Text similarity: calculate the text similarity by comparing the text in the paper with the text in other papers. Generally speaking, if the similarity of words exceeds a certain proportion, it will be considered plagiarism. This ratio varies according to the requirements of different schools or institutions.
Citation format: the citation part of the paper also needs to be marked and quoted according to the specification. If the quotation format is not standardized, or the content quoted exceeds a certain proportion, it will be considered plagiarism.
References: The reference part of the paper needs to list all the cited documents, and the format should be standardized. If the reference is incomplete or the format is not standardized, it will be considered plagiarism.
Originality: the paper requires originality, that is, the author should express his own views and opinions in the paper, and cannot completely copy the achievements of others. If the paper is not original enough, it will be considered plagiarism.
To sum up, the judgment basis of the paper through duplicate checking is mainly based on text similarity, citation format, references and originality. In order to check the repetition of papers, authors need to abide by academic norms and ensure that the text, quotations and references of papers meet the requirements.
