Proposes an object-oriented conceptual data model tailored for organizing and representing basic map elements and their relationships, as well as operations of interest for the management of geographic data. Discussion includes both conceptual abstraction primitives (classification, generalization, and aggregation) and a spatial abstraction…

Shows how deductive data management techniques can be applied to the utilization of data value classifications in information retrieval. A representation of classifications which supports transitive computation is defined, and an operation-oriented deductive query language tailored for classification-based deductive information retrieval in fact…

Discusses categorization of MARC records, noting problems which arise because formats have not been defined as distinct sets of content designators. Bibliographic and authority record formats, merging of formats into single format, removal of inconsistencies, and criteria for identifying categories of records are considered. Thirty-one references…

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,…

Reports results of a study that examined Library of Congress topical subject headings and subdivisions in a large bibliographic database. Creation of a new machine-readable authority file of topical subdivisions and enhancements to the existing subject authority file are recommended to assist in assignment and validation of subdivided headings.…

It is increasingly important to design local biomedical databases with attention to naming and classification standards. In some cases, common nomenclature will not be suitable, having been designed for another purpose, but much will be useful. Development of standard nomenclature is a social responsibility in the electronic biomedical community.…

Illustrates the practical results of the five classification proposals presented in this volume. Each classification model has been applied to a common sample of colleges. Authors review the key implications of this collective exercise. Argues that local constructs demand a more sophisticated database at the national level. (Contains six tables.)…

Describes the development of a system to retrieve images for an international project that is producing a pictorial dictionary of classical mythology, the Lexicon Iconographicum Mythologiae Classicae. Applications to other types of information are discussed, two classification systems for Art History are described, and design principles for…

Papers on cataloging and national bibliography presented at the 1984 general conference of IFLA include: (1) "Pratiques et Problemes de Catalogage au Senegal" (Cataloging Practices and Problems in Senegal) (Marietou Diop Diongue, Senegal); (2) "The Consequences of New Technologies in Classification and Subject Cataloging in Third…

Explores the underlying concepts involved in the design of art scholarly databases and describes three systems definition projects currently in progress. The discussion covers the revisions of MARC formats and authority controls used in bibliographic information networks that might support an art scholarly database. (eight references) (CLB)

Reports on two empirical studies that examined the nature and causes of information management indeterminism in an online research environment. A knowledge-based design for alleviating indeterminism which contains a system-generated thesaurus and an inferencing engine is proposed. (Contains 63 references.) (JLB)

Examines usage scenarios for a database of descriptive information to access networked information resources such as online library catalogs, file archives, online journal article repositories, and information servers. Existing classification schemes and their usefulness for networked information resources are discussed. Specific data elements…

Describes the categories of available information management software, and provides guidelines for needs assessment, software selection, testing, and evaluation. The annotated bibliography cites general discussions and program reviews for the following types of software: file management, general database management, bibliographic management,…

This review of abstracting policies used by database producers focuses on the degree to which these policies incorporate criteria vital for acceptability of abstracts for free-text searching. Each topic in abstracting policy (abstract type, length, content, and language) is examined to consider its effect on retrieval. (MBR)

Discusses the role of visual images in the classification of art objects and the research needs of art historians in the context of the design of current printed resources and online databases in this discipline. The topics covered include the need for illustrated online reference works and appropriate indexing for access to bibliographic sources.…
