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…

Discusses the potential of recent work in artificial intelligence, especially expert systems, for the development of more effective information retrieval systems. Highlights include the role of an expert bibliographic retrieval system and a prototype expert retrieval system, PROBIB-2, that uses MicroProlog to provide deductive reasoning…

Six experiments examined the problems third graders, sixth graders, and college students had in gaining access to episodic information while retrieving information from memory. Results suggested that conceptual access problems vary with grade and that elaboration of the representation of an episode facilitates access. (Author/SKC)

Describes significant attributes of expert systems, contrasts them to conventional computer systems, and provides an overview of the R1 expert system used by Digital Equipment Corporation (DEC) to put together operational systems that meet customers' requirements. Document handling, particularly pictures and images in documents, is also briefly…

Presents a model for the geometric analysis of the relationship between information queries and information systems retrieval, and demonstrates the utility of this analysis by its application to six conventional information retrieval similarity measures and a seventh spreading activation measure. (Author/CLB)

Describes in detail features of the IBM personal computer's components--computer, keyboard, monitor, printer, modem--and outlines specific choices for one searching machine that works well (system unit, disk drives, adapter boards, monitor, printer, modem, cables, options, supplies, software). Reasons to choose IBM personal computer for online…

This examination of online subject searching of personal names in four databases--PAIS, PsycINFO, Sociological Abstracts, and Social SciSearch--covers documentation and searching for personal names as descriptors, free-text and controlled vocabulary searching, recall and precision, identifier field, and online versus manual retrieval. Search…

Describes how operations on local inverted files are to be modified in order to use them in distributed information retrieval systems based on thesauri. The presented rules may be viewed as the logical approach in implementing a distributed retrieval system consisting of n local retrieval systems. (Author/MBR)

Acquaints information professionals with Digital Equipment Corporation's compact optical disk read-only-memory (CDROM) search and retrieval software and growing library of CDROM database publications (COMPENDEX, Chemical Abstracts Services). Highlights include MicroBASIS, boolean operators, range operators, word and phrase searching, proximity…

The overabundance of information resources and the inadequacy of current information retrieval methods are considered with special reference to the scholarly record of the health sciences. Both formal and informal means for finding information and for keeping abreast of new knowledge are reviewed, with practical suggestions for lightening the…

Describes basic strategy for cocitation searching, i.e., searching for any document citing at least two other specified documents, usually on same topic.
