What is the h-index weakness?

Limitations of the h-index include the following: It does not take into account the number of authors on a paper. A scientist who is the sole author of a paper with 100 citations should get more credit than one on a similarly cited paper with 10 co-authors. It penalizes early-career scientists.

Why is h-index flawed?

Disadvantages of h-index

If a researcher has a limited number of papers but they are highly cited, the H-index will not be high. H-index does not review the citation text. Many articles may be cited in one article, only using one sentence of them, but the focus of the research be only on a few specific articles.

Why might the h-index be an issue for researchers?

The h index is insensitive to publications that are rarely cited such as meeting abstracts and to publications that are frequently cited such as reviews. Author name variant issues and multiple versions of the same work pose challenges in establishing accurate citation data for a specific author.

What are the strengths of the h-index?

Strengths of the h index

The h index corrects for the disproportionate weight of highly cited publications or publications that have not yet been cited. Several resources automatically calculate the h index as part of citation reports for authors.

What are the advantages of the h-index?

The h-index offers a consistent estimation method about a researcher's overall scientific achievements since it combines the total number of publications (i.e., productivity) and the number of citations (i.e., quality of those publications).

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

Is the h-index good or bad?

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.

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 is better than h-index?

The g-index gives more weight to highly-cited articles (whereas the h-index is insensitive to it) Someone's g-index will always be equal to or greater than the h-index.

Why does h-index matter?

With careful analysis and the right amount of reflection, the H-index can give you clues and ideas on how to design and implement future projects. If your paper is not being cited as much as you expected, try to find out what the problem might have been.

What should be a good h-index at least?

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.

Who has the highest h-index in the world?

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.

How do you explain h-index?

The h-index is calculated by counting the number of publications for which an author has been cited by other authors at least that same number of times. For instance, an h-index of 17 means that the scientist has published at least 17 papers that have each been cited at least 17 times.

How do I improve my h-index?

Is 70 a good h-index?

The statistical variance in the data set was quite large so the averages should be taken with a grain of salt. The same study found that if you are aiming for a Nobel Prize, your h-index needs to be at least 35 and preferably much closer to 70.

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 impact factor or h-index more important?

Your colleagues are right though. As a researcher, it is more useful for you to calculate your h index than to use the journal impact factor as a measure of prestige. The h index can especially work to your advantage if you have published many papers.

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 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.

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 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 h-index vs impact factor?

Journal impact factor (which reflects a particular journal's quality) and H index (which reflects the number and quality of an author's publications) are two measures of research quality. It has been argued that the H index outperforms the impact factor for evaluation purposes.

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

h-index is based on the set of the researchers most cited papers and the number of citations that they have received in other publications. i-10-index is the number of publications with at least 10 citations.
