Peer reviewedClementini, Eliseo; Di Felice, Paolino – Journal of the American Society for Information Science, 1994
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…

Arnold, Stephen E. – Microcomputers for Information Management, 1990
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…

Peer reviewedBearman, David – Library Trends, 1988
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)

Peer reviewedSavoy, Jacques – Information Processing and Management, 1994
Proposes a new learning algorithm to improve the retrieval effectiveness of the search system used in the hypertext environment using an extended Boolean model with links to improve the ranking of retrieved items. Highlights include the basic retrieval scheme, the learning scheme, and a review of basic probabilistic retrieval models. (Contains 32…

Peer reviewedNeuman, Delia – Educational Technology, Research and Development, 1993
This article reports results of a case study of text-based online and CD-ROM databases that identified design characteristics that are important to high school students' use for higher-level learning as well as for information access and retrieval. Implications for the design of databases are suggested. (Contains 62 references.) (LRW)
