Simulation of a Schema Theory-Based Knowledge Delivery System for Scientists.
Vaughan, W. S., Jr.; Mavor, Anne S.
A future, automated, interactive, knowledge delivery system for use by researchers was tested using a manual cognitive model. Conceptualized from schema/frame/script theories in cognitive psychology and artificial intelligence, this hypothetical system was simulated by two psychologists who interacted with four researchers in microbiology to define functional measurements for computer applications. The system worked in real time to provide knowledge delivery services to real research problems through three phases of systems operations--diagnosis, search, and product design. Main systems elements included research paradigms as procedural scripts, information needs as weakly specified frame terminals, and content models as frames. The system's schema enables it to generate representations of information needs as schemata, to plan and conduct targeted searches for relevant information, and to use its inductive and deductive inferencing capabilities. Appendices include interviewing procedures to generate topics and methodological paradigms as well as case studies of actual searches. Nineteen references are included. (Author/RAA)
