Assessment of Research Relationship and Impact of Top Ten Authors of University of Madras: A Bibliometric Mapping

Abstract

This paper is primarily to assess and visualise the top ten prolific authors of University of Madras witnessed in Web of Science citation database in terms of quantum of publications and their respective traditional citation impacts like h-index, g-index, and non-traditional citations aka article alternative citations through Altmetric.com. The secondary aim is to focus the research collaboration, emerging topics and its clusters, preferred journals for publications and its frequency so that the fitness of Bradford’s Law is tested. Further, the correlation between publication- citations - h-index is analysed. To achieve these objectives the bibliographic data has been extracted from the Clarivate Analytics - Web of Science citation database on 18.03.2020 for all the years indexed since 1989 which extends granularity for descriptive study of prolific ten authors and their associations in the scientific publication, coherently utilising Altmetric.com for non-traditional impact upon the chosen authors. Out of 8264 total records of University of Madras, which scores 119682 citations and h-index was 107, whereas the top ten prolific authors shares 2067 records and author Velmurugan stands first with maximum number of papers (466), and authors Narayanan and Varalakshmi shares top h-index (32 each). There is a least correlation between total publications and h-index, but number of citation and h-index is highly correlated. In alternative citation category, Medical Biochemistry and Microbiology departments’ researchers attract good number of mentions through online shares and references.
