Paper duplication detection is an academic misconduct detection service. By comparing articles with documents in the database, we can check whether there are academic misconduct such as plagiarism. Generally speaking, the similarity detection of undergraduate graduation thesis generally includes the following parts:

1 Introduction: It mainly introduces the research background, purpose and significance. In the process of duplicate checking, the introduction part is usually not the key detection object, because the introduction part is often the basis and premise of academic research, and some general research backgrounds and purposes may have high similarity.

2. Literature review: It mainly combs and summarizes the existing related research. In the process of duplicate checking, the literature review is often the key detection object, because the academic community has higher requirements for literature review, requiring students to accurately understand and summarize the previous research results and express them in their own language. If there is a lot of plagiarism in literature review, it is obvious academic misconduct.

Text part: If the text duplication checking system identifies it, it is plagiarism, and it is not allowed to enter the defense link. Generally speaking, the text of the paper is some very common sentences, such as noun explanation, noun concept principle and so on. This kind of statement is generally used in headlines or other statements that will not change significantly.

4 References: Because the duplicate checking system of the school requires a high number of references for students, if students have too many references, the duplicate checking result will be higher. This also leads many students to pay too much attention to references when checking duplicates.
