Abstract

During the last decade, several scientometrics as well as bibliometrics indices were proposed to quantify the scientific impact of individual. The h-index gives a breakthrough in scientific evaluation, but this index suffers with big hit problem, i.e., once a paper is selected in h-core publication, further citation of h-core articles is not considered in scientific evaluation. To overcome this limitation of h-index, the e-index was proposed, but it does not consider the core citation count. It considers only the excess citation count. To overcome this limitation, the EM-index is proposed in this article. The EM-index is the extension of h-index and e-index, which uses the concept of multidimensional h-index. The EM-index uses all citation counts of h-core articles at multi-level to quantify the scientific impact of the individual. But this index does not consider all publication citations. To overcome this limitation of EM-index a multidimensional extension of the EM-index is also proposed called EM′-index. To validate the proposed indicators, an experimental analysis has been done on 82 scientist’s publication citation count, who are working in scientiometrics field. In such a way, we found a more balanced and fine-grained approach to evaluate the scientific impact of individual as well as to compare the scientific impact of two different researchers/scientists.
