Can my 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.

Is an h-index of 55 good?

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.

Why is my h-index so low?

The number is based on the papers a researcher publishes and the citations those papers get. Publishing a lot of highly cited articles will increase your h-index. On the other hand, getting a lot of citations on only one or two papers will not give you a high h-index.

What is a good h-index by age?

It is simple to calculate. But what should be a good h-index? Hirsch2 was of the opinion that 20 h-index is Good,40 is Outstanding and 60 is Exceptional but after 20 years of research life.

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.

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

Is an h-index of 2 good?

It's calculated by dividing a scientist's h-index by the number of times that have passed since the first publication, with a score of 1 being veritably good indeed, 2 being outstanding and 3 truly exceptional.

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).

Is an h-index of 3 high?

H-index scores between 3 and 5 seem common for new assistant professors, scores between 8 and 12 fairly standard for promotion to the position of tenured associate professor, and scores between 15 and 20 about right for becoming a full professor.

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.

How do I increase my h-index?

What is the highest h-index ever recorded?

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.

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

“A typical h-index for full professors ranges from 12 to 24.” Or, as Hirsch put it: 84 per cent of Nobel prize winners in physics had an h-index of at least 30, which is outstanding (Hirsch, 2005b).

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 per year is good?

The absolute minimum some indexed scientific journals require is about 5 to 10 citations from the articles published within the last five years. But here is a more professional journal example for your understanding of scholar papers' quality.

What is a good h-index after 20 years?

Per Hirsch: h index of 20 after 20 years of scientific activity, characterizes a successful scientist.

How many citations does Albert Einstein have?

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

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.

What is a good h-index in history?

Hirsch estimated that after 20 years a "successful scientist" would have an h-index of 20, an "outstanding scientist" would have an h-index of 40, and a "truly unique" individual would have an h-index of 60.

What is the h-index in Google Scholar?

The h-index of a publication is the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3.

What is the h-index of Nobel laureates?

2; the median is at h_m = 35, lower than the mean due to the tail for high h values. It is interesting that Nobel prize winners have substantial h indices (84% had an h of at least 30), indicating that Nobel prizes do not originate in one stroke of luck but in a body of scientific work.

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.

How many citations are considered good?

Generally speaking, a good number of citations for a paper is considered to be more than 10–20 citations. However, some fields may require more or fewer citations depending on the topic and the journal.
