Overview of duplicate checking of papers:
Because there are various paper similarity detection systems in the market, and some personal detection websites provide false paper detection results to students through fraud, the market is chaotic, which must be controlled. In fact, there are only three authoritative paper testing institutions in China: go check VIP/ HowNet CNKI/ Wanfang, which can be known by filing an 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. 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, one is that the pattern recognition technology is not advanced enough; Secondly, machine recognition is not smart enough in meaning recognition, but the experts of Gocheck paper detection have realized semantic recognition. The consistent view of the Explorer Pavilion is "strategic contempt, tactical importance" and "know yourself and know yourself, and win every battle".
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.
The databases for duplicate checking and comparison of papers include: online publishing database of academic journals in China, full-text database of doctoral dissertations in China/full-text database of excellent master's dissertations in China, full-text database of important national conferences, full-text database of important newspapers and periodicals in China, full-text database of patents in China, personal comparison database and other comparison databases. Some books are not in the HowNet Library and cannot be detected.
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.
3. 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. China Knowledge Network has set a threshold for the sensitivity of this detection system, and the threshold is 5%. In terms of paragraphs, plagiarism or quotations below 5% cannot be detected.
This situation is common in large clauses or small concepts. For example, if the detection paragraph 1 has 10000 words, a single document with less than 500 words will not be detected.
