The single publication H-index and the indirect H-index of a researcher

Viva the h-index

In their article ‘The inconsistency of the h-index’ Ludo Waltman and Nees Jan van Neck give three examples to demonstrate the inconsistency of the h-index. As will be shown below, a little extension of their examples just illustrate the opposite, a stable feature of the h-index. For starting authors it, the h-index that is, focusses on the number of articles; for experienced authors its focus s...

Socializing the h-index

A variety of bibliometric measures have been proposed to quantify the impact of researchers and their work. The h-index is a notable and widely-used example which aims to improve over simple metrics such as raw counts of papers or citations. However, a limitation of this measure is that it considers authors in isolation and does not account for contributions through a collaborative team. To add...

An updated h-index measures both the primary and total scientific output of a researcher.

The growing interest in scientometry stems from ethical concerns related to the proper evaluation of scientific contributions of an author working in a hard science. In the absence of a consensus, institutions may use arbitrary methods for evaluating scientists for employment and promotion. There are several indices in use that attempt to establish the most appropriate and suggestive position o...

Restricting the h-index to a publication and citation time window: A case study of a timed Hirsch index

The h-index has been shown to increase in many cases mostly because of citations to rather old publications. This inertia can be circumvented by restricting the evaluation to a citation time window. Here I report results of an empirical study analyzing the evolution of the thus defined timed h-index in dependence on the length of the citation time window. 1. Introduction A recently popular meas...
