A measure of class concentration in bibliometrics

Allan D. Pratt

Journal of the American Society for Information Science, 1977, vol. 28, issue 5, 285-292

Abstract: An index of concentration for rank‐frequency distributions is proposed which permits comparison of subject and journal concentration in various fields. A mathematical model of random dispersion (the Whit‐worth distribution) of articles is suggested. Applications of the measure to several different aspects of bibliometrics are suggested. The measure holds some promise of providing a common measure by which to compare the large number of specific usage and citation studies already completed, and providing a point of departure for new ones.
