The Global Research Activity Map (GRAM) is an interactive web-based system for visualizing and analyzing worldwide scholarship activity as represented by research topics. The underlying data for GRAM is obtained from Google Scholar academic research profiles and is used to create a weighted topic graph. Nodes correspond to self-reported research topics and edges indicate co-occurring topics in the profiles. The GRAM system supports map-based interactive features, including semantic zooming, panning, and searching. Map overlays can be used to compare human resource investment, displayed as the relative number of active researchers in particular topic areas, as well scholarly output in terms of citations and normalized citation counts. Evaluation of the GRAM system, with the help of university research management stakeholders, reveals interesting patterns in research investment and output for universities across the world (USA, Europe, Asia) and for different types of universities. While some of these patterns are expected, others are surprising. Overall, GRAM can be a useful tool to visualize human resource investment and research productivity in comparison to peers at a local, regional and global scale. Such information is needed by university administrators to identify institutional strengths and weaknesses and to make strategic data-driven decisions.
