Enter the total number of publications, the total number of citations for the most cited paper, and the total number of years since the first publication into the calculator to determine the G Index.
G Index Formula
The following formula is used to calculate the G Index.
G = sqrt(P * (D / T))
Variables:
- G is the G Index
- P is the total number of publications
- D is the total number of citations for the most cited paper
- T is the total number of years since the first publication
To calculate the G Index, multiply the total number of publications by the total number of citations for the most cited paper. Then divide this result by the total number of years since the first publication. Finally, take the square root of the result to get the G Index.
What is a G Index?
A G Index is a metric used in academic publishing to measure the productivity and impact of a scientist’s work. It was proposed by Leo Egghe in 2006 as an improvement over the H-index. The G Index takes into account the citation count of an author’s most cited papers, giving more weight to highly-cited articles. It is calculated by ranking an author’s articles by the number of citations they received, and finding the largest number where the top G articles have together received G^2 or more citations.
How to Calculate G Index?
The following steps outline how to calculate the G Index.
- First, determine the total number of publications (P).
- Next, determine the total number of citations for the most cited paper (D).
- Next, determine the total number of years since the first publication (T).
- Next, gather the formula from above = G = sqrt(P * (D / T)).
- Finally, calculate the G Index.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total number of publications (P) = 50
total number of citations for the most cited paper (D) = 100
total number of years since the first publication (T) = 10
