What is/are the difference(s) between h-index in Google scholar, SCOPUS and Web of Science (WoS)? Elaborate more on this three different h-index. In your opinion, which h- index suits you as the academician?
Google Scholar, Scopus, and Web of Science are different publishers and are the three major bibliometric databases for researchers across disciplinary. According to a physicist named Prof. Jorge Hirsch (2005), the contribution of a researcher could be measured numerically as an indication he/she has made to the field and how influential he/she is. Therefore, h-index is invented by Prof. Jorge Hirsch, where alphabet h in h-index is referred to his name, Hirsch. He explained h-index as;
“A scientist has index h if h of his/her papers have at least h citations each, and the other his/her papers have no more than h citations each.”
For instance, according to all those three databases would provide the different h-index for the same researcher/author. This happened due to the author’s numbers of publications either contained in the database(s) or not. Thus, producing the different h-index as according to the database.
In addition, according to Anne-Wil Harzing and Satu Alakangas (2015) and Alberto Martin-Martin et al. (2018), Google Scholar consistently has the largest percentage of citations across all areas of discipline. Not only the h-index measurement, also towards other key research metrics; such as the number of publications and citations.
In conclusion, I believe h-index by Google Scholar is more suitable for an academician. This is because, most publications published in Google Scholar database are freely available for any readers, thus would attract more readers for our publication. This would increase the number of citations of our publication. Not only to limit the number of readers and to spread the knowledge across the world. As well to receive the feedback from expert. However, there are also publications by Google Scholar are the subset for Scopus or Web of Science databases. Being published by two databases (Google Scholar and either with Scopus or Web of Science) would increase the value of the publication; add value for career progression and personal development.
