Introduction: This study investigated the effect of cognitive styles on users' information-seeking task performance using a knowledge domain information visualization system called CiteSpace. Method: Sixteen graduate students participated in a user experiment. Each completed an extended cognitive style analysis wholistic-analytic test (the…

A user-oriented computer-based information retrieval system which would not require a computer specialist as an interface between computer and user was developed. The PLATO system was chosen because it was a high-speed computer-based man-machine interaction system with convenient visual display, keyset input device, versatile programing…

A primary goal of this project was to develop an interface that would provide direct access for inexperienced users to existing online bibliographic information retrieval networks. The experiment tested the concept of a virtual-system mode of access to a network of heterogeneous interactive retrieval systems and databases. An experimental…

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…

This document is a study of the processing of questions input to computerized question-answering system such as the RAND Relational Data File. The process consists of (1)transforming the natural-language question into a symbolic question (i.e., a certain formula of predicate calculus) and (2)generating the answer by calculating the value set of…

Described is a complete and technical description of one component of the Information System for Vocational Decisions (ISVD) total data storage and access system. Both a verbal and a graphic flow chart of its functions within the system are presented. (TL)

A minimum of 30 minutes is required to learn even the rudiments of the command language (Symbolic Language). Although written instructions are helpful, practice is essential. The programmed instruction routines, which took approximately 20 minutes, were mostly of the 'yes-no' variety. Expanded routines, which would require other replies and would…

Project Intrex is a program of experiments intended to provide a foundation for the design of future information transfer systems, with the library of the future visualized as a computer-managed communications network. In order to discover the necessary facts, especially in the area of the user's interaction with the system, experimentation is…

This paper explains DASM, a package of programs and routines for Direct Access Storage Management on 70/564 disc packs. Its basic unit of data is a record. DASM processes (retrieves and maintains) records by techniques which require the user to reference a record by its name (both record and file name). The steps through which a user can create a…

After three years of preparation, the Project Intrex research team has begun to subject parts of its augmented catalog system to interactions with users who were interested in the substance of the stored information and uncontaminated by prior association with the Intrex research effort. The experiences with users to date, as well as progress made…

This report describes the current status of Project INTREX experiments and provides a detailed technical record. Activities concentrating on the bibliographic access problem involve: (1) the investigation of a digitally-encoded, machine-manipulated augmented catalog, for which the task of preparing entries for 10,000 documents is about half…

Through a description of an imitation career, the author introduces the complexities involved in programming a man-machine system which facilitates individualized career development. The interaction of man and machine is programmed, in the imitation career, because the individual descriptions of events in career chronologies, vitae and…

Discussion of the effect on the workforce of the application of electronic data processing technologies to information handling activities highlights task specialization; white collar alienation; feelings of powerlessness, meaninglessness, and normlessness in workers; the chronology of automation; and experimentation and communication. Nineteen…

Designed as a reference guide for those seeking information about systems equipment and supplies, this directory is a compilation of a selection of literature, bulletins, catalogs, manuals, and specification sheets about systems equipment and related supplies. The directory is arranged alphabetically by products. Each listing has an identifying…

This paper is the second step in the preparation of forecasts of occupational and industrial information which will meet the needs of the Information System for Vocational Decisions (ISVD). The author discusses the computation routines which need to be developed, tested and operationalized toward the goal of combining occupational and industrial…
