Title: | A rationale for the Hirsch-index rank-order distribution and a comparison with the impact factor rank-order distribution | Authors: | EGGHE, Leo | Issue Date: | 2009 | Publisher: | JOHN WILEY & SONS INC | Source: | JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, 60(10). p. 2142-2144 | Abstract: | We present a rationale for the Hirsch-index rank-order distribution and prove that it is a power law (hence a straight line in the log-log scale). This is confirmed by experimental data of Pyykkö and by data produced in this paper on 206 mathematics journals. This distribution is of a completely different nature than the impact factor (IF) rank-order distribution which (as was proved in a previous paper) is S-shaped. This is also confirmed by our example. Only in the log-log scale of the h-index distribution we notice a concave deviation of the straight line for higher ranks. This phenomenon is discussed. | Keywords: | power law; h-index distribution; Hirsch; impact factor distribution;power law, h-index distribution, Hirsch, impact factor distribution | Document URI: | http://hdl.handle.net/1942/9683 | ISSN: | 1532-2882 | DOI: | 10.1002/asi.21121 | ISI #: | 000270250900017 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2010 |
