Impact of the FESE

1.Impact Factor (IF)
The Journal Impact Factor is defined as all citations to the journal in the current JCR year to items published in the previous two years, divided by the total number of scholarly items (these comprise articles, reviews, and proceedings papers) published in the journal in the previous two years. For example, the journal impact factor 2022 for a journal would be calculated as follows: 

A = the number of times articles published in 2020-2021 were cited in indexed journals during 2022
B = the number of articles, reviews, proceedings or notes published in 2020-2021

Impact Factor 2022 = A/B


2.5-year Impact Factor 
The 5-year journal Impact Factor is the average number of times articles from the journal published in the past five years have been cited in the JCR year. It is calculated by dividing the number of citations in the JCR year by the total number of articles published in the five previous years.

3.CiteScore
CiteScore is a way of measuring the citation impact of journals. It calculates the average number of citations received in a calendar year by all items published in that journal in the preceding three years. The calendar year to which a serial title's issues are assigned is determined by their cover dates, and not the dates that the serial issues were made available online. Different from IF, the scholarly items published in the previous 3 years were accounted. 

4.Source Normalized Impact per Paper (SNIP)
SNIP measures the average citation impact of the publications of a journal. It takes into account characteristics of the source's subject field, which is the set of documents citing that source. It is the ratio of a source's average citation count per paper and the citation potential of its subject field.

5.SCImago Journal Rank (SJR)
SJR is a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from.
