Checking the duplicate of graduation thesis is an essential step in the thesis, although in the process of writing graduation thesis, every paragraph can be typed by keyboard, and the quoted contents are marked.

Although this similarity is unintentional, the duplicate checking system can find these duplicate contents, which leads to a high repetition rate of the paper and cannot be replied.

Almost every year when college students graduate, one of the problems they will encounter is writing papers.

Writing a high-quality paper requires a lot of energy and a lot of literature, and it takes several months to complete. After the completion, in addition to the research content defined by the tutor, the format of the graduation thesis needs to be revised.

These are the benefits brought by the paper duplicate checking system to the academic community, and the paper duplicate checking has brought some light to the academic community. However, duplicate checking simply ensures that the text of the paper will not be copied, and the data and academic achievements of the paper cannot be substantially maintained.
