Evaluation of researchers: H-Index or G-Index which is better?

Abstract

H-index measures both the quantity and quality of scientific evidence of a scientist. It is a measure of individual academic success and promotions. It also provides one of the benchmarks to assess institutional research achievements and help in institutional ranking. At present, most of the National Quality Assurance bodies in our country and globally consider the H-index while evaluating the impact of research at the individual researcher level, department level, institutional level, or university level. The calculation of the H-index does not take into consideration the higher numbers of citations in any publications. However, while comparing two scientists for academic positions or two institutes for institutional ranking, the high citations should be taken into consideration. This article tries to put forth a few points comparing H-index with the G-index and explain the use of both indices while assessing the evaluation process of researchers or institutions.
