Some of them are relatively loose, about 20%-30%, and those who exceed them need the signature of the tutor; Others require that the repetition rate of papers be controlled within 5%- 10%. Different academic degrees or different schools have different requirements for the repetition rate of papers: the repetition rate of undergraduate papers &; lt； 30% can apply for defense; & amplt； 15% can apply for excellent papers; & amplt； 10% can apply for excellent papers at the school level; & ampgt； 25% have the opportunity to revise it for no more than 5 days, and the revised test failed to pass the extension defense. Repetition rate of master's thesis &; lt； 20% can directly apply for defense; & amplt； 40% have the opportunity to modify it for no more than 2 days, and the modification test fails to pass the extension defense; & ampgt； 40% directly extended for half a year. Repetition rate of doctoral thesis &; lt； 10% can apply for defense; & ampgt； 20% is directly extended for six months to one year. It should be noted that different duplicate checking systems are adopted by schools, and the results of repetition rate are also different. This is because the search scope of each system is different, that is to say, their databases contain different resources. If the duplicate checking system you use only contains the documents you refer to, then your repetition rate will naturally be higher than those that are not included.
But the database is only one aspect, and the high repetition rate does not necessarily prove that the detection system is more accurate, because there is still an algorithm problem. Do you think that if you change a few words, add a few words and rearrange the sentences, the system will not detect them? Take papertime paper duplicate checking system as an example, because it uses semantic recognition technology to compare, as long as the similarity of two sentences reaches 50%, it is considered to be similar. The orange font of similar paragraph indicates that this paragraph is slightly plagiarized and can be modified as needed. The red font of similar paragraphs indicates that the paragraph is seriously plagiarized and needs to be completely revised. No matter what duplicate checking system is adopted by the school, it is very necessary to check the papers before the defense. The detection service provided by papertime paper duplicate checking system has a free word experience, and a detection report will be provided after the detection is completed. If you want to get more accurate results, you can also use the "self-built database" function to upload the cited documents directly, and the system will give priority to the documents you upload. Are you afraid that the results are not accurate enough?
