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 National Library of Medicine maintains a computerized analysis and retrieval system and administers various programs for collecting, publishing, disseminating, and exchanging medical health information. A major use of the library's computer is to prepare bibliographies of biomedical subjects requested by medical schools, researchers,…

Discusses tax preparation and planning programs for microcomputers, including how programs save time and money, how they may or may not perform calculations accurately, how they compare to services offered by professional tax preparers, and the deduction of software costs. Ten tax programs are listed and described. (MBR)

Considered the problems of excessive accumulation of records, designed to assist schools in evaluating students, which ultimately invade the privacy of individuals. (RK)

An archive of still images in videodisc format becomes a powerful instructional tool when complemented by a computer data base system for selection and retrieval and programs to generate materials and manage image presentation. Considerations in using this potential include database design, a classification system, and computer-videodisc…

Outlines the important factors to be considered in selecting a database management system for use with a microcomputer and presents a series of guidelines for developing a database. General procedures, report generation, data manipulation, information storage, word processing, data entry, database indexes, and relational databases are among the…

This manual describes a text processing system developed to teach relatively inexperienced users how to enter and edit textual materials. Also provided is information on storage and system maintenance for the system manager. It contains nine sections and two appendices with sections two through nine arranged in a sequence which corresponds closely…

The purposes of this study were to determine the nature of human semantic memory and to obtain knowledge usable in the future development of computer systems that can converse with people. The work was based on a computer model which is designed to comprehend English text, relating the text to information stored in a semantic data base that is…

A generalized file-conversion program suite for the EUDISED (European Documentation and Information System for Education) information network, suitable for running on a wide range of mainframe computers, is suggested and described. Time and expenditures required to implement the system are assessed. Two other possible methods of handling the data…

This report describes work concerned with the statistical evaluation of the output of MEDICO automatic indexing procedure. The statistical tests were designed to examine the validity of the assumptions which formed the bases of the indexing algorithms with primary emphasis on the algorithm development for the computation of weights and links. Some…

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…

The purpose of this document is to present a final description of the original MEDLARS system as it evolved through four years of operation. The system is described as it was functioning on January 1, 1968. Among the various system elements discussed are: (1) the input subsystem, including journal selection and coverage, Medical Subject Headings…

The broad objective of this investigation was to explore the potential and applicability of automatic methods for the indexing of drug-related information appearing in English natural language text and to find out what can be learned about automatic indexing in general from the experience. More specific objectives were the development,…

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…
