After the "Joint Comparison Database of Academic Papers" and "Joint Comparison Database of College Students' Papers" are upgraded, the duplicate-checked papers will be put into the duplicate-checking database after the second year as the source of duplicate-checking comparison.

Generally, the time is in the second half of the second year, so it will not affect the duplicate check in that year. If the duplicate check is made again in the second year, the real author's name must be filled in. HowNet will remove my published literature and give an index to remove the copy ratio of my published literature.

HowNet's "monopoly of academic resources" and "overpriced" have become the focus of attention and discussion.

HowNet has strong bargaining power because of its strength.

Even Peking University has encountered a "price crisis", but think about the situation in other universities.

China Knowledge Network was established in response to the concept of "National Knowledge Infrastructure" put forward by the World Bank, and it is a part of "China Knowledge Infrastructure Project". Its fundamental purpose is to provide data resources and tools for knowledge production and theoretical innovation, which is very inclusive and public welfare. But now it seems that infrastructure overemphasizes its profitability.
