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

The circle of science

Scopus data – single year (2007) 2.1 M highly cited references

Count references & apply threshold

84,000 clusters (paradigms)

Cluster references using co-citation

5.6M current papers (2003-2007)

Fractionally assign current papers to paradigms For visualization purposes

Order 80,000 paradigms around perimeter of a circle

SLIDE 6

Calculating research leadership / IDR

Identify university strengths

Cluster paradigms using university papers

Identify distinctive competencies

Calculate leadership quantities, sizes

Start with 84,000 paradigms High market share paradigms

Threshold using market share For visualization purposes

Locate distinctive competencies within the circle
