Global trends in sediment-related research in earth science during 1992–2011: a bibliometric analysis

A bibliometric analysis of micro/nano-bubble related research: current trends, present application, and future prospects

“…Similarly, the China-Japan collaborations was outstanding with 36 joint publications. Collaborative countries tend to be geographically correlated and centre into the countries ranking higher in terms of total publications, which is mirrored by findings in other scientific fields (Niu et al 2014;Gao et al 2015;Mao et al 2015).…”

“…Further, although single-country articles still dominate in the micro/nano-bubble related research, international collaboration is becoming increasingly popular, which is a trend shared with other fields (Niu et al 2014). The academic collaborative relationships among the top 25 most productive countries were chosen as study samples, which were firstly grouped into different clusters in BibExcel with an algorithm developed by Persson (1994) and then graphed using Pajek (Fig.…”

“…Excluding 2566 articles without author keyword information on the ISI Web of Science, 4838 articles with author keyword information were analyzed. There were 10,724 keywords listed by authors, however, 8184 (76.3 %) keywords were used only once, 1225 (11.4 %) keywords were used twice, and the large number of once-only author keywords most likely indicated a lack of continuity in research and a wide disparity in research focus (Niu et al 2014;Li and Zhao 2015). Only 205 (1.9 %) of keywords were used more than ten times, which shows that mainstream research only consistently relates to a minority of keywords.…”

Social Media Research, Human Behavior, and Sustainable Society

“…The emerging bibliometric network analysis often analyzes the relationships among keywords, country, research institute, and author. The common network analysis includes co-word analysis [33][34][35], co-citation analysis [36,37], co-authorship analysis [38][39][40], and co-publication analysis [41]. Many disciplines have used bibliometric methods to explore the impact of research themes, such as natural science, engineering, business, social sciences, and humanities [42][43][44][45][46].…”

A bibliometric analysis of scientific trends in phytoplankton research

“…This seemed to be a common phenomenon in other research fields (Ohniwa et al, 2010;Wen and Huang, 2012;Ma et al, 2013;Niu et al, 2014). And increasing trend of publications on phytoplankton could also be found when considering the sum of six classic aquatic ecosystems (river, lake, reservoir, sea, bay and estuary), but their relative contributions remained steady, only the proportion of river showed a slight increasing trend.…”
