncate words and naturally skip the duplicate checking system.

Advantages: Based on the principle of duplicate checking system, it has high reliability.

Disadvantages: The workload is huge, which can be completed by macros, but the compilation of macros needs to be studied.

Method 7: write your own paper, or don't copy and paste the original text when writing; Please add the quotation correctly.

Advantages: Basically, you will never worry about not passing the duplicate check, even if the threshold of the duplicate check system is lowered.

Disadvantages: If there are advantages and disadvantages, it is that after writing the graduation thesis, more brain cells may die.

Four, the paper copy website and use

There are many Chinese duplicate checking methods commonly used on the Internet, such as HowNet and duplicate checking of academic papers.

. 1. hownet

(1) When checking duplicate, the yellow text is "quotation" and the red article is "suspected plagiarism".

(2) When duplicate checking, only the text part is checked, and "Graphics", "mathtype Editing Formula" and "word Field Code" are not checked. 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 also needs to calculate the repetition rate! Therefore, it is best to rewrite your own words when quoting other people's literature.

(5) Check the duplicate with "chapter" as the unit. For example, "cover", "abstract" and "introduction" will all be used as.

Separate chapters, each chapter gives 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) Duplicate checking 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, you can be sure that it and other articles are arbitrary.

13 has different lines, so it can't be found.

(7) There are no books and textbooks in the database. 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! For more information, you can search for "duplicate checking of academic papers".

(8) 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 checking 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.

(9) Foreign documents are rarely stored in Chinese databases. 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!

(10) 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.

(1 1) After testing and modification, students should not take it lightly. Because the most abnormal and infuriating part of checking weight comes: 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.

In addition to HowNet, efficient duplicate checking and weight reduction software automatically modifies the language expression, effectively reduces the repetition rate, takes the lead in learning duplicate checking software, and can detect papers quickly, comprehensively and accurately. It is also free software.
