Can anyone please explain me what is "H-index" and how can find my H-index?
I think it should be index-h
Imagine a graph in which the Y-axis represents the number of citations each of your papers has received and the X-axis is the number of papers you have published. Then graph each of your papers starting with the highest cited paper at X = 1 and going down the line sequentially to your least or uncited papers. If you then draw a line y=x, the H-index will be at the intercept of this line with your data. Obviously, the plotted data can be selected based on time period (last 5 years) etc.
H is meant to represent a measure of both quality and quantity. It can be very different to mean citation data (impact factor) as such data can be heavily influenced by a few highly cited papers.
If you've only published one paper and it was cited once, then H=1. If that paper was cited 50 times, then H still = 1.
If you've published 20 papers and all 20 have been cited 20 times, then H = 20. But if the highest citation at which x= y is 10, then H = 10. In other words, 10 papers got ≥ 10 citations and the rest < 10 citations.
If you think about it, each rise in H becomes more and more difficult, because you not only have to publish another paper that climbs to the next citation level, but all the papers at the current H level have to have at least one additional citation as well. In the last example to go from H = 10 to H = 11, you would have to have 11 papers with ≥ 11 citations.
I've only found calculated H-factors on subscription services such as web-of-science and SCOPUS. Their numbers will differ because they don't track the exact same publications. You can use GoogleScholar to look up your papers and see how often they got cited to calculate H for yourself.
Thank you TheFFM and Carson.
Carson you have given as much details as to understand. Many thanks!
I got an add-on offered by Firefox "Scholar H-Index Calculator", I believe that would give exact index. I will try to match it with google scholar index and find the best one.
Looks interesting, I'll give it a try.
Thanks for sharing!
I am sharing the link to find citation index on year wise and also 'h' index:
