Who invented h-index?

The h index was proposed by J.E. Hirsch in 2005 and published in the Proceedings of the National Academy of Sciences of the United States of America.

Who provided the h-index?

Google Scholar usually provides the highest h-index compared to other sources. This is because Google Scholar indexes web pages not organized collections of article citations, like databases. This means Google Scholar: Counts all publications, including books.

Who is the scientist with the highest h-index?

Scientists with High H-Indexes

At the time of writing, the highest score recorded by Google Scholar is 300, by researcher Ronald C Kessler from Harvard University. JoAnn E Manson from Brigham and Women's Hospital takes second place with a score of 294.

Who calculates h-index?

The h-index can be manually determined by using citation databases or using automatic tools. Subscription-based databases such as Scopus and the Web of Science provide automated calculators. From July 2011 Google have provided an automatically calculated h-index and i10-index within their own Google Scholar profile.

What is the average h-index of Nobel winners?

What is a Good H-Index? 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.

What is an H-index? | How To Research

Is an h-index of 7 good?

On average and good H-index for a PhD student is between 1 and 5, a postdoc between 2 and 17, an assistant professor between 4 – 35 and a full professor typically about 30+.

What is a good h-index after 30 years?

h index of 60 after 20 years, or 90 after 30 years, characterizes truly unique individuals.

What is the average h-index for a full professor?

h-index scores between 3 and 5 feel common for new adjunct professors, scores between 8 and 12 fairly standard for creation to the position of tenured associate professor, and scores between 15 and 20 about right for coming a full professor.

What was Isaac Newton's h-index?

Isaac Newton's h-index is 59.

What is better than h-index?

How many people have h-index above 100?

The database shows 5,882 scholars across the world have an h-index at or above 100. The h-index is a gauge of productivity and the impact of published papers. The index takes into account the researcher's total number of papers and how many times each was cited by other scholars.

When was h-index invented?

Love it or hate it, the h-index has become one of the most widely used metrics in academia for measuring the productivity and impact of researchers. But when Jorge Hirsch proposed it as an objective measure of scientific achievement in 2005, he didn't think it would be used outside theoretical physics.

When was the h-index created?

Jorge Eduardo Hirsch was Professor of Physics at the University of California who introduced the h-index (Hirsch Index) in 2005 for the first time.

Do people care about h-index?

People want a higher h-index because it implies higher impact which awards more respect and accolades. h-index was suggested in 2005 by Jorge E. Hirsch as a way to measure other physicists' research quality.

Is 1,000 citations a lot?

Most authors of highly cited papers have fewer than 1000 citations, which is very little in comparison with the highest numbers indicated in the top part of Table S1. Table S1 shows a high degree of rank–rank correlation between the number of citations, h-index, and scientific degree, which are over 0.9 (citations vs.

How many citations does Albert Einstein have?

For his 147 articles, Einstein has received 1,564 citations during his lifetime.

What are the disadvantages of the h-index?

The limitations of the h-index include: 1. It does not take into account the total number of citations. For example, imagine that another scholar also has 15 publications, and also 8 of them have more than 8 citations, but each of the first five were cited more than a thousand times.

Which is the most cited paper ever?

Most-cited papers

The most-cited paper in history is a paper by Oliver Lowry describing an assay to measure the concentration of proteins. By 2014 it had accumulated more than 305,000 citations. The 10 most cited papers all had more than 40,000 citations.

Can h-index go down?

The h-index is influence both by quantity (Scholarly Output) and publication impact (Citation Count). Originally conceived as a useful reflection of a researcher's accumulated career, it is represented by a single number which stays the same or increases with time – it cannot go down.

What is a good h-index for a doctor?

Another finding from exploratory analyses is that an h-index at least equal to the number of years since first publications (m-index = 1) may be a good rule of thumb to indicate excellent citation achievement in medicine (19).

What is a good h-index after 5 years of research?

One rule that is widely accepted, however, is that an h-index score should at least be equal to the number of years a scholar has put into his or her work. This rule was prescribed by Hirsch who recommended an h-index of at least 20 after working for the same number of years.

How many citations is good for a professor?

The difference between professors and associate professors begin rather to manifest at higher levels of performance, above around 15 publications and 100 citations. In numbers of individuals, 316 have more than 15 publications and 300 have more than 100 citations.

How do I increase my h-index?
