A modular program is recommended for automation of the clippings file of "The Daily Texan" (student newspaper of the University of Texas at Austin). The proposed system will lead ultimately to on-line storage of the index, on-line storage of local, staff-written news stories from the previous twenty-four months, micrographic storage for backup and…

The information retrieval demonstration and research project was designed to demonstrate the computer terminal system of information retrieval from a central computer. Specifically, the system concentrated on computer searching of the ERIC system. The demonstrations took place by locating nine terminals in volunteer districts and conducting…

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…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

Interactive computers are providing more services to greater numbers of users. However, before such systems can be economically applied to public education, the cost of high performance memory must be reduced. By using massive amounts of serial memory in conjunction with a highly sophisticated memory controller, a system was constructed which…

The Air Force Logistics Command (AFLC) is revising and enhancing its data-processing capabilities with the development of a large-scale, multi-site, on-line, integrated data base information system known as the Advanced Logistics System (ALS). A data integrity program is to be built around a Data Base Manager (DBM), an individual or a group of…

The computational complexity of a formal process for the construction of term classes for information retrieval is examined. While the process is proven to be difficult computationally, heuristic methods are applied. Experimental results are obtained to illustrate the maximum possible improvement in system performance of retrieval using the formal…

The report describes Wisconsin's information retrieval system with remote, on-line computer access to nearly 200,000 educational documents. Briefly outlined are the operations and indexing of materials for the computer program, documents of the Educational Resources Information Center (ERIC), file access, training sessions, and remote location…

The Ministry of Agriculture, Fisheries and Food conducted an operational evaluation of the software packages CAIRS and STATUS, which were used to build databases and databanks. Setting up the trial, types of data involved (chemical products used as pesticides), searching and presentation of data, and the final choice are covered. (EJS)

Abstracts of research papers in computer and information science are given for 68 papers in the areas of information storage and retrieval; human information processing; information analysis; linguistic analysis; artificial intelligence; information processes in physical, biological, and social systems; mathematical techniques; systems…

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

A feasibility study was made to define, within the conceptual framework and in accordance with the recommendations of the UNISIST program, the managerial, technical, legal, and financial framework for the setting up of an International Science and Technology Policies Information Exchange System (SPINES). This report describes in some detail the…

The twenty-second in a series, this report describes research in information organization and retrieval conducted by the Department of Computer Science at Cornell University. The report covers work carried out during the period summer 1972 through summer 1974 and is divided into four parts: indexing theory, automatic content analysis, feedback…

This project report describes the process used to convert the retrospective life history data collected in 1969 at the Center for Social Organization of Schools at the Johns Hopkins University to a more usable form, the writing and testing of computer storage and retrieval programs for the data, and the initial interpretation of data relating to…
