Co-Cited Author Mapping as a Valid Representation of Intellectual Structure
Journal of the American Society for Information Science and Technology, Vol.37(3)

Abstract
It has been assumed that the intellectual structure of a scientific field can be portrayed by mapping the pattern of author co-citations from the field's literature core. An attempt was made to validate this assumption by comparing co-citation mappings for 90 authors in the fields of macroeconomics and fruit fly genetics to judgments of author similarity. These assessments were obtained from independent samples of 14 macroeconomists and 15 geneticists. All authors identified in co-citation analysis were listed individually on cards, and independent judges sorted cards according to the perceived similarity of authors. Two-dimensional mappings of author clusters were generated using nonmetric multidimensional scaling and ''smallest-diameter'' clustering. Canonical correlation analysis revealed significant agreement between clusters of co-cited authors and those independently judged to be similar. Observed variation between author clusters in macroeconomics primarily were due to perceptions of authors' policy orientations, while in genetics, they arose from time lags in the publication of authors' most recent research.
