Picture this: the whole of human knowledge as a figurative mind that can selectively focus on certain areas. Itâ€™s a profound notion, and visualizing such a construct is an enormous undertaking. But with last weekâ€™s release of a new â€œmap of science,â€ a team of researchers led by Johan Bollen is attempting to do just thatâ€‰â€”â€‰with a high-resolution visualization of how scientific literature is accessed based on usersâ€™ downloading and browsing behavior, known as clickstream data. This usage data was collected, aggregated, and normalized across a wide variety of journal publishers and institutions. The result is a network map with color-coded nodes (clusters of research articles from different fields) and interconnected lines (shaped by usersâ€™ clickstreams), demonstrating the connections among a comprehensive sample space of scholarly research.
I can’t find links to the actual work, which would be useful. But MESUR is available.
