The identification criteria of plagiarism in master's thesis are mainly based on originality, citation norms and literature review. When determining whether there is plagiarism, we need to consider multiple factors comprehensively, and we can't judge by just one factor.

The results show that the identification criteria of plagiarism in master's thesis mainly include the following aspects:

First, originality. As a postgraduate thesis, master's thesis requires independent research ideas, methods and conclusions. Therefore, the content of the paper should be the author's own thoughts and achievements, rather than copying other people's research results. If you find a lot of similar or similar contents in the paper, there may be plagiarism.

Second, refer to the specification. When citing other people's research results, they should be cited according to academic norms, and the source should be indicated in the article. If there are quotations in the paper that are not marked with the source or are not standardized, there may be plagiarism.

Third, the repeated inspection of documents. Document duplication checking is one of the important means to judge whether there is plagiarism in a paper. By comparing the paper with the existing literature, we can find the similarities or similarities between the paper and other literature. If you find that there are a lot of similar or identical contents in the paper with other documents, there may be plagiarism.

To sum up, judging whether there is plagiarism in master's thesis requires comprehensive consideration of many factors, and can't be judged by just one factor. When writing a paper, we should pay attention to originality, standardize citation, check the repetition of literature and avoid plagiarism.
