There are generally only two places for the collection of undergraduate thesis, one is the database of our school, and the other is the database of HowNet. Students can access it in our school, but we can't access the database of HowNet, which is related to the internal database of HowNet.

HowNet includes plmc detection system, which is specially used to detect undergraduate thesis. The database is a "joint comparison database of college students' papers", that is, all papers detected by plmc detection system will be included. However, because there is no cooperation agreement with the relevant authors, it will not be publicly displayed, but will only be compared during testing.

China HowNet, founded in June 1999, is an academic platform of Tongfang shares controlled by China National Nuclear Corporation Capital Holdings Co., Ltd. HowNet is the concept of National Knowledge Infrastructure (NKI), which was put forward by the World Bank in June 1998.

CNKI project is an information construction project aimed at realizing the dissemination, enjoyment and value-added utilization of knowledge resources in the whole society. On May 20 19, the online learning platform of Scientific Research Integrity and Academic Norms was officially launched in China HowNet.
