Buckland, Michael K.; And Others – Proceedings of the ASIS Mid-Year Meeting, 1992
Describes OASIS, a prototype adaptive online catalog implemented as a front end to the University of California MELVYL catalog. Topics addressed include the concept of adaptive retrieval systems, strategic search commands, feedback, prototyping using a front-end, the problem of excessive retrieval, commands to limit or increase search results, and…

Peer reviewedDenning, Rebecca; Smith, Philip J. – Information Technology and Libraries, 1994
Describes issues and advances in the design of appropriate inference engines and knowledge structures needed by commercially feasible intelligent intermediary systems for information retrieval. Issues associated with the design of interfaces to such functions are discussed in detail. Design principles for guiding implementation of these interfaces…

Peer reviewedLin, Xia; And Others – Journal of the American Society for Information Science, 1991
Discussion of search behavior in electronic environments focuses on the development of GRIP (Graphic Representor of Interaction Patterns), a graphing tool based on HyperCard that produces graphic representations of search patterns. Search state spaces are explained, and forms of data available from electronic searches are described. (34…

Peer reviewedFletcher, Liz – Electronic Library, 1993
Issues concerning the implementation of standard user interfaces for CD-ROMs are discussed, including differing perceptions of the ideal interface, graphical user interfaces, user needs, and the standard protocols. It is suggested users should be able to select from a variety of user interfaces on each CD-ROM. (EA)

Vigil, P. J. – 1988
Online searching is a complex problem solving task requiring the searcher to combine multiple sets into Boolean expressions. Since spatial ability has been correlated with problem solving tasks which involve abstract conceptual associations, this report argues that it is a significant factor in the information user's ability to both comprehend and…

Peer reviewedAl-Kharashi, Ibrahim A.; Evens, Martha W. – Journal of the American Society for Information Science, 1994
Describes experiments in Arabic information retrieval using 29 queries against a base of 355 bibliographic records. Using roots and stems as index terms worked better than words, and the root performed as well as or better than the stem at low recall levels and definitely better at high recall levels. (Contains 30 references.) (KRN)
