MAPPING OF THE RESEARCH OUTPUT ON ‘WIRELESS COMMUNICATION (2010 - 2018)’: A WEB OF SCIENCE BASED SCIENTOMETRIC EVALUATION

The present study aimed at examining the quantitative and qualitative aspects of literature output on Wireless Communication as available and indexed in Web of Science database covering a nine year period i.e from 2010 to 2018. A total of 8482 records were downloaded from Web of Science core collection database. The downloaded records, in txt format, were exported to Bibexcel software for analyzing the data for certain quantitative and qualitative indicators. MS Excel programme was used to do all the necessary calculations and preparation of cross tables with Pivot Table options. The findings were presented under the major heads as basic metrics, author metrics, quality metrics, institution and publisher metrics, future metrics and geo metrics. The findings reveal that there is a gradual growth of publications on WLC during the study period. An exponential growth pattern was found. The Relative Growth Rate shows a decreasing trend and the Doubling time shows an increasing trend. Rather than single authored publications, multi-authored publications are more in numbers. The authors preferred to work in very small / small teams. The Degree of collaboration kept on growing throughout the study period. The researchers in WLC preferred to publish their research findings in the form of Journal articles. English is the preferred language of publications among the WLC researchers. China and USA lead the world in WLC research followed by India in the third place. Intra-county collaboration was found to be more in numbers than inter-country collaboration in WLC research output. The journals publishing research papers in WLC research do not fall in Bradford’s law of scattering. The time series analysis shows that the growth of WLC research output will be in better prospects in the years to come

Activity Index (AI) and extent of collaboration: a case study of rainwater harvesting literature with a scientometric overview

Rainwater harvesting research is being conducted in much wider perspectives from agriculture to using in house toilets. The study has assessed the research activity by different countries with the help of Activity Index (AI) and the collaboration and its impact. The SCOPUS publication records are made use of for the analysis of RWH research activities. The quality of the publications is analysed in terms of citations received to the papers and Spain has come on the top having 42 citations per paper. Cross-field relative activity in rainwater harvesting research is measured and it was interesting to note that among the leading countries conducting RWH research, a few developed countries are below world average of RWH activity. Out of the 141 countries which have at least one publication on RWH, 132 (94%) have at least one paper written in collaboration with other countries. US is the collaboration hub of many countries and the strength of collaboration of India, China, UK, Brazil is noteworthy. It was also found that there is a positive correlation between the collaboration strength and impact of papers. The results are relevant to know the relative of strength of different countries in RWH as well as boosting the collaboration among countries and researcher mobility

A global exploratory comparison of country self-citations 1996-2019

Self-citations are a key topic in evaluative bibliometrics because they can artificially inflate citation-related performance indicators. Recently, self-citations defined at the largest scale, i.e., country self-citations, have started to attract the attention of researchers and policymakers. According to a recent research, in fact, the anomalous trends in the country self-citation rates of some countries, such as Italy, have been induced by the distorting effect of citation metrics-centered science policies. In the present study, we investigate the trends of country self-citations in 50 countries over the world in the period 1996-2019 using Scopus data. Results show that for most countries country self-citations have decreased over time. 12 countries (Colombia, Egypt, Indonesia, Iran, Italy, Malaysia, Pakistan, Romania, Russian Federation, Saudi Arabia, Thailand, and Ukraine), however, exhibit different behavior, with anomalous trends of self-citations. We argue that these anomalies should be attributed to the aggressive science policies adopted by these countries in recent years, which are all characterized by direct or indirect incentives for citations. Our analysis confirms that when bibliometric indicators are integrated into systems of incentives, they are capable of affecting rapidly and visibly the citation behavior of entire countries.Comment: 42 pages, 7 figure

Fifty Years (1970-2019) Journey of \u27Journal of Documentation\u27: A Scientometric Analysis of Research Productivity and Publication Trends

Purpose In this study, we conducted quantitative analysis of 1706 scholarly literature published in Journal of Documentation during the period of 1970 to 2019 (fifty years) using a series of scientometric indicators. Annual scientific production, most local cited sources, the ranking of authors; profiles, contributions, correlation, collaboration and authorship pattern, most contributed countries, most cited articles, frequently used search terms/keywords, and the legend of historiographic mapping were analysed in detail to measure the impact of the source. Design/methodology/approach We used the Scopus database for retrieving the desired sample data. In total, 1,706 numbers of publications records were considered for the literature analysis considering their relevancy. Biblioshiny data visualization tool is used to create the various maps. Findings The present study found that annual scientific production and average citations constantly have had an uptrend. The journal\u27s had tremendous impact with an h-index of 80, with a g-index of 148, total citations of 37,161 within the studied period. Although Bawden D contributed the highest number of research papers (n=78), the work published by Hjørland B received the highest citations. Lotka\u27s Law reveals that about 75.04% of the authors (1319 authors) have one publication, and approximately 12.73% of the authors (225 authors) have two publications. The United Kingdom was the dominant country in terms of number of papers and citation count whereas University of Sheffield topped with 128 publications. The thematic map consists of eleven clusters and ‘information retrieval’ found to be the largest cluster comprehending 56 subthemes occurring 995 times. Co-citation network identified four clusters with revealing Wilson TD as the most cited authors. The study also indicates the most collaborative authors are from the United Kingdom. Research limitations/implications The study exclusively deals with 1732 published research literature indexed in the Scopus database covering a span of fifty years (from 1970 to 2019). Thus, documents which are not covered in Scopus are excluded from the purview of research. This study is significant in order to measure the impact of Journal of Documentation and useful to identify valuable research patterns from publications and of developments in the field of Information Science
