You can quote some, but it will take up the citation rate. Step 1: The first draft usually has a high repetition rate (unless you are a great god who writes word for word). You can use Wanfang and papertest to test it and then modify it sentence by sentence. This system is sentence-by-sentence detection, which means that any sentence you copy will be detected. This detection algorithm is strict, and the analysis from the point of view of program is simple. So everything sold online is very cheap. After measuring 30 thousand words, it feels good and cheap. (Note: 1 does not include your last graduate brother's big thesis, so be sure to pay attention to revision. Two people suggested that if the school takes the Wanfang exam, it should not take the VIP exam. Make a copy of the electronic version of the paper first and save one. According to the test results, in a backup test paper, the duplicate parts can be deleted first, and those that cannot be deleted can be modified within 15 words. It is best to add and subtract characters, and changing the order is of little use. Some references have been deleted. If they cannot be deleted, you can modify them first. English documents can be changed from 15 characters to one word. Hand in the revised ones and check the system again. The saved original paper is slightly modified and submitted to the paper version. That system is very troublesome. You can add many documents that you haven't seen or applied for. It can be seen that China people copy from each other, but in order to ensure the integrity and accuracy of the paper, don't change it at will. The paper version submitted must be considered, and it will not pass the test system after general inspection, so don't worry about the paper version. Step 2: After modification, the repetition rate is greatly reduced. At this time, you can use HowNet to check. HowNet duplicate checking system is a piece-by-piece detection, which is more intelligent. After testing, it is basically to make some local changes. Finally, I checked with HowNet, and it was 4% online, but it was simply changed, and it was 1.5% at school. Note: remember, the most taboo is to change the sentences of the paper illogical and illogical in order to check the duplicate, so that you can't escape the teacher. Haha, come on! About the relevant spot check regulations of HowNet: If there are any regulations, you can make the first revision and reply after the revision is passed. If you fail the second time, you are finished. You must hand in your paper or design within the next four months. This is based on 30% plagiarism. If you plagiarize more than 50%, you will have to hand in your paper or design within the next 4 months. 1. Undergraduate graduation design (thesis) identified as plagiarism, including the total number of words repeated with other people's existing papers and works, is between 30% and 50% (including 50%), which needs to be revised by myself. After revision, you can take part in the college defense only after passing the test again. Those who are still unqualified after the second interview are deemed to have graduated. You must submit the rewritten graduation design (thesis) after 3 months, and then take part in the defense after passing it. 2. Undergraduate graduation design (thesis) identified as plagiarism, if the total number of words repeated with other people's existing papers and works exceeds 50%, will be directly treated as graduation. You must submit the rewritten graduation design (thesis) after 4 months, and then take part in the defense after passing it. Detailed description of hownet system calculation standard: 1. After reading the introduction of this system, I have a question. This system is good for text copy recognition, but what about other aspects, such as data and charts? Isn't it useless to detect it? Among all kinds of academic misconduct, plagiarism is the most common and serious. At present, the detection system has reached a high level. The detection of plagiarism and tampering of charts, formulas and data is currently under development and has made great progress. You are welcome to continue to pay attention to the progress of this detection system and put forward more critical and constructive opinions and suggestions. 2. According to this system, less than 39% is displayed in yellow, so does it mean that it is within the tolerable limit? Recently, I read the news that the national social science fund project of a teacher in Shanghai University was cancelled because two papers he published were plagiarized, accounting for 25% and 30% respectively. Please specify what the warning line is. Percentage only describes the proportion of overlapping words in the detected documents, and does not refer to the plagiarism of the documents. It can only be said that the greater the percentage, the more overlapping words, and the greater the possibility of plagiarism. Whether it is plagiarism or not and the severity of plagiarism need to be decided by experts after review. 3. How to prevent the academic misconduct detection system of dissertations from becoming a platform for personal revenge? This is something we are seriously considering. At present, this detection system is only used by users at the institutional level. We have established a strict management process. At the same time, technically, we have also taken various measures to prevent malicious acts as much as possible, including a series of strict identity authentication and login. 