The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
the number of times articles published in the journal during each of the most recent 10 years were cited by individual specific journals during the year (the twenty journals with the greatest number of citations are given) and several measures derived from these data for a given journal: its impact factor, immediacy index, etc.
The values for Nature journals lie well above the expected ca. 1:1 linear dependence because those journals contain a significant fraction of editorials. CiteScore was designed to compete with the two-year JCR impact factor, which is currently the most widely used journal metric. [7] [8] Their main differences are as follows: [9]
Higher SJR indicator values are meant to indicate greater journal prestige. SJR is developed by the Scimago Lab, [5] originated from a research group at the University of Granada. The SJR indicator is a variant of the eigenvector centrality measure used in network theory. Such measures establish the importance of a node in a network based on ...
The importance of journals can be measured by the average citation rate, [9] [6] the ratio of number of citations to number articles published within a given time period and in a given index, such as the journal impact factor or the citescore. It is used by academic institutions in decisions about academic tenure, promotion and hiring, and ...
While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. [ 4 ] [ 5 ] In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023.
