1. The principle of duplicate checking
1. Hownet dissertations are uploaded as a whole, and the format may have an impact on the detection results. It is necessary to submit the final submission format for detection to minimize the impact, which may not be detected for a few tens of pieces. Papers with more than 3, characters can be ignored.
The comparison databases are: China Academic Journals Online Publishing Database, China Doctoral Dissertation Full-text Database/China Excellent Master Dissertation Full-text Database, National Important Conference Papers Full-text Database, China Important Newspapers Full-text Database, China Patent Full-text Database, Personal Comparison Database and other comparison databases. Some books are not in HowNet Library and cannot be detected.
2. After uploading the paper, the system will automatically detect the chapter information of the paper. If there is automatically generated directory information, the system will detect the paper by chapter, otherwise it will automatically detect it by section.
3. It is normal for some students to report that they clearly quoted or copied paragraphs or sentences from other documents in their paragraphs, and why they were not detected. 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 there are 1, words in paragraph 1, a single document with less than 5 words will not be detected. In fact, here also tells the students a modified method, that is, never choose an article to quote from paragraph plagiarism, choose as many documents as possible, and intercept a few words from one, so that it will not be detected.
4. How can plagiarism in a paper be detected? The condition of hownet paper detection is that 13 consecutive words that are similar or plagiarized 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, seven ways to quickly check the duplicate of papers
method 1: translation of foreign documents
consult foreign documents in the research field, especially those in high-level journals, such as Science, Nature, WaterRes, etc., and translate the theoretical explanations into Chinese and put them in your own papers.
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. 2. Reading foreign literature can improve one's English level and broaden one's professional field of vision.
Disadvantages: Students with poor English, especially those with poor professional English, are hard to implement.
method 2: change the wording method
rewrite the words in other people's papers according to the meaning, or change the sentence structure, change the active and passive voice, or change the keywords, or increase or decrease. Of course, if it is a classic famous sentence, it should be quoted in the classic way.
Advantages: 1. After the text is modified, according to HowNet program and algorithm, as long as there is no repetition of 13 consecutive words and keywords, it will not be marked red. 2. 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 correction is time-consuming and laborious.
Method 3: Translation with translation tools such as google
Translate the words in other people's papers into English with google, and then translate them back, and the sentence pattern and structure will change, and then correct the mistakes yourself, so that you can successfully avoid duplicate checking.
advantages: it is convenient and quick, and can be modified from section to section.
Disadvantages: Sometimes it needs to be translated several times, and it must be translated from Chinese into English, then into Algerian, and then into Chinese.
method 4: transform the picture method
cut the words in other people's papers into pictures and put them in your own papers. Because at present, the duplicate checking system of HowNet can only check words, but not pictures and tables, so it can avoid duplicate checking.
advantages: it is more convenient and faster than google translation.
Disadvantages: If you use it conveniently, it is easy to see pictures all over the page, which will affect the word count of the whole paper.
method 5: insert document method
insert some referenced 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, while the image conversion method is not convenient for further modification.
disadvantages: I haven't found them yet.
method 6: insert spaces
insert spaces between all the words in the article, and then adjust the space between the empty words to the minimum. Because the basis of duplicate checking is based on words, spaces cut off 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, and the course can be completed through macros, but the compilation of macros needs to be studied.
Method 7: Make your own original method
Write your own paper, or don't copy and paste the original text when writing; Either add a quote correctly.
advantages: basically, you will never worry about failing the duplicate checking, even if the threshold of the duplicate checking system is adjusted lower.
Disadvantages: If there are advantages and disadvantages, it is that after writing a graduation thesis, more brain cells may die. Ha ha. . .
