It is a fact that many researchers love to publish their research works in journals that have impact factor. The higher the impact factor, the tougher and stricter the acceptance of any research draft paper. Some of these researchers will publish their work in Scopus indexed journals. Publishing in Scopus indexed journal is still better than having no other reputable publications. Some of the researchers also wonder how Journal Impact Factor or sci impact factor is calculated.
Journal Impact Factor is actually from Journal Citation Report (JCR). It is a product of Thomson ISI (Institute for Scientific Information). JCR provides quantitative tools for evaluating and assessing journals. The impact factor is one of the ways of measurement of a journal. It is a measure of the frequency with which the “average article” in a journal has been cited in a given period of time.
How journal impact factor is calculated?
The impact factor for a journal is calculated based on a three-year period, and can be considered to be the average number of times published papers are cited up to two years after publication. For example, the impact factor 2010 for a journal would be calculated as follows:
A = the number of times articles published in 2008-9 were cited in indexed journals during 2010
B = the number of articles, reviews, proceedings or notes published in 2008-2009
impact factor 2010 = A/B
(note that the impact factor 2009 will be actually published in 2010, because it could not be calculated until all of the 2009 publications had been received. Impact factor 2010 will be published in 2011)
