Overview of expert systems (intelligent computer applications that use data, a knowledge base, and a control mechanism to solve problems) highlights history of expert systems; construction (human element, knowledge acquisition and learning, system architecture); limitations; issues and trends; and implications for information science. Thirty-three…

Describes the mental coding processes involved in the flow of information when the user is interacting with an enabling information-retrieval (IR) system, or a system designed to stimulate the user's grasping towards a higher understanding of the information need/problem/task that brought the user to the system.

Reports on emergence of decision support system (DSS) as a practical approach for applying computers and information to problems facing management. Information processing and decision making in organizations, simulation-model-based DSS in management of library resource sharing networks, and a resource-sharing simulation system are highlighted.…

Computer-assisted instruction supplements traditional methods in a non-calculus physics course offered at Seattle Pacific College. Thirty-five science majors enrolled in the first quarter and 32 continued in the second term. The hardware for the course consists of a PDP-11/20 computer and eight teletype terminals; additional peripheral equipment…

Discusses the need for library science to examine users' search behaviors in the context of social cognition and creative problem solving. Topics covered include the psychology of search behavior, problem solving approaches to library instruction in online searching, and problem solving protocols. (29 references) (CLB)
