Woeginger's axiomatisation of the h-index and its relation to the g-index, the h(2)-index and the R2-index
Recently Woeginger [Woeginger, G. H. (2008-a). An axiomatic characterization for the Hirsch-index.Mathematical Social Sciences. An axiomatic analysis of Egghe’s g-index. Journal of Informetrics] introduced a set of axioms for scientific impact measures. These lead to a characterization of the h-index. In this note we consider a slight generalization and check which of Woeginger’s axioms are sat...
متن کاملAn empirical investigation of the g-index for 26 physicists in comparison with the h-index, the A-index, and the R-index
J.E. Hirsch (2005) introduced the h-index to quantify an individual’s scientific research output by the largest number h of a scientist’s papers that received at least h citations. To take into account the highly skewed frequency distribution of citations, L. Egghe (2006a) proposed the g-index as an improvement of the h-index. I have worked out 26 practical cases of physicists from the Institut...
متن کاملBounds and Inequalities Relating h-Index, g-Index, e-Index and Generalized Impact Factor: An Improvement over Existing Models
In this paper, we describe some bounds and inequalities relating h-index, g-index, e-index, and generalized impact factor. We derive the bounds and inequalities relating these indexing parameters from their basic definitions and without assuming any continuous model to be followed by any of them. We verify the theorems using citation data for five Price Medalists. We observe that the lower boun...
متن کاملThe influence of transformations on the h-index and the g-index
In a previous paper we introduced a general transformation on sources and one on items in an arbitrary information production process (IPP). In this paper we investigate the influence of these transformations on the h-index and on the g-index. General formulae that describe this influence are presented. These are applied to the case that the size-frequency function is Lotkaian (i.e. is a decrea...
متن کاملAre there better indices for evaluation purposes than the h index? A comparison of nine different variants of the h index using data from biomedicine
this study, we examined empirical results on the h index and its most important variants in order to determine whether the variants developed are associated with an incremental contribution for evaluation purposes. The results of a factor analysis using bibliographic data on postdoctoral researchers in biomedicine indicate that regarding the h index and its variants, we are dealing with two typ...
