This is a linguistic analysis of the papers published in Journal of the National Medical Association, as the keywords have been extracted to find the performance of articles containing specific keywords. The keywords are chosen based on the weight on them in an article, NOT simply if they appear in an article.This graph is similar to the first one but lists the keywords according to the number of citations they received.
How are inpact factors calculated?

extended IF also counts citations from books and conference papers. However, no patent, abstract, working papers, online documents, etc., are covered.
