The qualified repetition rate of undergraduate thesis cannot exceed 30%, and that of doctoral thesis is usually 20% to 15%. Usually, the duplicate checking rate of general journals is required to be 20%-30%, and the duplicate checking rate of core journals is required to be below 10%. From undergraduate thesis to doctoral thesis, the higher the degree level, the higher the repetition rate of the thesis, and the different repetition rates that cannot be exceeded for different purposes are also different.

The purpose of paper duplication checking is to detect the repetition rate of papers, that is, the degree of plagiarism. The higher the repetition rate, the more academic misconduct the paper involves, so the repetition rate is also the quality requirement of many journals and universities.

Paper body, original description, abstract, icon and formula description, references, appendices, experimental research results, conclusions, introduction, patents, documents, notes and various tables. During the graduation season, most colleges and universities will issue a notice explaining the specifications and duplicate checking of graduation thesis, and the school will uniformly issue the paper style and other contents.

Duplicate checking rate is also called repetition rate, plagiarism rate and similarity rate. These words all have the same meaning. The paper duplicate checking rate is the percentage result obtained by comparing the papers uploaded by everyone with the database in the duplicate checking system, which is calculated according to the algorithm of the duplicate checking system. This percentage result is the most intuitive embodiment of repeating other people's papers.

Significance of duplicate checking of papers

The significance of duplicate checking is to prevent students from academic misconduct when writing papers, which seriously affects academic innovation. The so-called paper duplication checking is to compare and detect the similarity between the submitted papers and the data in the system database through the paper detection system.

At present, it has become an important means to prevent academic misconduct and is widely used. To a certain extent, paper duplication checking has played a normative role in academic failure and put an end to many bad habits. On the other hand, the paper duplication checking system can also help us find the repetition in the paper correctly and make it easier for us to revise it.
