Abstract
Scientometric indices help rank the impact of an article, an author, and a journal in scientific literature. Additionally, it helps to rank institutions, universities, and countries in the scientific field. There are various author-, article-, and journal-level metrics provided by different service providers. It is important to know the underlying calculation method for an informed comparison between authors, articles, and journals. In this article, we described briefly some of the common author-level metrics (h-index, i10-index, and g-index), article-level metrics (Altmetric, Dimensions, and PlumX), and journal-level metrics (Impact Factor®, CiteScore, SCImago journal ranking, and h5-index).
