G Index Calculator

The G Index Calculator computes the G index, a metric used to measure an author's scientific productivity based on their publication citations. Unlike the H-index, which focuses on a specific threshold of citations, the G-index gives more weight to highly-cited papers.

G Index Calculation

The G-index is determined by ordering the citations from the most to the least cited. The G-index is the largest number such that the top G papers have, together, at least G² citations.

Example Calculation

If the citation counts for a researcher are: [6, 5, 3, 1, 1], the sorted list is [6, 5, 3, 1, 1].

Cumulative sums: [6, 11, 14, 15, 16]. Here, the G-index would be 3, because the top 3 papers have at least 3² = 9 citations combined.

Importance and Usage

The G-index is especially useful for capturing the performance of researchers who may have a few highly-cited papers, providing a more balanced measure of impact in comparison to the H-index.

FAQs

1. What is the difference between H-index and G-index?

   • The H-index measures the number of publications with a certain minimum citation count, while the G-index gives more weight to highly-cited papers, offering a more comprehensive view of a researcher's impact.

2. How does the G-index improve upon the H-index?

   • The G-index accounts for a researcher's most cited papers, offering a more nuanced view of their citation impact.

3. Is the G-index widely used?

   • The G-index is less commonly used than the H-index but is valued in specific contexts where highly-cited work needs to be emphasized.
