How do readers of science journals use online sources? A new paper offers a new map, based on analyses of users’ clicking patterns. “Clickstream Data Yields High-Resolution Maps of Science” (Bollen, Van de Sompel, et al) studies how readers worked through a series of portals, including JSTOR, Scopus, and Web of Science. The results show interesting patterns of interdisciplinarity:
…alternative energy (rim, 3PM) connects to pharmaceutical research and chemical engineering, which itself further connects to toxicology studies and biotechnology. Brain research (rim, 6PM) is connected to genetics, biology, animal behavior, and social and personality psychology. Human geography studies connects to geography, plant genetics, and finally agriculture. A number of clusters are well-connected to both the natural science and social science clusters. For example, ecology and biodiversity (5PM) connects the domains of biology (rim, 5PM) and architecture and design (hub, 5PM). Production and manufacturing (12PM) bridge the domains of physics and engineering (rim, 2PM) and economics (hub, 11PM).
