This book discusses the relatively new development of interactive communication or dialog between men and computers. In this mutual exchange of information between two systems, each enjoys some independence of action, and the demand for improved information systems would be alleviated if effective communication between man and machine were…

Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

A ten-year research study designed a mechanized information system in the information processing field. Special attention was paid to implementation criteria entering into on-line retrieval through man-machine dialog from a remote typewriter or video terminal and four major areas were investigated: search strategies, machine stored indexer aids,…

The actual workings of the Educational and Career Exploration System (ECES) are described. The functions of the system are divided into three general phases: (1) an occupational information bank for exploring occupations; (2) an educational information bank for exploring training programs and educational areas of study; and (3) a junior…

The project was designed to develop a data interface system which would (1) improve the quality of vocational data, (2) provide vocational data in a more timely manner, (3) provide meaningful analyses of data (particularly in the worker demand-supply area), and (4) provide the capability of interacting different data bases. Procedures were…
