The criteria for determining core journals can be summarized as follows: first, the authority of the host institution; second, the authority of the author of the article; third, the citation rate of the article and the half-life of the document (the index for determining the novelty of the article content, the half-life of general scientific and technological documents is shorter, while the half-life of social science documents is longer).
To put it simply, core journals are the most important core journals, which are tracked and evaluated by academic circles through a set of scientific methods and classified and graded according to the theory of information science.
In the international scientific community, how to correctly evaluate the achievements of basic scientific research has attracted more and more attention. However, the number of scientific papers collected by SCI and SSCI is regarded as an important evaluation index to measure a country's basic scientific research level, scientific strength and the number of scientific papers.
