The $CI$-index: a new index to characterize the scientific output of researchers

Abstract

We propose a simple new index, named the $CI$-index, based on the Choquet integral to characterize the scientific output of researchers. This index is an improvement of the $A$-index and $R$-index and has a notable feature that highly cited papers have highly weights and lowly cited papers have lowly weights. In applications many researchers may have the same $h$-index, $g$-index or $R$-index. The $CI$-index can be provided an effective method of distinguish among such researchers.
