You must have heard of the impact factor of such and such a journal, but you may not have a very accurate and in-depth understanding of the concept of impact factor.
The SCI impact factor refers to the number of times a paper has been cited in a specific year (usually two years). Specifically, the impact factor is the total number of citations of an article in two years divided by the total number of citations of that article.
This ratio reflects how often the ** is cited by others, so we generally say that the impact factor of SCI can more or less reflect the influence of SCI in the academic field. The higher the impact factor, the higher the quality and importance of the **.
In fact, the calculation method of SCI impact factor is not difficult.
First of all, it is necessary to count the total number of citations of a certain article in two years, including the number of citations in various journals, conferences and other literature. Then, the total number of citations for that ** is counted, and this total number includes the number of times the ** has been cited by all other **. Finally, we divide these two values to get the impact factor of the **.
The SCI impact factor not only represents the first influence, in fact, this impact factor has many important roles in the academic field.
First of all, many academic reviews will use the impact factor to measure the qualityGenerally speaking, the higher the impact factor, the higher the quality of the **.
In addition, the impact factor will also be taken into account in the evaluation of scientific researchers。If the researcher publishes in a journal with a high impact factor, his academic impact is likely to be higher, because journals with higher impact factors tend to have greater impact.
Finally, the impact factor is also one of the important indicators to evaluate the academic level of scientific research institutions and scholars.
While the SCI is important, it has its limitations. First of all, the impact factor is only an indicator of recent performance, and it does not reflect the full quality and academic value of the company. Second, there is a risk that the impact factor will be manipulated, and some institutions or scholars may improve the impact factor through self-citation or cross-printing.
