The paper duplicate checking system of HowNet has a threshold. There will be errors when the same paper is tested at the same time. There are also errors in the results of the changes in the structure and content of the paper, but the overall difference will not be too great.
Senior's thesis can't escape the eyes of HowNet's duplicate checking system. Because CNKI's PMLC detection system has a "joint comparison database of college students' papers" and CNKI's VIP5.3 detection system has added a "joint comparison database of academic papers", we try to avoid quoting other people's papers when writing papers.
Why can't the paper duplicate checking system of HowNet detect plagiarism? First of all, the content of plagiarism is very short, which can avoid the repetition of HowNet; In fact, if the content you copied is not in the HowNet system, you can't find it. Therefore, some ancient books and foreign literature knowledge networks may not be detected. It is possible that multiple articles are picked up and pieced together, and no duplication will be detected.
Why is the repetition rate of quoted content still so high? That's because the total plagiarism ratio contains two values: citation plagiarism and plagiarism. Judging from the final test results, citation has no effect on the total score, so don't pay too much attention to the citation part, unless the school has this requirement, depending on the repetition rate after removing the citation.
The above is my summary of the latest duplicate checking rules of HowNet papers. The update and increase of the literature comparison database make the duplicate checking rules more rigorous, and many papers that were not included before were not included. Judging from the collection time, if it's the same paper, HowNet hasn't come to collect it yet, so you can refer to it, as long as the thesis tutor doesn't look for it, it's no problem.
