This report provides a brief general summary of progress in a 2-year project renewing earlier work on the development of Individualized Instruction for Data Access (IIDA)--a system for teaching online searching techniques for bibliographic data bases--as well as an in-depth report on the IIDA computer system design. The Connector for Networked…

A query language which is suitable for use with a relational data base system is discussed. The language is developed as an extension of ideas found in programming languages as well as relational calculus. The development is a step towards the integration of programming languages, query languages, and data base systems. The language offers a…

Defines a hash coding model for non-unique search keys and derives the expected number of accesses needed to retrieve all desired records from a computer storage device. (Author)

Discussed the Pilot State Dissemination Program, undertaken as a try-out of an educational extension and retrieval system on a sufficiently large scale to derive guidelines for future projects at the state level. (Author/RK)

Author examined the development of WORDS system and attempted to place it in an historical framework. (Author/RK)

This paper reports on a computer simulation of cloze retrieval tasks. It first outlines the ideas that were assembled and translated into the model used to compose the simulation and describes the method used in developing the simulation. It then reports on a comparison of the time required by a computer and by human subjects in responding to…

A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional…

IF COMPUTER PROGRAMS ARE TO SERVE AS USEFUL MODELS OF COGNITIVE BEHAVIOR, THEIR CREATORS MUST FACE THE NEED TO ESTABLISH AN INTERNAL ORGANIZATION FOR THEIR MODEL WHICH IMPLEMENTS THE HIGHER LEVEL COGNITIVE BEHAVIORS ASSOCIATED WITH THE HUMAN CAPACITY FOR SELF-DIRECTION, AUTOCRITICISM, AND ADAPTATION. PRESENT COMPUTER MODELS OF COGNITIVE BEHAVIOR…

Three papers are presented which delineate the foundation of theory and principles which underlie the research and instructional approach to communications at the Graduate School of Library and Information Science, University of Pittsburgh. Cybernetic principles provide the integration, and validation is based in part on a situation-producing…

The Voice Interactive Analysis System study continued research and development of the LISTEN real-time, minicomputer based connected speech recognition system, within NAVTRAEQUIPCEN'S program of developing automatic speech technology in support of training. An attempt was made to identify the most effective features detected by the TTI-500 model…

A digital computer based biomedical information system was designed to service the needs of physicians engaged in patient care and clinical research, and scientists engaged in laboratory research. The system embraces all functions of information processing which include information collection, storage, retrieval, analyses and display. The…

Project SEIC (State Educational Information Center) was funded to increase the demand for and use of educational information, especially ERIC (Educational Resources Information Center) information, and to make more cost effective delivery of information services. To accomplish these goals Project SEIC first assessed the state-of-the-art of…

Describes British Library's work on Systems Dynamics, a set of techniques for building simulation models based on analysis of information feedback loops. Highlights include macro-simulation modelling activities of social science disciplines, systems analyses and models of information retrieval processes and library services, policy models, and…

Libraries should resist the temptation to relinquish to computing centers the burden of looking after the university's digital data record resources for a growing volume of intellectually important material will arrive at the university on digital data tapes. If the user must arrange for access to this material outside the library, he will be…

Designed to help the correctional administrator meet external demands for information, this detailed analysis of the demand information problem identifies the sources of requests for and the nature of the information required from correctional institutions and discusses the kinds of analytic capabilities required to satisfy most demand information…
