I think publication indexes appear to measure the impact of a scientific work (mostly article) to other scientific works in general. Impact factor is using to measure a "journal"s impact, on the other hand some indexes like H-Index are using an "article"s or "author"s impact. Indexes can be created with various approaches and visions by different institutions, companies or scientific organizations. I10-Index and G-Index have created to quantify scientific productivity based on publication record mainly - like ResearcherGate's RG Score (index about the researcher's impact). You can view http://en.wikipedia.org/wiki/Impact_factor for more detailed description about impact factor, http://en.wikipedia.org/wiki/I10-index for I10-Index, http://en.wikipedia.org/wiki/G-index for G-Index and http://en.wikipedia.org/wiki/H-index for H-Index.

thank you Sattar Ebrahimi for your PDF files more useful to calculate h and I index values

i10 index is based on number of publications with 10 citations.

These may be from the members' publications of own research group.

G-index

In the Theory and practice of the g-index, Leo Egghe (2006) aims to improve on the h-index by giving more weight to highly-cited articles. The g-index is an index for quantifying scientific productivity based on publications and calculated based on the distribution of citations received by a given researcher's publications. So, given a set of articles ranked in decreasing order of the number of citations that they receive, the g-index is the (unique) largest number such that the top g articles received (together) at least g2 citations

The i10-index is the newest in the line of journal metrics and was introduced by Google Scholar in 2011. It is a simple and straightforward indexing measure found by tallying a journal’s total number of published papers with at least 10 citations (Google Scholar Blog, 2011).

The h-index is short for the Hirsch index, which was introduced by Jorge E. Hirsch (2005) as a way to quantify the productivity and impact of an individual author. Similar to how the IF is now be used to measure a journal or an author to their scientific field, the h-index has become another measure of relative impact of scientific publications. While the IF is derived from the quotient of total citations and total papers in a two-year span, the h-index is simply a count of the largest number of papers (h) from a journal or author that have at least (h) number of citations.

Wonderful question

Valuable answer from Dr.Ali .

I agree with the answer of Ali Al-Naji. Best regards.

Good question and good information

hi -index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications.

i10-Index = the number of publications with at least 10 citations.

Good contributions

I will follow Dr Ali's wonderful answer

Informative answers .... good question

Its really nice information and very good answer

It is really vip question.

its a spectacular and relevant answer for the research scholar.

Interesting question. Mr. Safari gives good explanation.

h index corresponds to a scientist's h of his/her N papers that have been cited at least h times each, while the rest of the N papers have less than h citations each. but The g-index is an index for quantifying scientific productivity based on publications and calculated based on the distribution of citations received by a given researcher's publications

All these indexes are used for rating the researcher. All the questions have already been discussed. One thing probably not raised - With passage of time, all the indexes of a researcher like h, g, i-10, e-index are bound to be increased with increased number of citations except ħ-index (hbar-index). ħ-index can be decreased over time if the researcher’s co-author vastly increases their own citations. This is the only index which takes into account the effect of multiple authorship.

Thanks and Regards

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.

I agree with Dr. Kumar......

I agree with the answer of Ali Al-Naji. Best regards.

Hi all,

Did you read this for I10-Index...?

https://www.journalsclub.com/blog/what-is-a-i10-index/

You all should read this it a great article for I10-Index. Nice article.

Thanks.

the number of publications with at least 10 citations

• The h-index reflects both the number of publications and the number of citations per publication. For example a scientist with an h-index of 20 has 20 papers cited at least 20 times.
• The i10-index is the number of articles with at least 10 citations. For instance a researcher with i10-index 3 has 3 articles cited at least 10 times.
• The g-index looks at overall record of citations from higher-cited articles to be used to bolster lower-cited articles. For instance a scientist with 20 papers, 15 of which have no citations with the remaining five having respectively 350, 35, 10, 4 and 1 citations would have a g-index of 20, but a h-index of 4 (four papers with at least 4 citations each).

i10-Index = the number of publications with at least 10 citations.

This very simple measure is only used by Google Scholar, and is another way to help gauge the productivity of a scholar.

To calculate the h-index of a scientist, find the citations of each publication, rank them according to the number of citations received, and identify the first ‘h’ publications having at least ‘h’ citations. To have a reasonably good h-index it is not sufficient to have a few publications with hundreds of citations. The use of h-index aims at identifying researchers with more papers and relevant impact over a period of time.

1. h-index is based on citation counts;

2. h-index increases over time;

3. h-index shows the linear relationship between value of h-index and time

4. h-index is time dependent;

5. g-index is greater than or equal to h-index and i-index

Thanks all for the details. I wonder if one should have a metric which measures authorship.

i10-Index is the number of publications with at least 10 citations.

What are the different between H-index and impact factor ?

h-index- number of citation divided on 10, while ih-index number of articales which every articale has citation more than 10

Thank you to all

i10 index is the number of publications cited at least 10 times.

it is the number of publications with 10 citation for each

Thanks!

Good discussion...

To manually calculate your h-index, organize articles in descending order, based on the number of times they have been cited (see below example). Suppose an author has 8 papers that have been cited 33, 30, 20, 15, 7, 6, 5 and 4 times. This tells us that the author's h-index is 6.

Articles Citations number

1 33

2 30

3 20

4 15

5 10

6 06

7 05

8 04

Thanks for all

The h-index measure both the productivity and citation impact of the publications of a scientist or scholar. On the other hand i10 index generally the number of paper with atleast 10 citations. Finally, g-index is an index for quantifying productivity in science, based on publication record.

Thanks to all for good information

Agree to M. Shahnawaz Khan . Very well explained.

h index corresponds to a scientist's h of his/her N papers that have been cited at least h times each, while the rest of the N papers have less than h citations each.

i10 index refers to the number of paper with 10 or more citations. g index is an index for quantifying productivity in science, based on publication record.

I was recently studying the topics on h-index, g-index and all. I was wondering if a scientist's contribution can truly be measured in terms of a number that is obtained based on certain criteria. I mean, there are a lot of great minds who may have done a lot of outstanding feats but only published a few papers.

Consider the name of Satyendranath Bose. He published only a few papers. One of them is the discovery of bosons.

Ramanujan self-discovered a number of works of previous great mathematicians without any formal education, which will never be named after him. A number of his own works are yet to be understood and so unpublished and uncited.

Anton von Leeuwenhoek was a spectacle maker who created a microscope to find out a number of truths on microbiology. He was never an affiliated scientist.

The point is, a lot of scientific works come to light a lot of times later. Some ideas created at one time takes the world by storm a century later. Think of the work of Gregor Mendel. He created genetics using the theory of probability and died a poor priest. So, how can a index really value such greatnesses?
