Definitions

 

Bibliometric analysis use data on numbers and authors of scientific publications and on articles and the citations therein (and in patents) to measure the “output” of individuals/research teams, institutions, and countries, to identify national and international networks, and to map the development of new (multi-disciplinary) fields of science and technology.

Altmetrics  (Galliga, F. & Dyas-Correia, S.  2013.  Altmetrics: rethinking the way we measure.  Serials review, 39 (1): 56-61.)
Altmetrics are new measurements for the impact of scholarly content, based on how far and wide it travels through the social Web (like Twitter), social bookmarking (e.g. CiteULike) and collaboration tools (such as Mendeley) … What altmetrics hope to do is provide an alternative measure of impact, distinct from the Journal Impact Factor, which has been categorically misused and is unable to respond to the digital environment that scholarship takes place in today

H-Index
The index is based on the distribution of citations received by a given researcher's publications. Hirsch writes:

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.

To manually calculate your h-index, organize articles in descending order, based on the number of times they have been cited e.g.
An author has 8 papers that have been cited 33, 30, 20, 15, 7, 6, 5 and 4 times. This tells us that the author's h-index is 6.

h-index calculation

What does an h-index of 6 mean?

  • An h-index of 6 means that this author has published at least 6 papers that have each received at least 6 citations.


More context:

  • The first paper has been cited 33 times, and gives us a 1 (there is one paper that has been cited at least once).
  • The second paper has been cited 30 times, and gives us a 2 (there are two papers that have been cited at least twice).
  • The third paper gives us a 3 and all the way up to 6 with the sixth highest paper.
  • The final two papers have no effect in this case as they have been cited less than six times (Ireland, MacDonald & Stirling, 2013).
