On the use of research categorizations as the basis for organizing knowledge: A test in the domain of information behavior in health care

This study considers the possibility of utilizing the categories employed by researchers within a subject domain as one approach for mapping the knowledge organization of that domain. The idea is tested using a sample of research reports dealing with the information behavior of people (e.g., physician, nurses, and patients) in the health care domain. It was relatively easy to identify category systems within the sample of texts. Consideration of the configuration of category systems employed across the analyzed texts shows a pattern of broad consistency. Many of the research reports employed some version of a diagnosis, treatment, and referral category system related to the information behavior of physicians, though there were many variations on this general category breakout. There were also many uses of alternative category systems (e.g., specialty area, information types, and dilemmas) that suggest the applicability and use of alternative views of the situations being studied. The key challenges for the future appear to be the specification of relations among category systems of different research reports and visualization of the identified rich relationships including the evolution of category systems over time.
