Describes work in progress at the Smithsonian Institution in developing a system to understand and articulate the information needed to support collection related functions. The discussion covers the data modeling methodology used and the advantages of this methodology in structuring museum collections information. (one reference) (CLB)

Describes an alternative method for indexing images in an image database. The method consists of manually indexing a selected reference image, and then using retrieval by graphical content to automatically transfer the manually assigned index terms from the reference image to the images to be indexed.

A meeting was held to explore critical issues and problems related to subject access to online bibliographic records of monographic literature. The 23 researchers, practitioners, and policymakers who attended represented national and research libraries, bibliographic utilities, database vendors, library schools, indexing and abstracting services,…

This examination of abstracting-indexing services for the field of history focuses on Historical Abstracts (HA) and America--History and Life (AHL), and their relationship to the American Bibliographical Center's Subject Profile Index (ABC-SPIndex). The history, scope, selection criteria, and classification arrangements of the two databases are…

THE BACKGROUND, OPERATIONAL, AND PROCEDURAL EVENTS LEADING TO AND INCLUDED IN THE BUILDING OF THE "THESAURUS OF ENGINEERING AND SCIENTIFIC TERMS" ARE DISCUSSED. THE WORK WAS PERFORMED BY THE OFFICE OF NAVAL RESEARCH, AT THE REQUEST OF THE DIRECTOR, DEFENSE RESEARCH AND ENGINEERING, UNDER A SPECIALLY ESTABLISHED TASK NAMED PROJECT LEX.…

ONE OF THE PROBLEMS IN INFORMATION STORAGE AND RETRIEVAL SYSTEMS OF TECHNICAL DOCUMENTS IS THE INTERPRETATION OF WORDS USED TO INDEX DOCUMENTS. SEMANTIC TOOLS, DEFINED AS CHANNELS FOR THE COMMUNICATION OF WORD MEANINGS BETWEEN TECHNICAL EXPERTS, DOCUMENT INDEXERS, AND SEARCHERS, PROVIDE ONE METHOD OF DEALING WITH THE PROBLEM OF MULTIPLE…

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…

To support studies in automatic indexing, classification and extracting, a general purpose frequency program was developed to further theoretical and practical understanding of text word distributions. While the program is primarily designed for counting strings of character-oriented data, it can be used without change for counting any items which…

A fundamental problem in the two broad approaches to indexing in the social sciences--providing structure using preferred terms, cross references, and groupings of sets of materials, or compiling a concordance of an author's terms based on occurrence, leaving users free to impose their own structure--is that different indexers and users focus on…

The report is concerned with the implementation of an on-line information storage and retrieval system for the Rome Air Development Center. This system is to incorporate techniques of automatic document classification for a large document collection in an interactive environment. Following a review of the system design, the implementation of the…

The U.S. Army Aeromedical Research Laboratory (USAARL) is often required to make specialized measurements and perform applied research in aircraft-related areas of environmental medicine. Rapid access to the periodical literature is essential for the completion of many of these projects. A growing file of reprints from the periodical literature is…

The paper reports on a series of programs that have been developed at the Moore School to process data-bases, consisting of textual items, and to index and arrange the data items in accordance with an automatically generated classification system. The programs produce the directories and the rearranged data-base on microfilm, where it may be…

An investigation was made of the Universal Decimal Classification (UDC) as an indexing language for computer retrieval. Problem areas were identified (notation, schedules, application), new developments reviewed (combining precedence devices, subject analysis matrices, guidelines for schedule revision, pilot schedules, parenthesis-free notation…

Reaction formation was studied by Sigmund Freud. This defense mechanism may be related to repression, substitution, reversal, and compensation (or over-compensation). Alfred Adler considered compensation a basic process in his individual psychology. Anna Freud discussed some defense mechanisms, and Bibring, Dwyer, Huntington, and Valenstein…

This review of the 1986 literature on subject access covers: (1) general works; (2) organization and history; (3) classification systems; (4) classification theory and method; (5) Library of Congress Subject Headings (LCSH); (6) authority control through LCSH; (7) subject searching through LC-based, assigned subject headings; and (8) other subject…
