H-index is the most widely used metrics to quantify a researcher’s research output regarding productivity and impact. A researcher with a H-index value 20 implies that this researcher has published 20 publications that have received at least 20 citation counts.
You may set up your author profile in Web of Science, Scopus, or Google Scholar for updating the H-index. The databases will calculate the H-index based on the publications included in your author profile.