4. The minimum detection unit is one sentence, so you can't detect one or two words in each sentence? We also deal with sentences accordingly, and have an algorithm of sentence similarity. It is not the same sentence that is judged to be the same. Sentences have sentence-level similarity algorithms, and paragraphs have paragraph-level similarity algorithms. Calculating whether a document or paragraph is similar to other documents is based on this. 5. If the original word is taken from relevant books, but the word has been copied from relevant documents in the database, that is to say, the previous article also took the same word from relevant books, but the words marked in my paper are from relevant books, is this academic plagiarism? The detection system can't draw a conclusion, whether it is plagiarism or not, and finally there is manual review. So if it is the situation you describe, experts will make corresponding judgments. Our system only provides all kinds of clues and basis, so that people can quickly grasp the information of test literature. 6. The authority of HowNet detection system? The detection system of academic misconduct documents has not reached a conclusion, that is, the detection system does not characterize the detection documents, but only shows the similarities between the detection documents and other published documents and lists objective facts, and whether such detection documents belong to academic misconduct needs the final examination and confirmation of experts. I found an article on the Internet-"Algorithm for Checking Duplicate Papers and Modifying Raiders". After you read it carefully, it will be helpful. At present, the detection system of master's and doctoral dissertations in colleges and universities is developed by HowNet. But the specific algorithm and judgment standard of the software were not clear before. This paper was obtained from the insiders of HowNet, and revealed the algorithm of the anti-plagiarism detection system of HowNet, how to judge the plagiarism of the paper and how to modify it to pass the cheater. Send it out to benefit everyone. 1. Requirements for format: the format of the whole paper 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. Will not affect the passage. The algorithm of the system is complex, and there may be small plagiarism that was not detected for the first time after each modification (two years of practical experience has proved that small plagiarism will not exceed 200 words, and the plagiarism rate will be greatly reduced after the second modification). 2. The comparative databases are: China Academic Journals Online Publishing Database, China Doctoral Dissertation Full-text Database/China Excellent Master Dissertation Full-text Database, China Important Conference Papers Full-text Database, China Important Newspapers Full-text Database and China Patent Full-text Database. HowNet database is the national designated thesis detection and comparison database, and the national designated university thesis detection system is HowNet dissertation detection system. This system is the most effective and extensive official detection system at present, and all universities are HowNet detection systems, which are implemented by the Ministry of Education for the fairness of academic misconduct in the whole country. 3. After the paper is uploaded, the system will automatically detect the chapter information of the paper. If the directory settings of your school meet the built-in chapter judgment conditions of HowNet system, the system will test the results by chapter, otherwise it will segment the results. Segments or chapters mainly deal with thresholds in 4. Honesty paper reminds us that whether it is divided into chapters or sections, it can be consistent with the school. 4. Can the quoted ones be detected? Some students asked: "I clearly quoted other people's paragraphs or sentences, why didn't I notice?" Some students also asked, "My quotations are all marked with the source, so why did I copy them?" First of all, whether a citation belongs to plagiarism has nothing to do with marking the source, and whether the citation can be detected has nothing to do with the accuracy of the system. These all depend on the threshold of the system. China HowNet has set a threshold for the sensitivity of this detection system, which is 3%. Calculated by the number of words in a paragraph (or chapter), plagiarism or citation of less than 3% of a single document cannot be detected, which is common in large clauses or small concepts. For example, if the detection paragraph 1 (chapter 1) has 10000 words, if A document is cited, it will not be detected within 300 words (10000 times 3%=300). If more than 300 words are quoted from the B document, the plagiarism of the B document distributed in the first chapter will be marked in red, no matter where it is located in the first chapter, even if it is interrupted into a sentence, as long as it exceeds 20 words, it will be marked. In fact, here also tells the students a modification method, that is, don't choose an article to quote from paragraph plagiarism, choose as many documents as possible, and intercept a few words from an article, so that it won't