| Abstract: | A method for assessing scientific performance is proposed and illustrated. Advantages over existing methods are: (1) increased objectivity; (2) increased emphasis on what was rather than who contributed; and (3) increased accuracy in theme identification. The procedure is based on relationships displayed numerically in the published documents. These relationships are extracted and organized as a graphic display representing the conceptual structure for a subject. Individuals or groups contributing to the knowledge of the discipline can be identified. The extent of their contributions also can be documented.The method is illustrated using published documents in Pediatric Oncology for the period 1979–1982. The contributions of a major clinical investigations group, the Childrens Cancer Study Group, are analyzed. The results show increasing contributions by the Group as the conceptual structure changes from the simplest measure of survival to ones requiring sophisticated follow-up and clinical evaluation procedures. |
