Describes a hierarchical text database model and defines an algebra based on concordance lists. The algebra is presented as a theoretical model to define both a conceptual schema for the database and search protocols for database implementation. Several retrieval examples are included. (19 references) (MES)

Describes a conceptual design of a bibliographic retrieval system that enables more thorough control of bibliographic entities. The conceptual schema describes a database comprising two separate files of bibliographic description, one of intellectual works and the other of physical items. This model provides information about a work's association…

Discusses how imprecision and uncertainty are dealt with in the UFO (Uncertainty and Fuzziness in an Object-oriented) database model. Such information is expressed by means of possibility distributions, and modeled by means of the proposed concept of "role objects." The role objects model uncertain, tentative information about objects,…

Presents the conceptual design of a full-scale bibliographic database that includes bibliographic, authority, holdings, and classification data and is based on entity-relationship modeling. MARC format, AACR2 (Anglo-American Cataloging Rules) compatibility, and normalization and efficiency are discussed. (Author/LRW)

Presents a five-part framework for an information infrastructure: (1) aggregating (digital storage); (2) organizing (imposing higher-level structure); (3) using (retrieval processes); (4) tool building (designing and developing technologies for steps 1-3); and (5) policy making (metadata, selection criteria, use policies). Applies the framework to…

A hierarchical extension to the American National Standard for Bibliographic Information Interchange on Magnetic Tape is defined and described. The accommodation of the extension within the existing standard is discussed, modifications to the existing standard are proposed, and applications of the hierarchical format are presented. (21 references)…

Discusses the current status and future expectations of scientific and technical numeric databases. A bibliography provides resources for background readings, directories or listings of compilations, and subject specific discussions. Numeric database addresses and a summary of available databases are also provided. (CLB)

Outlines some of the major considerations in developing an image database system with an emphasis on continuous tone images and network-accessible multiuser databases. Topics include: definition/description of a digital image; matching technology to use; documentation/standards; access; image quality; software systems; scanners; and sources of…

Online bibliographic and network-based information systems are starting to blur the boundaries that separated print documents. Two concepts emerge as a consequence: the union record, an entity that combines multiple catalog records for a single bibliographic item; and an information dossier, a hypertext-like information object built by linking…

Presents an approach for dynamic database integration and query processing in the absence of information about attribute correspondences and global IDs. Defines different types of equivalence conditions for the construction of global IDs. Proposes a strategy based on ranked role-sets that makes use of an automated semantic integration procedure…

Describes the new concept of HYPERBASE and its relationship to classical hypermedia; a multimedia database retrieval system (SOPHIADOC) and its features in relation to the HYPERBASE concept; and an experimental use of SOPHIADOC to organize and scroll selected images on the "First Emperor of China" videodisk. Fifteen project publications…

Discusses various categories of software that can be applied to the development of in-house databases on microcomputers, and describes the use of a general purpose package with a procedural language to design a small indexing system called Revelation. The description covers data storage and maintenance, database design, file searching, and system…

Focuses primarily on design issues and practical concerns involved in creating World Wide Web documents for use within an organization. Concerns for those developing Web home pages are: learning HyperText Markup Language (HTML); defining customer group; allocating staff resources for maintenance of documents; providing feedback mechanism for…

Discusses the development of multiobject databases called large data constructs (LDC), which may contain images and recorded or synthesized voice as well as text. Virtual reality and cyberspace are discussed, selectivity and database content are examined, database management systems are described, and retrieval options are reviewed. (three…

Argues that effective hypermedia designs should meet four goals: (1) minimize clutter so that the document looks and feels simple to use; (2) create an image appropriate to the corporate sponsor and to the users' expectations; (3) provide ready access to stored information; (4) minimize the effort, technology, and resources needed.
