Science, technology, and innovation policy researchers Luciano Kay, Alan L. Porter, Ismael Rafols, Nils Newman, and Jan L. Youtie illustrate the particular features of research and development of graphene—a new carbon-based material. The science basemap draws on data from Thomson Reuter's Journal Citation Reports of the Science Citation Index and Social Sciences Citation Index of 2009, including 61 million citation links. The patent basemap draws on data from the European Patent Office’s PATSTAT database for 2000-2006, including more than 41 million patent citation links. Both basemaps result from network visualizations of cosine-similarity matrices that reflect publication and patent citation patterns between 222 Web of Science categories and 466 International Patent Classifications (IPCs), respectively. Similar sized categories of mixed hierarchical composition were computed using the mapmaker’s own algorithm. In addition, 18 macro-disciplines—groups of subject categories—and 35 macro-patent categories—technology groups—were identified using factor analysis. The graphene overlays were generated by querying the two datasets using “graphene” and the time period 2000-2013. The resulting maps visually locate bodies of research within the sciences and technology development areas and help illustrate innovation dynamics in support of business and policy decision-making.
