1. Probably all graduate dissertations today will pass the "academic misconduct test" of China HowNet, even if they are not blindly judged in the end. Many colleges and universities have introduced paper polygraph to check the repetition of students' papers.

2. Because there are various paper similarity detection systems in the market, and some personal detection websites provide false paper detection results to students by cheating, which leads to market confusion, and this situation must be controlled.

In fact:

1. There are only the following 30,000 authoritative paper testing institutions in China, which can be known through filing and inquiry. The original intention of the academic misconduct detection system is actually very good, which can play a warning role for graduate students who are about to enter the scientific research field in China to some extent: put an end to plagiarism and study hard.

2. However, the so-called "everything in the world, where there is a spear, there must be a shield" philosophy, China HowNet's "academic misconduct detection system" is not perfect. There are two reasons. First, the technology of pattern recognition is not advanced enough.

Principle of duplicate checking:

1. hownet dissertations are tested as a whole article, and the format may have an impact on the test results. It is necessary to submit the final submission format for testing, so as to minimize the impact, and dozens of blocks may not be detected. Papers over 30,000 words can be ignored.

2. After the paper is uploaded, the system will automatically detect the chapter information of the paper. If there is automatically generated directory information, the system will detect the paper in sections, otherwise it will automatically detect the paper in sections. It is normal for some students to report that they explicitly quoted or copied paragraphs or sentences from other documents in their own paragraphs, and why they didn't detect them.
