The main aim of this study is to analyze and compare the scientific productivity of major countries. The related data are collected from Scopus through the open-access portal www.scimagojr.com. Data has been collected on the number of documents and their rank for the top countries. Bibliometric indicators such as Compound Annual Growth Rate (CAGR) and Activity Index (AI) have been used along with a simple percentage. Further, Pearson correlation has been used to compare the rankings. Twenty-four countries have at least 1% of global scientific output in 2018, and all these top countries also ranked in Nature Index 2019 except Indonesia and Malaysia. The top two countries, the United States and China, produced more than 600,000 documents in 2018, with others following distantly. The majority of the top countries are grouped under upper-middle and high income. Fifty percent of the top countries are from Europe. Tremendous improvement in terms of global rank from 1998 to 2018 has been observed for Iran, Indonesia, and Malaysia. All the top countries focus on different disciplines. [ABSTRACT FROM AUTHOR]

This study analyzed the research productivity of Alagappa University (AU), India, in terms of scientometric and social network analysis measures. The primary aim of this study is to construct two types of networks, co-authorship, and citation, with three levels of network measures to divulge the social and intellectual structure of AU and to identify their research hubs, social interactions, the knowledge diffusion pattern, which will help to strengthen their research areas, fund allocation and to formulate appropriate policy strategies. It revealed that AU produced 99.45 % of research articles in collaboration, particularly 88.41% of the articles were the outcome of international scientific collaboration, remaining 11.04% of them have collaborated domestically. It found that the main path of the most cited publications constituted the mainstream of development of the Department of BioTechnology, AU. [ABSTRACT FROM AUTHOR]

The purpose of this study is to make a quantitative analysis and to compare scientific productivity between the countries of India and South Korea: both countries offer scholarships and fellowships for various programs and disciplines. The data are collected from SCOPUS through the open access portal www.scimagojr.com and mainly focus on rank and number of publications, global publication share and growth of publications, international collaboration pattern, quality of publications, and open access pattern. Various bibliometric indicators have been used along with simple percentage. Further, a new relative indicator Relative Open Access Index (ROAI) is proposed to compare the number of documents in an open access platform with its overall scientific production. Among the most productive countries, India is ranked at fifth and South Korea at thirteenth in the year 2018. India improved by eight positions while South Korea did by three from 1998 to 2018 at the global level. South Korea has a higher proportion of publications with international collaboration as compared to India. Both countries maintain better positions in a few disciplines such as chemical engineering and materials science. [ABSTRACT FROM AUTHOR]
