Proposes a solution to the problem of loading repetitive bibliographic information in a microcomputer-based relational database management system. The alternative design described is based on a representational redundancy design and normalization theory. (12 references) (Author/CLB)

Demonstrates that hierarchical naming schemes--one with a single namespace and fixed root spread over all machines in a distributed system, and a second with total namespace composed of some aggregation of individual namespaces of each component system's filestores--can coexist in distributed computer systems. Combined system's design is…

Describes the general methodology of time and motion studies and reports the results of a study which used this methodology to compare digitization of images in a microcomputer environment with storage of images on microforms. (CLB)

Discusses data model role in an office filing facility, office data model requirements, and various modelling paradigms for office data modelling. Data model application to a typical collection of office data is presented, filing and retrieval operations are illustrated, and proposed research into other office data modelling aspects is outlined.…

Details a National Library of Canada project to produce a videodisc, show its value as a research tool, and demonstrate its viability as an information storage and retrieval medium. An overview and time sequence of the project, disc contents, resource materials for production, production and postproduction techniques, and project results are…

Describes experiences of Genealogical Library of Church of Jesus Christ of Latter-day Saints in using micrographics technology to preserve records of permanent value from throughout the world. Highlights include selecting and filming records processing and sorting film, cataloging and using microforms, and what the future holds. Three sources are…

Describes the Forest Science Data Bank that contains 2,400 data sets from over 350 existing ecological studies. Database features described include involvement of the scientific community; database documentation; data quality assurance; security; data access and retrieval; and data import/export flexibility. Appendices present the Quantitative…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Examines two primary roles played by natural language processing in storage and retrieval of information and outlines organization of natural language interface for data retrieval (question-answering system) and approaches being taken to text analysis. Research issues in computational linguistics and interactive knowledge acquisition are…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

Reviews the current status of satellite remote sensing data, including problems with efficient storage and rapid retrieval of the data, and appropriate computer graphics to process images. Areas of research concerned with overcoming these problems are described. (16 references) (CLB)

Examines novel computer filing systems which have particular application to office information storage and retrieval requirements. A variety of filing systems and their major characteristics are reviewed, ranging from network-based file servers to digital image storage and retrieval systems. Desirable characteristics of a modern electronic office…

The results of an examination of computer data formatting and data analysis strategies from two diverse second language projects and their implications for establishing standards are outlined in the form of suggested formatting conventions and analysis procedures. The formatting suggestions address the issues of distinguishing line types,…

Discusses types of sound-production equipment used for realization of interactive audio within computer assisted instruction (CAI) environments (speech synthesis systems, and speech/sound-recording, retrieval, and playback equipment); describes several authoring systems in which sound processing plays a predominant role; and presents an overview…

Zipfian laws for frequency distributions of word pairs and longer phrases are derived from text sample analysis. From crossing of Zipfian curves, it is deduced that number of multi-word phrases that occur frequently in text is surprisingly small, of same order of magnitude as number of individual word-types.
