You may not be able to distinguish many concepts when you first publish a paper, but before that, you need to know what the impact factor is?
Impact factor: It was proposed by Dr. Eugene Garfield, the former director of the Institute of Scientific and Technological Information (ISI) in 1963, and has become an internationally accepted journal evaluation index. The higher the impact factor of a journal, the stronger its academic influence.
Impact factor (IF) = (total number of citations of papers published in a journal in the previous two years) / (total number of papers published in the journal in the previous two years)
At present, Clarivate Analytics' JCR, WOS and the "Journal Division Table of Chinese Academy of Sciences Documentation and Information Center" all use the impact factor index to evaluate journals.
What do "Comprehensive Impact Factor" and "Composite Impact Factor" mean? Briefly:
1. Comprehensive impact factor: The comprehensive impact factor mainly refers to the integration of arts and sciences. It is calculated based on the comprehensive statistical source documents of scientific and technological periodicals and humanities and social science periodicals. The ratio of the total number of citations to the total number of citable documents published by the journal in the previous two years is calculated by compounding the number of citations of master's and doctoral theses, conference papers, and journals, but the comprehensive calculation only includes the number of citations of journals.
2. Composite impact factor: Calculated using journals, dissertations, and conference papers as composite statistical source documents, the total number of citations of citable documents published by the evaluated journal in the previous two years in the statistical year is equal to the total number of citations published by the journal in the previous two years. The ratio of the total number of citable documents.
The above explanation is too complicated. In short, when calculating two different impact factors (comprehensive impact factor and compound impact factor) of the same journal, it is equivalent to the same denominator (that is, the total number of citable articles published by the journal in the previous two years) , but the numerators are different. The numerator of the comprehensive impact factor is the total citation frequency of the documents published in the journal in journal papers, and the numerator of the composite impact factor is the number of citations of the documents published in the journal in dissertations, conference papers, and journal papers. Total Citations.
When we look at journal papers, we will look at both, but mainly look at the composite impact factor. Generally, the greater the impact factor, the greater its academic influence. Generally, the impact factor is about 5 points, and if it is higher than 10 points, it is very powerful.
