Abstract

In the field of scientific assessment of scholars, there were several metrics has been given by the scholars. From the list of indices, the h-index is widely accepted for the scientific evaluation of scholars. However, the h-index has several limitations, especially in the case of consideration of excess citation count. In this context, the e-index and EM-index have been proposed. The e-index only considers the excess citation count, while the EM-index considers both core and excess citation count. “The EM-index is the square root of the sum of the EM-index component”. In this index, every component has equal importance. But how can we consider every component equally? The first element and the 100th elements can not be identical. This article discussed the iterative weighted EM-index to address this issue. To consider the impact of all cited atricles, the multidimensional h-index and the $$EM^{\prime}$$ E M ′ -index were proposed. The multidimensional h-index has not considered the excess citation count and also not come up with any global index value. The $$EM^{\prime}$$ E M ′ -index overcomes this issue, but this index follows the same pattern as the EM-index suffers. Further to accomplish the above-discussed issue, the iterative weighted $$EM^{\prime}$$ E M ′ -index also discussed in this article. An empirical study has been performed on 82 scholars’ publications and citation data. From the empirical research, we concluded that this could be an effective solution in the scientific assessment of scholars.
