Science overlay maps: A new tool for research policy and library managementJournal of the American Society for Information Science & Technology (2010)
AbstractWe present a novel approach to visually locate bodies of research within the sciences, both at each moment of time and dynamically. This article describes how this approach fits with other efforts to locally and globally map scientific outputs. We then show how these science overlay maps help benchmark, explore collaborations, and track temporal changes, using examples of universities, corporations, funding agencies, and research topics. We address their conditions of application and discuss advantages, downsides and limitations. Overlay maps especially help investigate the increasing number of scientific developments and organisations that do not fit within traditional disciplinary categories. We make these tools available (at the Internet) to enable researchers to explore the ongoing socio-cognitive transformations of science and technology systems.
