Impact of the number and rank of coauthors on h-index and π-index. The part-impact method

Abstract The publication activity of 20 Price-medallists was analysed by calculating several scientometric indices from data elite sets their publications. following (i.e. most cited papers within the total) were obtained: π -set (where number is equal to √ P , and total papers), h (in which equals Hirsch index), 2 -set, set (ECP) are more frequently than average. percentage share citations found increase in mentioned rank sets, except ECP-set. publications calculated also different part-impact methods for sharing credit among coauthors. applied take into account or coauthors by-line papers. It demostrated that any changes both -index significantly related value attributing evaluated individual. strongly depend on studied author Consequently, assessing personal contribution scientists indices, seems be highly relevant. Selecting appropriate impact method depends purpose evaluation.
