The journal impact factor is calculated according to the number of papers published by the journal in the previous two years cited by other journals. The higher the value, the greater the influence of the journal in academic circles. IF value is usually used to evaluate the importance of a journal and its contribution to the research in a specific field, but it has also been controversial and criticized.
As an academic evaluation index, if value is often used to measure the academic quality and research level of journals. Journals with high if value often represent that the papers published in this journal are widely recognized and cited, which has a positive impact on the research in related fields. At the same time, a higher if value can also bring greater influence and reputation to journals and attract more outstanding researchers to contribute to them.
Specifically, the if value reflects the citation frequency of a journal in academic circles, that is, the number of times the papers published in this journal are cited by other scholars. This index is calculated by dividing the total number of citations of articles published in the first two years of the journal by the total number of articles published in the first two years of the journal, and the result is the impact factor of the journal. For example, a journal published 100 articles in 20 19 and 2020 * *, and these articles were cited 1000 times, then the impact factor of the journal is 10.
