Kevin W. Boyack and Richard Klavans share a deep interest in the mapping of science as a platform for planning and evaluation on the national, corporate, and personal levels. Through a multistep process, this galaxy-like map of science was created from citation patterns in 800,000 scientific papers published in 2002. Each dot represents one of 96,000 active research communities. Over time, communities can be born, grow, split, merge, or die. By coupling coefficients between papers, using the VxOrd layout algorithm and a modified single-link clustering routine, Boyack and Klavans were able to calculate the placement of research communities. For example, communities made up solely of papers in biochemistry journals show up in the biochemistry section, while communities that are evenly split between biochemistry and chemistry journals show up midway between biochemistry and chemistry. In 2005, this was the most comprehensive and most accurate literature map ever generated.
