Every school is different, and the full-text repetition rate is below 30% (while some schools have undergraduate courses of 20%). There should be no requirement for the repetition rate of each chapter. Every school will make detailed rules, and the school will also give them places to check the repetition rate-basically China HowNet. Call the teacher specifically. Every school in every field has different requirements.

Graduation thesis duplicate checking includes:

1, paragraphs and format of the paper

Paper detection is basically the whole article upload. After uploading, the paper detection software first divides it, and the final manuscript format has a great influence on the plagiarism rate.

The division of different paragraphs may cause small paragraphs of dozens of words not to be found. So we can reduce the plagiarism rate by dividing more small paragraphs.

2. Database database

Paper detection mostly aims at matching published graduation papers, periodical papers and conference papers, and some databases also contain some articles on the Internet.

3, chapter conversion

Many students changed the order of chapters, or extracted different articles from different articles, which had little effect on the results of plagiarism detection.

4. Mark references

Reference symbols are added to the paper, but in the plagiarism detection software, they are all handled uniformly. The threshold of software is generally set to 1%. For example, an article is 5000 words, and 1% of the article is 50 words. If more than 50 words are plagiarism, even if references are added, it is also plagiarism.

5. Word number matching

Paper plagiarism detection system is strict, as long as more than 20 units of text match, it is considered plagiarism, but the premise is to meet the fourth point, the labeling of references.
