In fact, the spot check of papers has only appeared in recent years, and it has not happened before. Interested students can refer to the document Sampling Methods for Doctoral and Master's Dissertations issued by the Ministry of Education 14 (degree [2014] No.5). It is this document that makes the sampling of papers in the second year after graduation a routine work. If it is drawn, there are generally two processes, paper review+peer review by three experts. Peer review is related to experts' subjective judgment and is not easy to control. However, the re-examination of the paper exists objectively, and it can be run directly through the HowNet system. Once the plagiarism ratio is too high or two peer review experts fail, the paper will be directly classified as a problem paper, which will have an impact on the degree-granting units and individuals. As for the impact, it depends on how big the paper problem is.

I manually check hundreds of master's and doctoral theses every year, and many students will ask about the sampling situation in the second year; Generally speaking, I suggest three points. First, try not to give big papers to younger brothers and sisters as small papers to prevent embarrassment when sampling in the second year; Secondly, I used to pay attention to the safety of the paper, because if the paper was plagiarized, there was no system to find it in the past, and you simply couldn't figure out whether your paper was sold by fishing. Thirdly, for master's thesis, even if the school doesn't need to use HowNet to check the duplicate (of course, there are few such schools), individuals who are afraid of sampling will finally use HowNet to check the duplicate, because sampling uses HowNet to check the duplicate.

Besides, the Ministry of Education originally issued a sampling inspection policy to control the quality of papers, but unexpectedly found many plagiarism cases. You can do it yourself. Is there more and more plagiarism in graduate thesis in recent years? This is all because of sampling and checking the weight of the network. How did the plagiarism of that paper come from? It must be that I caught a lot of classmates when I checked the weight at sixes and sevens the year before last, and let everyone know the whole link. Finally, I would like to express some personal opinions. I think the 5% sampling by the Ministry of Education is still too little. I think the master's thesis should be thoroughly examined in the second year, so that there is nothing to hide about the fishing, trading and plagiarism of the thesis, and everyone has a clear master's thesis environment.
