Research Impact and Evaluation

Impact factors from JCRweb

The Impact Factor of a journal is based on the "citedness" of the articles in the journal.

It does not necessarily mean that the higher the impact factor, the more important the journal is. Impact factors should not be taken out of context.For example, a journal that publishes review articles gets a higher impact factor because of the nature of the publications. Or, a journal in a smaller field will never get a high impact factor because all the small number of publications.

How to find the impact factor of a journal?

You can find the impact factor of a journal in a database called JCRweb, also known as Journal Citation Reports.

After you access JCR, select the option, Search for a specific journal, and click on Submit. Enter the title or words from the title of the journal.

How is the impact factor of a journal calculated?

The Impact Factor of a journal is calculated in the following way:

S = number of articles published in the journal in the last two years, e.g. 2007 and 2008
R = number of citations in 2009 in all publications that indicate the journal from 2007 and 2008 as source

Journal Impact Factor = R/S
