Davis P. Citation performance indicators - A very short introduction. The Scholarly Kitchen 2017 May 15
This post provides a brief summary of the main citation indicators used today. It is not intended to be comprehensive, nor to opine on which indicator is best. The goal is simply to highlight their salient strengths and weaknesses. These citation indicators are grouped based on the design of their algorithm: the group Ratio-based indicators is built on the same model as the Impact Factor, by dividing citations counts by document counts; the group Portfolio-based indicators calculates a score based on a ranked set of documents; and the last group Network-based indicators seeks to measure influence within a larger citation network.
