What is the difference between D index and h-index?

First, the h-index for each researcher is calculated, based on the number of publications and citations. Then a discipline-specific h-index: the D-index is calculated. The D-index is calculated by selecting publications only from the researcher's specific discipline.

What is a good D-index score?

The average D-index for the top 3% scholars is 180 against an average of 93 for all scientists included in our ranking.

What does D-index mean?

The dissimilarity index (D-Index) measures how different groups - such as women, poorer households, or ethnic minorities – fare in terms of access to a certain opportunity.

Is an h-index of 45 good?

What is an h-index? | How to calculate your h-index

Is 37 a good h-index?

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 the h-index ranking of universities?

National H-index Ranking is an international, non-commercial rating created for the unified and transparent rating of universities, scientific organizations, and scientific research institutions. The key metric is the Hirsch index, which is a well-known, popular, and stable metric in the field of scientific research.

Is Diversity Index D or 1 D?

Simpson's Index

The value of Simpson's D ranges from 0 to 1, with 0 representing infinite diversity and 1 representing no diversity, so the larger the value of D, the lower the diversity. For this reason, Simpson's index is often as its complement (1-D).

What is the h-index ranking?

The h-index is based on the highest number of papers written by the author that have had at least the same number of citations. A researcher with an h-index of 6 has published six papers that have been cited at least six times by other scholars.

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 per year is good?

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.

Does h-index really matter?

It can be useful for identifying the centrality of certain researchers as researchers with a higher h-index will, in general, have produced more work that is considered important by their peers.

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.
