JIIA Impact Factor

The Journal Impact Factor (JIF) is a measure reflecting the average number of citations to articles published in journals, books, patent document, thesis, project reports, news papers, conference/ seminar proceedings, documents published in internet, notes and any other approved documents. It is measure the relative importance of a journal within its field, with journals of higher journal impact factors deemed to be more important than those with lower ones.

How the Impact Factor was Calculated:
The calculation is based on a two-year period and involves dividing the number of times articles were cited by the number of articles that are citable.

Sample Calculation of 2018 IF of a journal:
A = the number of times articles published in 2016 and 2017 were cited by indexed journals during 2018.
B = the total number of “citable items” published in 2016 and 2017.

A/B = 2018 impact factor
