Testing Lotka’s Law and Pattern of Author Productivity in the Scholarly Publications of Artificial Intelligence
Get PDFArtificial intelligence has changed our day to day life in multitude ways. AI technology is rearing itself as a driving force to be reckoned with in the largest industries in the world. AI has already engulfed our educational system, our businesses and our financial establishments. The future is definite that machines with artificial intelligence will soon be captivating over trained manual work that now is mostly cared by humans. Machines can carry out human-like tasks by new inputs as artificial intelligence makes it possible for machines to learn from experience. AI data from web of science database from 2008 to 2017 have been mapped to depict the average growth rate, relative growth rate, contribution made by authors in the view of research productivity, authorship pattern and collaboration of AI literature. The Lotka’s law on authorship productivity of AI literature has been tested to confirm the applicability of the law to the present data set. A K-S test was applied to measure the degree of agreement between the distribution of the observed set of data against the inverse general power relationship and the theoretical value of α = 2. It is found that the inverse square law of Lotka follow as such
Russian Contribution to Coronary Artery Disease Research: A Scientometric Mapping of Publications
Get PDFThe present study attempts to highlight the research output generated in Russia in coronary artery disease (CAD) research during the period 1990-2019 to understand the distribution of research output, top journals for publications, and most prolific authors, authorship pattern, and citation pattern. This study is based on secondary data extracted from the Science Citation Index (SCI), which is an integral component of the Web of Science. Descriptive and inferential statistical techniques were applied in the study. There were 5058 articles by Russian scholars in coronary artery disease during 1990-2019; they preferred to publish in Russian journals. The research contributions were in the form of research articles, meeting abstracts and reviews with a consistent drop in the number of editorial material and article; proceedings paper with time. Co-authorship was the norm in coronary artery disease research, with a steady increase in the number of multi-author documents in recent years

Do Citations make Impact on Social Media? : An Altmetric Analysis of Top Cited Articles of University of Madras, South India
Get PDFAltmetrics is an emergent research area whereby social media is applied as a source of metrics to assess scholarly impact. Over the most recent couple of years, the enthusiasm for altmetrics has developed, offering ascend to numerous inquiries in regards to their potential advantages and difficulties. As another developing field, Altmetrics has turned into a trailblazer, and got a decent arrangement of consideration by specialists associated with the assessment of logical research. This paper aims to analyse top 15 articles of University of Madras which have scored high citations. It aims to find out to what extend the top cited articles have secured altmetric scores. Do the citation score really create any impact on the social media? This is the research question formulated and comparing tool features, social media data sources, and social media events provided by Altmetric aggregators and thus they are analysed. Spearman Rank correlation metrics shows high correlation between the ranks of citations and Altmetric scores. The tweeter and Mendeley are the media through the scholarly communication highly disseminate. The analysis of readers shows that United States tops the list, followed by United Kingdom and Spain and are mainly educational ones with Ph.D, Post Graduate and Masters. The Practitioners are observed to be the voracious readers of the social media resulting in the present altmetric analysis
Testing of Lotka’s law and its Suitability to research productivity of Annamalai University, A Higher Education Institution, South India
Get PDFLotka’s Law describes the frequency of publications by authors in a given subject/discipline. In the present study, an attempt has been made to study the suitability of the Lotka’s Law to the publications of a Higher Educational institution of a region consisting of academic authors and researchers in various disciplines. Annamalai University has been ranked 20th in the state level and 56th at National level by MHRD. Annamalai University is renowned for its research output performance and has been funded for many major, minor and DST research projects. It has a large network and linkages to academia, R&D organisations and industries. It covers almost all the subjects with 10 Faculties and 49 departments of study. Examines the applicability of Lotka’s Law as a general inverse power (a # 2) and as an inverse square power relationship (a = 2) to the distribution of the research productivity Annamalai University, South India. Two datasets of the research papers (936 and 3370) contributed by Annamalai University academic authors and researchers during the period of 2000-2006 and 2011-2017 were collected from Web of Science Database.

Analysis of Scholarly Communication on Phonology during 2000 - 2017: A Scientometric Study
Get PDFThe study is aimed to find out the authorship pattern and the collaboration trends in the field of phonology. In the study, Collaborative index, Degree of collaboration, Collaborative Coefficient, Relative growth rate and Doubling time these Scientometric indicators were used. The study found that the Degree of Collaboration is 0.5 which reveals the average relationship between singled authored papers and muli-authored papers. Collaboration Coefficient and Modified Collaboration Coefficient is less than 0.5, it means there were fewer trends of authors collaboration. But the study found slight growth from 1013 to 2015 and again decreased. As per the study Goswami, U was the first ranked author, Lingua was the first ranked journal and USA was the first ranked Country between 2000 and 2017
