A series of experiments was performed to investigate the effectiveness and utility of automatically classifying documents through the use of multiple discriminant functions. Classification is accomplished by computing the distance from the mean vector of each category to the vector of observed frequencies of a document and assigning the document…

Against a background of widespread interest in national information systems, the American Institute of Physics is developing such a system for physics. This program pivots on the design of a new classification system for physics which is to be used, in conjunction with free-language index terms, for the intellectual organization of the physics…

Subjects covered in this bibliography include manual, mechanized and automated techniques, evaluation of systems, standards, storage and retrieval systems, research, vocabularies, author participation, permuted title indexing, citation indexing, and specialized indexing requirements, i.e. chemistry, medicine, patents, engineering drawing, and…

THE BACKGROUND, OBJECTIVES, AND ACCOMPLISHMENTS OF THE PROJECT ARE REVIEWED BRIEFLY. SPECIFIC AREAS DISCUSSED ARE ENGLISH-LANGUAGE UDC SCHEDULES, A COMPUTER-BASED UDC FILE MANAGEMENT SYSTEM, DATA BASES FOR RETRIEVAL EXPERIMENTS, AND RETRIEVAL SYSTEM EVALUATION. THE CONCLUSIONS DEAL WITH THE USEFULNESS OF THE UDC FOR MECHANIZED RETRIEVAL SYSTEMS,…

SEARCH STRATEGIES WHICH CAN BE CONTINUOUSLY MODIFIED WERE DEVELOPED FOR COORDINATE SEARCHING SYSTEMS. USING THE FILES OF THE NASA TECHNOLOGY UTILIZATION PROGRAM AT THE KNOWLEDGE AVAILABILITY SYSTEMS CENTER, UNIVERSITY OF PITTSBURGH, A STUDY WAS CONDUCTED OF THE RETRIEVAL OF RELEVANT DOCUMENTS BY BOTH MANUAL AND MACHINE METHODS FOR FIVE QUESTIONS…

The identification of information elements can provide an important tool for the systematic development of an information system design. A state-of-the-art survey reveals mounting recognition and interest in the problem, a considerable history of prior efforts, but no well-defined methodology. A study in the context of a national information…

Discusses theoretical and practical progress made in the classification of information for retrieval in the last 20 years and suggests alternatives to the Dewey Decimal and Library of Congress classification systems. (JVP)

This document describes the major organizational components of the Educational Resources Information Center (ERIC) system, the interactions between those components, and the major products and services provided by those components. (WTB)

Subject indexing in ERIC is performed by subject specialists across 16 geographically dispersed ERIC Clearinghouses, each responsible for a different niche or aspect of educational information. This phenomenon, combined with the broadness of the education field and variability of terminology therein, has led to the development at the…

This loose-leaf manual provides the detailed rules, guidelines, and examples to be used by the components of the Educational Resources Information Center (ERIC) Network in acquiring and selecting documents and in processing them (i.e., cataloging, indexing, abstracting) for input to the ERIC computer system and subsequent announcement in…

With a view to improving information systems and services in Eastern, Central, and Southern Africa, this Information Systems Workshop was organized by the East and Southern African Management Institute (ESAMI) with assistance from the Coordinating Centre for Regional Information Training (CRIT). The specific aims of the workshop were to acquaint…

A document storage and retrieval system for the library of the Materials and Research Department of the California Division of Highways is described. The system was designed and installed as part of a research project whose objectives were to evaluate a concept-coordinated document retrieval and storage system for internally and externally…

Describes a model for the standardization of names in bibliographic databases. Discusses a prototype that was developed to demonstrate feasibility of the model, and investigates the impact of implementing the model. Findings suggested that the new model will revolutionize name authority control and that the prototype verifies the technical…

THIS REPORT IS A BRIEF REVIEW OF RESULTS OF AN EXPERIMENT TO DETERMINE THE INFORMATION RETRIEVAL EFFICIENCY OF A MANUAL SPECIALIZED INFORMATION SYSTEM BASED ON 700,000 DOCUMENTS IN THE FIELDS OF ENDOCRINOLOGY, STRESS, MAST CELLS, AND ANAPHYLACTOID REACTIONS. THE SYSTEM RECEIVES 30,000 PUBLICATIONS ANNUALLY. DETAILED INFORMATION IS REPRESENTED BY…
