The h-index

The h-index  is a method of measuring the productivity and impact of a researcher's work. It was developed in 2005 by Jorge Hirsch, a physicist at the University of California in San Diego.  Hirsch’s aim was to qualify the impact and quantity of an individual scientist’s research output.

The h index is defined as the largest number h for which at least h articles are cited h times each.  For example, if a researcher  has published 10 articles whose rank-ordered citation counts are {12, 7, 9, 3, 2, 1, 1, 0, 0, 0}, his/her  h = 3 because there are 3 articles cited at least 3 times each, but not 4 articles cited at least 4 times each.

Calculate your own h-index

    Adjusting the h-index for career stage

    The m quotient, or mq index, is used to adjust h to take into account career stage.  Specifically, mq is calculated as h divided by publishing age, or the number of years since one’s earliest article.  This adjustment to the h index can be especially useful when comparing individuals at different career stages.


    Tools Available at UML

Youcan  make your profile public or private but if you make it public, you can link to it from your own webpages.
    • Harzing’s Publish or Perish (POP)
      • Publish or Perish Searches Google Scholar.  After searching by your name, deselect from the list of articles retrieved those that you did not author.  Your h-index will appear at the top of the tool.
