Paper plagiarism is also called paper plagiarism. In the Reply on How to Identify Plagiarism (Quan Si [1999] No.6) sent by the Copyright Administration Department of the National Copyright Administration to a municipal copyright bureau, "plagiarism" is defined as "stealing other people's works or pieces of works for publication". From a practical point of view, plagiarism can basically be divided into two categories: one is "low-level plagiarism", that is, copying the contents of other people's works intact or slightly adjusted; The other is "advanced plagiarism", that is, by changing the type and expression of works, the original content in other people's works is stolen from you. In the trial practice, it is easy to identify "low-level plagiarism". By comparing the proportional data of overlapping content, we can make a general judgment. It is relatively difficult to identify "advanced plagiarism", and the criteria to judge whether it constitutes copyright infringement are: whether the similar part is original, whether it uses the main part or substantive part of others' thought expression, the proportion and importance of the similar part in the work, and the overall cognition of the relevant public to the work.
Plagiarism and plagiarism in the copyright law are the same concept (hereinafter referred to as plagiarism, for the sake of brevity), which means plagiarizing other people's works or pieces of works for their own use.
