  2. 2. h-Index h-index developed in 2005 by Jorge Hirsch, University of California in San Diego Attempts to quantify productivity and apparent scientific impact of a scientist. “A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each”. For example, an h-index of 20 means that the researcher has 20 papers each of which has been cited 20 or more times Calculated by Scopus, WoS, Google Scholar, but only for those papers within the database 17/11/13 www.rba.co.uk 2
  3. 3. g-Index g-index - distribution of citations received by a given researcher's publications Devised by Leo Egghe in 2006 “Given a set of articles ranked in decreasing order of the number of citations that they received, the g-index is the (unique) largest number such that the top g articles received (together) at least g2 citations.” g-index - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/G-index 17/11/13 www.rba.co.uk 3
  4. 4. Other indices i10 Index i10-index is the number of publications with at least 10 citations e-Index PLOS ONE: The e-Index, Complementing the h-Index for Excess Citations http://www.plosone.org/article/info:doi %2F10.1371%2Fjournal.pone.0005429 17/11/13 www.rba.co.uk 4

  6. 6. What if the author hasn’t claimed their papers Various programs, browser extensions and add-ons that can be used to calculate citation indices May be browser specific and have to download programs to your computer The programs cannot differentiate between authors with the same name – papers have to be manually removed from the list – not always obvious which papers belong to which authors 17/11/13 www.rba.co.uk 6
