In fact, your so-called plagiarism refers to the act of infringing on other people's intellectual achievements or copyrights, that is, when someone's works and published works can make ordinary people have the same impression in content, they can be judged as plagiarism (this is only my personal explanation, and whether it constitutes plagiarism depends on many factors). I'll give you several cases to judge plagiarism and plagiarism:

1. The act of "not giving corresponding recognition" to the sources of opinions, materials and terms under the following circumstances: "repeating other people's words or particularly appropriate words", "changing words to use other people's arguments and arguments" and "stating other people's opinions";

2. Overall plagiarism: plagiarism in overall argument, conception and framework;

3. Direct plagiarism: directly find chapters and sentences from other people's works, and plagiarize whole paragraphs and pages; In order to hide people's eyes and ears, at the same time, copy down the quotations and notes in the original text.

4. In the case of copying other people's words throughout, only a few words are marked, which has a serious misleading effect on readers;

5, change for the sake of change, slightly change a few irrelevant words or change a sentence pattern;

6. Misunderstanding of the concept of summary: The meaning of "summary" may be that the same or similar viewpoints come from different theorists, so it is necessary to summarize and integrate them to form a more universal analytical perspective. Plagiarism means accepting all the censored objects in order.

7. Jumping plagiarism: looking for chapters and sentences from the same source text, not completely following the writing order and discussion logic of the source text;

8. Plagiarism: Putting together sentences from different sources, regardless of the context of these sentences in the source text.
