colored according to the geographic location of that researcher, as indicated in the figure.7 Three large circles marked by dotted lines are used to bin the hubs of research activity by each of their associated areas of research (e.g., semiconductor scaling, architecture, and parallel programming).
It is worth noting that this mapping approach differs from traditional bibliometric analyses of coauthored publication data because the primary nodes (hubs) examined were identified based on the committee’s data input solicitations (as opposed to selecting hubs on the basis of total number of publications or of most cited
7Color coding by region (e.g., U.S., Asia, Europe, Other) was determined by using each authors’ geographic location listed on his or her conference publication. Addresses were not mapped using Sci2 software.
