Productivity and citation impact tool is no longer an effective measure of scientific reputation, according to new analysis
Changing authorship patterns mean that the h-index is no longer an effective way to gauge a scientist’s impact, according to a new study by data scientists at technology giant Intel.
First created in 2005 by the US-based physicist Jorge Hirsch, the h-index is a measure of a researcher’s most highly cited papers. A scientist with an h-index of 30 has published 30 papers that have each been cited more than 30 times.
