Citation performance indicators: Classification and importance

Abstract:

The Journal Citation Reports is an annual publication that measures the impact of scientific publications through various measures of performance; of which, the Impact Factor is the most influential. Despite the popularity of this index, its use has not been exempt from some controversy, which is why additional indicators known as Altmetrics have been proposed in recent years. In general, all these indexes are grouped according to the algorithm of calculation of metrics in: based-ratios indicators, those that are obtained by dividing the total of citations among the total of products such as the impact factor; portfolio-based indicators, which are based on scores assigned to classified documents such as the H-Index; and network-based indicators, which consider the impact of the author within a wider network of citations such as the Scimago Journal Rank. Based on exhaustive documentary research, this review presents the most important characteristics of these indexes, grouping them according to the previous classification, and discussing the advantages and disadvantages of each one of them.
