In this contribution we introduce the notion of a measure (or indicator) of linear type. Combining ideas related to power functions, in particular Zipf’s function, and h-type indices, we come to a novel characterization of general power functions and Zipf’s functions.

The objective of this paper is to show that the already existing h(³) indicator, designed after the h- index and Kosmulski’s h(²)-index, has some advantages with respect to the classical h- or h(²)-indices, when it comes to academic journal evaluation. The h(³)-index for journals is defined as the largest natural number h3 such that the first h3 publications each received at least (h3)3 citations. Because of its tough requirement it is difficult to have a high h(3)-index. Consequently, this inde...

We study the array of partial sums, Px, of a given array X in terms of its h-type indices. Concretely, we show that h(Px) can be described in terms of the Lorenz curve of the array X and obtain a r...

Abstract In this article we solve a minimum problem involving step functions. The solution of this problem leads to an investigation into generalized h- and g-indices. This minimum problem and the related generalized h- and g-indices are studied in a general context of decreasing differentiable functions as well as in the specific case of Lotkaian informetrics. The study illustrates the use of h-and g-indices and their generalizations in a context which bears no relation to the research evaluati...

Abstract We propose a new method for computing the bibliographic coupling strength between two documents. This new method is based on the TF-IDF formula from the field of information retrieval. It is shown that this formula is a valid alternative for the original formula introduced by Kessler and is, from a probabilistic point of view, a correction of the Vladutz-Cook formula. We further define a cosine based similarity formula generalizing the Sen-Gan coupling angle formula.

We obtain a remarkable geometric relation between the Lorenz curve of a non-negative, continuous, decreasing function Z(r) and the h-index of integrals defined over a subinterval of the domain of Z(r). This result leads to a new geometric interpretation of the h-index of Z.
