Study of different h-indices for groups of authors

摘要: In this article, for any group of authors, we define three different h-indices. First, there is the successive h-index h2 based on ranked list authors and their h-indices h1 as defined by Schubert (2007). Next, hP number publications. Finally, hC citations. We present formulae these indices in Lotkaian informetrics from which it also follows that < hp hc. give a concrete example 167 topic “optical flow estimation.” Besides h-indices, calculate two-by-two Spearman rank correlation coefficient prove rankings are significantly related. © 2008 Wiley Periodicals, Inc.
