    A theoretical model of the relationship between the h-index and other simple citation indicators

  • Popis výsledku v původním jazyce

    Of the existing theoretical formulas for the h-index, those recently suggested by Burrell (J Informetr 7:774-783, 2013b) and by Bertoli-Barsotti and Lando (J Informetr 9(4):762-776, 2015) have proved very effective in estimating the actual value of the h-index Hirsch (Proc Natl Acad Sci USA 102:16569-16572, 2005), at least at the level of the individual scientist. These approaches lead (or may lead) to two slightly different formulas, being based, respectively, on a &quot;standard&quot; and a &quot;shifted&quot; version of the geometric distribution. In this paper, we review the genesis of these two formulas-which we shall call the &quot;basic&quot; and &quot;improved&quot; Lambert-W formula for the h-index-and compare their effectiveness with that of a number of instances taken from the well-known Glänzel-Schubert class of models for the h-index (based, instead, on a Paretian model) by means of an empirical study. All the formulas considered in the comparison are &quot;ready-to-use&quot;, i.e., functions of simple citation indicators such as: the total number of publications; the total number of citations; the total number of cited paper; the number of citations of the most cited paper. The empirical study is based on citation data obtained from two different sets of journals belonging to two different scientific fields: more specifically, 231 journals from the area of &quot;Statistics and Mathematical Methods&quot; and 100 journals from the area of &quot;Economics, Econometrics and Finance&quot;, totaling almost 100,000 and 20,000 publications, respectively. The citation data refer to different publication/citation time windows, different types of &quot;citable&quot; documents, and alternative approaches to the analysis of the citation process (&quot;prospective&quot; and &quot;retrospective&quot;). We conclude that, especially in its improved version, the Lambert-W formula for the h-index provides a quite robust and effective ready-to-use rule that should be preferred to other known formulas if one&apos;s goal is (simply) to derive a reliable estimate of the h-index.
