What are the criteria for duplicate checking of papers?

In general, it is necessary to check the duplicate before publishing a paper, so what is the standard for checking the duplicate? Now let's talk about it in detail:

Duplicate checking is a matching process, based on sentences. If a sentence is repetitive, it is easy to judge the repetition. Take the duplicate checking software HowNet as an example: China HowNet CNKI dissertation detection system TMLC/VIP, whose operation mode is to input the electronic papers into the electronic database, and then the database will match according to all the existing electronic data of HowNet or the network. If the software detects that there are 65,438+03 identical words, it is considered to be the same.

Paper duplicate checking standard:

1. Among all kinds of academic misconduct, text repetition is the most common and serious. The duplicate checking percentage in the paper detection system 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. There is an algorithm for 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.

2. The paper duplication 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. For example, the condition of paper detection on HowNet 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 in each detection paragraph should reach 5%.
