VARIOUS METRICS: A FOCUS ON GOOGLE SCHOLAR - A CASE STUDY

Abstract

This study compares Google Scholar with other research evaluation tools like Web of Science and Scopus, analyzing their strengths and weaknesses. It delves into various metrics used in academic research evaluation, such as citation counts, h-index, and journal-level metrics like Impact Factor. The study also explores modern metrics like altmetrics, i10 index, G-index, and h-core. Launched in 2004, Google Scholar offers comprehensive research coverage, including web citations and references, outperforming Web of Science and Scopus. Google Scholar Metrics and Scopus provide h-index and citation counts for research evaluation, along with metrics like Eigenfactor, CiteScore, and Altmetrics for impact assessment. Google Scholar Metrics assist authors in gauging the impact of their recent articles in scholarly publications. The top 100 publications are ranked based on their five-year h5-index and h5-median metrics, covering articles published between 2019 and 2023 with citations in Google Scholar up to July 2024. The top 10 publications are determined by their combined h5-index and h5-median scores, with the New England Journal of Medicine ranking first at 13.26% and Nature at 12.29%. The study also lists the top 10 funding agencies supporting the indexing of journals in the country on Google Scholar, with the European Commission leading at 87% and the Government of Spain at 80%. Google Scholar indexes 8 major subjects globally, with the highest number of publications in health and medical sciences (69 subcategories) and engineering and computer science (56). It includes non-English publications from Africa, Asia, and Central and South America, making it a valuable tool for searching scholarly literature across disciplines. Users can access scholarly literature, including articles, theses, and books, from academic publishers, professional societies, and online repositories. Key features include searching for literature, exploring related works, citations, authors, and publications, accessing complete documents, staying updated on research, and tracking citations through a public author profile. This study tested the hypothesis.