be found out. ② Some students asked why the quotation was plagiarized, mainly because of the threshold of HowNet. If it is higher than 3%, it is plagiarism, that is, the critical value of plagiarism is between 3%. Once it exceeds the standard, even if the quotation is marked, it will not help. So please pay attention to the students. For example, the first chapter of a paper has 5000 words, so only documents with less than 150 words can be quoted in the first chapter, otherwise it will be considered plagiarism by the system. The second chapter is 4000 words, and only documents below 120 words can be quoted, otherwise it will be considered plagiarism by the system. The third chapter is 8000 words, and the fourth chapter is 7000 words, which are below 240 words and below 2 10 words respectively, and so on. To sum up, the calculation method of citation exceeding the standard is calculated by chapter, just like the calculation method of plagiarism. 5. How can the system copy a sentence? How to detect plagiarism in papers? The condition of hownet paper detection is that the similarity or plagiarism in units of more than 20 words will be marked in red, but the prerequisite in 4 must be met: that is, the sum of a document you quoted or plagiarized should reach 3% in each detected paragraph (chapter). 6. In addition to the modification methods mentioned in 3, there are also changes in words, sentences and description methods (changing the original sentence into inverted sentence, passive sentence, active sentence, etc.). ), disrupt paragraph order, delete keywords, key sentences, etc. Practice has proved that the combination of the above methods can effectively reduce the replication rate and ensure the smooth passage. Generally speaking, we need to keep different from the original sentence on the premise of ensuring the smoothness of the revised sentence. Example 1: For example, the following sentence: Overheating in overheating fault is different from heating in normal operation of transformer. During normal operation, its heating source comes from winding and iron core, that is, copper loss and iron loss, while the overheating fault of transformer is due to the accelerated deterioration of insulation caused by effective thermal stress, which has a medium level of energy density. Almost marked in red, indicating that there is overlap with similar documents, and the similarity is high. Through the combination of the above methods, this sentence can be changed to: overheating in overheating fault is easily confused with heating in normal operation of transformer, which is caused by copper loss and iron loss in its winding and core, and is heating in normal operation, while overheating fault of transformer is accelerated insulation deterioration caused by effective thermal stress. The 300 words mentioned here are approximate values, not critical values. The fewer the number of references, the less likely it is to be detected. ② The updated CNKI academic misconduct detection system has adjusted this threshold to 3%, compared with 5% in the past, which means that the detection system has stricter requirements for citation, but it is not difficult to use the method we mentioned later. Has a medium level of capacity density. This modification can almost reduce the plagiarism rate by half. Example 2: Look at the following example: 3.7. 1.2 When a small amount of fibers are put into clear water of transparent glass and stirred, it can be intuitively found that the fibers are scattered in a three-dimensional suspension, and the changes are not great for a long time, indicating that the synthetic fibers are of good quality; Inferior fibers may be scattered after mixing, but they will soon float into a flocculent layer. In the actual preparation process of concrete, inferior fibers are not easy to disperse evenly. This paragraph is completely marked in red, and there is only one way to modify it, which is to disrupt the order and reorganize it. 3.7. 1.2 Put a small amount of fiber into a transparent container filled with clear water, and observe the changes of fiber while stirring. If the synthetic fiber is of good quality, you can intuitively see that the fiber is dispersed in a three-dimensional suspension state, and its position will not change obviously with the passage of time; If the synthetic fiber is of poor quality, the fiber may disperse during the mixing process and easily float to form a flocculent layer. In the actual preparation process of concrete, inferior fibers are not easy to disperse evenly. Example 3: Next sentence: Make overall consideration of the design change requirements put forward by the construction unit or the owner, determine its necessity, and comprehensively analyze the impact of design change on the construction period and cost. If it is really necessary to change, the construction scheme should be adjusted to minimize the adverse impact on the project. It is revised as: once the construction unit or owner puts forward the design change request, it must make overall consideration and investigate the necessity of the change. At the same time, it is necessary to conduct a comprehensive and scientific analysis of the possible impact of design changes on the construction period and cost, and adjust the construction plan when necessary to minimize the adverse impact on the project.
