This paper is focused on a central aspect in the design of a planned digital library for human movement, i.e. on the aspect of representation and recognition of human activity from video data. The method of representation is important since it has a major impact on the design of all the other building blocks of the system such as the user…

Describes the design and implementation of a prototype visualization system, AuthorLink, to enhance author searching. AuthorLink is based on author co-citation analysis and visualization mapping algorithms. AuthorLink produces interactive author maps in real time from a database of 1.26 million records supplied by the Institute for Scientific…

Explains how the Directory Service (CCITT X.500/ISO 9594) became an international standard in response to the difficulties of keeping data on information network users current and accessible. Uses of X.500 are described, a technical overview is provided, its functions and protocols are assessed, and directory projects and products are discussed.…

Management of heterogeneous networks is complicated by the persistence of proprietary management schemes. The need for integration of network management capabilities is pressing. The International Organization for Standardization is developing standards for managing networks as part of the Open Systems Interconnection (OSI) effort. OSI management…

Reviews some of the projects and organizations concerned with promoting conformance and interoperability testing of Open Systems Interconnection (OSI) products and describes OSI products available from computer manufacturers and vendors. A list of references includes 57 articles that mention specific vendors and 11 general articles about OSI…

Describes the design of an expert system developed using VP-Expert for document delivery decision making in a law library. Presents methods used in knowledge acquisition and knowledge representation after a brief review of the literature on expert system use in libraries. An appendix includes the rules of the expert system. (Author/AEF)

Describes the use of the Z39.50 information retrieval protocol as the basis for Infocal, a read-only, client/server-based campus information system. Technical considerations in adapting the protocol to nonbibliographic data, including semantic modules, dynamic attribute sets, and dynamic record syntax, are described in detail. (Contains 11…

Describes the development and implementation of a full-text image retrieval system at the Boeing Commercial Airplane Group. The conversion of card formats to a microcomputer-based system using HyperCard is described; the online system architecture is explained; and future plans are discussed, including conversion to digital images. (LRW)

Describes a study which investigated the general patterns and level of applicability of Anglo American Cataloging Rules (AACR2). It is suggested that designers and revisers of AACR2 should reduce the number of rules of very limited applicability levels and enhance the rule contents for application domains to expand the usefulness of AACR2. (SD)

Describes enhancements made to a hypertext information retrieval system at the National Energy Research Supercomputer Center (NERSC) called DFT (Document, Find, and Theseus). The enrichment of DFT's entry vocabulary is described, DFT and other hypertext systems are compared, and problems that occur due to the need for frequent updates are…

Describes a method of full-text scanning for matches in a large dictionary. The method is suitable for selective dissemination of information systems, accommodating large dictionaries and typical digital data rates. It can be implemented on a single commercially-available board hosted by a personal computer or entirely in software. (Author/AEF)

Suggests an alternative document representation method based on "exemplary documents," those that describe or exhibit the intellectual structure of a particular field of interest. Exemplary documents provide both an indexing vocabulary for that area and a narrative context in which the indexing terms have a clearer meaning. It is much…

Presents an overview of the ways in which user/system interaction in interactive information-retrieval (IR) systems has been treated in IR research and practice over the years. Describes the characteristics of a number of IR systems, as well as proposals for IR systems, in light of challenges set for by John Bennett in 1971. Contains 82…

Reviews the characteristics of the Cheshire II system that is being used to implement full-text and fielded searching of bibliographic information for the University of California Berkeley Digital Library Initiative. Examines its performance when applied to a collection of large full-text documents in the TREC Interactive Retrieval Track and its…

Suggests that the money spent ($100 billion) to fix the Y2K bug in the United States resulted in improved campus computer systems. Reports from campuses around the country indicate that both mainframe and desktop systems experienced fewer problems than expected. (DB)
