EM-index: a new measure to evaluate the scientific impact of scientists

Assessing the Scientific Impact of Individual Scholars With Multi-Scale H-Index

“…To comprehensively evaluate our proposed multi-scale hindex scheme, following [27], we collect the citation data of 82 scholars in the scientometrics and bibliometrics fields from Google Scholar. Those scholars are in the same research community, such that there is no domain gap in their publication and citation records for assessment and comparison.…”

“…The e-index suffers an issue that once the citation counts of those top h articles are all equal to h, the obtained e-index is equal to 0, which is unreasonable. Another recent variant is EM-index [27], which adopts the concept of multi-dimensional h-index. Concretely speaking, for a scholar with article citations…”

“…Towards this goal, [34] proposed a novel two-sided h-index. Bihari et al [27] further extended their EM-index to EM'index by considering the citation counts of all articles after subtracting the h-index from the h-core articles.…”

“…Although simple and useful, the h-index suffers a nontrivial limitation that no additional credit is given to those highly cited articles, whereas every citation counts on scientific evaluation [8] [9] [10] [11] [12] [13] [14] [15]. To address this weakness, many h-index variants are proposed, such as g-index [16] [17], AR-index [18], R-index [18], Tapered hindex [19], Hg-index [20], q-2 index [21], PR-index [22], ch-index [23], t-index [24], π-index [25], w-index [26], EMindex [27], etc. To give credit to excess citation count, some other index schemes are proposed, such as e-index [28], jindex [29], Hl-index [30], and EM-index [27].…”
