Scholarly Metrics for UVM Faculty

Traditional Journal Level Metrics

Journal Impact Factor

Journal Impact Factor (JIF) is a metric found in Journal Citation Reports - a part of the Web of Science Interface. 
Journal Impact Factor is:
  • The total number of citations in the past two years ÷ number of articles published by that journal in the past two years.  (Avg. # of times an article published in that journal has been cited).
  • There is a 2 year look-back.   2016 Impact Factors are based on data from 2015 & 2014.
  • Data is based on articles indexed in the Web of Science database.
  • SCImago also calculates this number and calls it "Cites / Doc 2yrs," based on the Scopus database

A short tutorial on how to find and use Journal Impact Factors can be found here:  XXX

H-Index (H5, H10)

H Index, or Hirsch Index is used heavily in Google Scholar Metrics.   H-index can be used to assess both journal publications and individual scholars.
(Hirsch) H-Index is:
  • The H-index of a publication or scholar is the largest number h such that at least h articles were cited at least h times each. 
    • As an example, let's say a scholar has published 6 articles in the past five years.  The first article was cited 17 times, the second article 10 times, the third 3 times, and the fourth, fifth, and sixth articles were only cited 1 time.  To find H-index, the scholar might ask him or herself, "Has one article been cited at least once?  Yes - continue.  Have two articles been cited at least twice?  Yes - continue.  Have three articles been cited at least three times?  Yes - continue.  Have four articles been cited four times?  NO - only three publications have been cited three or more times, so the author's H-index is 3.
    • A publication would undergo the same type of questioning to find H-index, "Does this publication have 60 articles that have been cited 60 times?  Yes, continue.   Does this publication have 61 articles that have been cited 61 times....."
    • The theory behind H-index is that it assesses impact based a continued high rate of citation.  A scholar cannot have a high H-index with one big article nor can they have a high H-index with lots of publications that get no notice.  That said, H-index is still susceptible to self-citation and other criticisms made of traditional impact factors.
  • H5 includes a 5 year look-back, H10 includes a 10 year look-back.
  • H Index data in Google Scholar is based on items indexed by Google Scholar.
  • Set up a Google Scholar profile in order to automatically calculate your own H-Index in Google.

SCImago Journal Rank

SCImago Journal Rank (SJR) can be found at:
SCImago Journal Rank is:
  • A complicated algorithm to assess not only the number of citations but the “prestige” of the journals issuing those citations.
  • SJR data is based on articles indexed in the Scopus database, a competitor to Web of Science.
  • SJR is similar to “EigenFactor” in ISI Journal Citation Reports
  • SCImago also calculates "Cites / Document  2yrs" which is similar to ISI's Journal Impact factor, but based on the Scopus database.
