Abstract
Albarran et al. (2011a) introduced a novel methodology for the evaluation of citation
distributions consisting of a pair of high- and a low-impact measures defined over the set of
articles with citations below or above a critical citation level CCL. Albarran et al. (2011b)
presented the first empirical applications to a situation in which the world citation distribution
in 22 scientific fields is partitioned into three geographical areas: the U.S., the European Union,
and the rest of the world. In this paper, we compare our results with those obtained with
average-based indicators. For reasonable CCLs, such as the 80th percentile of the world citation
distribution in each field, the cardinal differences between the results obtained with our high-impact index and the mean citation rate are of a large order of magnitude. When, in addition,
the percentage in the top 5% of most cited articles or the percentage of uncited articles are used, there are still important quantitative differences with respect to the high- and low-impact indicators advocated in our approach when the CCL is fixed at the 80th or the 95th percentile.
