are various ways of measuring the impact and quantity of an
individual's research performance. All have advantages and
disadvantages. Some of the more common are listed below:
- h-index - "a scientist has an index of h if h of
his or her Np papers have at least h citations each and the other (Np -
h) papers have less than or equal to h citations each" (Hirsch, J.E. (2005). An index to quantify and individual's scientific output. Proceedings of the National Academy of Sciences, 102 (46), 16569-16572)
- i10-index - indicates the number of academic
publications and author has written that have at least 10 citations from
other sources. Introduced by Google Scholar
- g-index - a given set of articles ranked in decreasing order of the number such that the top g articles received [together] at least g 2 citations.
- e-index - is defined as the square root of the sum
of the 'excess' citations in the papers that contributed to the
h-index. It aims to address the number of 'excess' citations above and
beyond the h-index.
