The Kardashian Index (K-Index), named after media personality Kim Kardashian, is a satirical measure of the discrepancy between a scientist's social media profile and publication record.

The h-index is an author-level metric that measures both the productivity and citation impact of the publications, initially used for an individual scientist or scholar. The h-index correlates with success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. [1]
Author-level metrics are citation metrics that measure the bibliometric impact of individual authors, researchers, academics, and scholars. Many metrics have been developed that take into account varying numbers of factors (from only considering the total number of citations, to looking at their distribution across papers or journals using statistical or graph-theoretic principles).
The most common article-level citation metric is the number of citations. [1] Field-weighted Citation Impact (FWCI) by Scopus divides the total citations by the average number of citations for an article in the scientific field. [2] Alternative article-level metrics include the CD index, a measure of the disruptiveness of an article. [3] [4]
h-index – usually used as a measure of scientific productivity and the scientific impact of an individual scientist, but can also be used to rank journals. h5-index – this metric, calculated and released by Google Scholar, is based on the h-index of all articles published in a given journal in the last five years. [3]
The papers introducing the ranking have been quoted extensively by authors working in Bibliometrics and Scientometrics.For example, reference [3] describing an update to the methodology of this index number is cited [12] from authors publishing in journals such as SAGE's Research on Social Work Practice, [10] Elsevier's Perspectives in Ecology and Conservation, [13] Springer's Forensic Science ...
