Hirsch reckons that after 20 years of research, an h-index of 20 is good, 40 is outstanding, and 60 is truly exceptional. In his paper, Hirsch shows that successful scientists do, indeed, have high h-indices: 84% of Nobel prize winners in physics, for example, had an h-index of at least 30. Limitations of the h-Index The H or H-Index is a numerical scale that shows how effective a researcher has been. The index was invented in 2005 by a physicist named George Hirsch at the University of California. The purpose of inventing this numerical scale was to determine how successful each researcher was in their scientific field.

Physicist Hirsch (2005) introduced an indicator for quantifying the research output of scientists that has ever since been discussed and studied theoretically and empirically in a number of disciplines (Bornmann and Daniel, 2007, Bornmann and Daniel, 2009). Let's go on a journey and learn about indexes and scales as a way of measurement in research! But even if you do not have access via your institution, you can use the free author look-up to query your h-index. Even though Scopus needs to crunch millions of citations to find the h-index, the look-up is pretty fast because Scopus has already prepared individual pages for most researchers, where you will find details about the publication records including the h-index .

H index scale

The limitations of the H‐index are that one could have a high H‐index and not be a first/last author on any of them or not have published in 10 years. Conversely, one could have a low H‐index, Scale of the Universe 2 2019-08-04 2021-03-14 To add to thee confusion, scale and index. techniques can be combined in one measure.

2003;8(3):288-93. doi: 10.1007/s10776-002-0629-0. The h-index is an author-level metric that measures both the productivity and citation impact of the publications of a scientist or scholar. The h-index correlates with obvious success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities.

An H below 0.15 (or 1,500) indicates an unconcentrated industry.

The HHI is calculated by adding up the squared market shares of firms in a given market. For example, for a market with 5 firms, with market shares of 30%, 25%, 20%, 15% and 10%, the HHI would be: Number h of works that each have at least h citations.Authors with multiple affiliations are attributed to each according to the weights they have set to each in their profile, or by default according to a formula described here.
