This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

The computer language FOL is intended to facilitate the implementation of file organizations for information storage and retrieval systems. In many information storage and retrieval applications the designer, initially, does not know how best to organize a data base for efficient retrieval and ease of updating and modifying. It is felt that FOL…

INFOL for the CDC 6400 is a rewrite in FORTRAN IV of the CDC 3600/3800 INFOL (Information Oriented Language), a generalized information storage and retrieval system developed by the Control Data Corporation for the CDC 3600/3800 computer. With INFOL, selected pieces of information are extracted from a file and presented to the user quickly and…

This annual report of the Department of Computer and Information Science at Ohio State University for July 1977-June 1978 covers the department's organizational structure, objectives, highlights of department activities (such as grants and faculty appointments), instructional programs/course offerings, and facilities. In the second half of the…

The trend toward on-line utilization of computers in recent years has included the emergence of computer support systems to fill the information processing needs of individuals engaged in scientific research. In this study, a new approach to document description is applied to the design of a personal information storage and retrieval system,…

Intended for teaching applications programing for libraries and information centers, this volume is a graded workbook or text supplement containing typical practice problems, suggested solutions, and brief analyses which emphasize programing efficiency. The computer language used is Programing Language/One (PL/1) because it adapts readily to…

STGPROC is a computer program designed to meet a need in the social sciences for a computing system that (1) can handle character strings of open-ended data, (2) does not require predefinition of the data, and (3) can handle variable numbers of responses per respondent. The purpose of this monograph is to allow the researcher to judge the utility…

A series of three booklets provides elementary and secondary students who are participating in the Southeast Alternatives Program run by Special School District Number 1 in Minneapolis with some fundamental information about computers and their use. The first volume offers some general background on computers and describes the use of the teletype…

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 Canadian Department of Education developed this manual to provide teachers and administrators with information about the potential use of computers. Part I describes at length the five components of the computer input, output, storage, control, and arithmetic/logic functions) and gives a discussion of computer languages, programing, batch…

The image generator function and author language software support for the CHARGE (Color Halftone Area Graphics Environment) Interactive Graphics System are described. Designed initially for use in computer-assisted instruction (CAI) systems, the CHARGE Interactive Graphics System can provide graphic displays for various applications including…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…
