Journal mapping • 16,000+ journals clustered using bib coupling of references and keywords • 554 clusters formed, cluster layout out on a sphere • Mercator projection of the spherical solution • There is one rotation of the spherical solution (i.e. from near the “South Pole”) that gives a near circle Kevin W.

Consensus among experts Klavans, R., & Boyack, K. W. (2009). Toward a consensus map of science. Journal of the American Society for Information Science and Technology 60(3), 455-476.

The circle of science Scopus data – single year (2007) Count references & apply threshold 2.1 M highly cited references Cluster references using co-citation 84,000 clusters (paradigms) Fractionally assign current papers to paradigms Order 80,000 paradigms around 5.6M current papers (2003-2007) perimeter of a circle For visualization purposes Kevin W. Boyack, 6/17/2009, NSF-JSMF Mtg.

Calculating research leadership / IDR Start with 84,000 paradigms Threshold using market share High market share paradigms Cluster paradigms using university papers Identify university strengths Calculate leadership quantities, sizes Locate distinctive competencies Identify distinctive competencies within the circle For visualization purposes Kevin W.
