A citation-based, author- and age-normalized, logarithmic index for evaluation of individual researchers independently of publication counts

Abstract: The use of citation metrics for evaluation of individual researchers has dramatically increased over the last decade. However, currently existing indices either are based on misleading premises or are cumbersome to implement. This leads to poor assessment of researchers and creates dangerous trends in science, such as overproduction of low quality articles. Here we propose an index (namely, the L-index) that does not depend on the number of publications, accounts for different co-author contributions and age o… Show more

“…Other measures such as impact, readership and translation were not recorded in the present study and may be important factors in the contemporary political climate. Even within the field of bibliometrics, some authors suggest alternative measures such as the L‐index that help to control some of the limitations of the H‐index. In the present study, these metrics would have been cumbersome to calculate as the Scopus database does not yet automatically calculate this metric.…”

“…The Kendalls coefficient of concordance (W) [35] was computed to examine the internal consistency(IC) of the data(i.e., the four indices of h, g, x, and L indexes as well as author impact factor (AIF)) [36][37][38][39][40][41] related to MeSH clusters. If the agreement is accepted by the statistical al-pha level (<0.05), [42] the following analysis of one-way ANOVA for inspecting the difference in mean of indices is meaningful.…”

“…Az L-index egy olyan logaritmikus index számítási módszer, amely nemcsak a hivatkozások darabszámát veszi figyelembe, hanem a társszerzőket és a cikk írásának időpontját is [11]. A 2.1 képletben N a szerző cikkeinek a darabszáma, Hi a szerző i-edik cikkére történt hivatkozások száma, Si az i-edik cikk szerzőinek a száma, és Ki a szerző életkora az i-edik cikk írásának évében.…”
