The social sciences require multiple methods of analysis of information from complex data bases. Data bases have been constructed which contain hierarchical, spatial, and temporal associations among information elements. To provide effective processing capability an integrated approach was taken to facilitate storage and retrieval, statistical…

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. (AEF)

The Video PATSEARCH system consists of a microcomputer with a special keyboard and two display screens which accesses the PATSEARCH database of United States government patents on the Bibliographic Retrieval Services (BRS) search system. The microcomputer retrieves text from BRS and matching graphics from an analog optical videodisc. (Author/JJD)

This project comprises the second year's work of a 3-year research plan to develop computer programs, necessary data, and procedures for using the computer in a special field of musicology known as thematic indexing, and to explore the use of these techniques in other areas of music. During the second year, the research centered on three areas:…

Summarizes types of machine access available for users of Chemical Abstracts Online, a database which can accept and print out graphics images of chemical compounds. The use of Tektronix terminals, capabilities and limitations of other types of graphic termials and microcomputers, and estimated costs are noted. (EJS)

Evaluates TRADEMARKSCAN image retrieval using DIALOGLINK communications software. Factors discussed include TRADEMARKSCAN's composition, retrieval methods, file size, downloading and printing time and costs, and database applications. Software requirements and functions relevant to image retrieval are also discussed, and suggestions for…

Describes a unitized data system for a scientific database that stores descriptions of individual experimental steps as separate text-based subunits together with appropriate linking signals. Conversion of graphics into searchable text, use of natural language, and cost effectiveness are discussed. An example using a biology research paper is…

Recognizing the need for the development of a computer based information system which would handle remote sensing as well as conventional mapping data, the Bureau of Indian Affairs and the Bureau of Land Management contracted with Boeing Computer Services for the design and construction of a prototype Natural Resource Information System. The…

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)

Evaluates four map products currently available on CD-ROM in terms of hardware requirements, ease of installation, software, product content, documentation, cost, and instructional materials. Conclusions about the current status of maps on CD-ROM are offered and the desired characteristics for a perfect CD-ROM mapping product are identified. An…

Consumers and producers of educational software must make decisions about what kind of software to buy and create. Both groups must base these decisions on criteria that consider what it is important to learn in our technological era, what is workable, and what is currently practical and cost-effective. Five criteria that are central to these…

This paper discusses the present situation regarding national data bases (particularly, ERIC, EDSTAT II, and NEDL) in higher education. Topics include availability of data, methods of retrieval, and uses made of the retrieved data. Also discussed are trends which will greatly enhance the uses of data bases, including: (1) a computerized cataloging…

Introduces the Canadian Socio-Economic Information Management System (CANSIM), one of Canada's first computerized databases consisting entirely of Canadian data. System design, distribution network, services (time series, cross-classified system, summary data system), information retrieval, data presentation, and the graphic displays of Telichart…

Reports on the state of currently available digital storage and retrieval systems and describes in detail one-sided optical videodisc LaserData and the Mnemos system, which stores graphic images on microfiche discs. Video Patsearch, Matrox, Philips Megadoc, DEMAND, and Digital Recording Corporation's optical digital records and future videodisc…

Describes the latest modifications being made to OASIS, a front-end enhancement to the University of California's MELVYL online union catalog. Highlights include the X Windows interface; multiple database searching to act as an information network; Lisp implementation for flexible data representation; and OASIS commands and features to help…
