Title
Enhancing a new design for subject access to online catalogs
Source
Library hi tech. 14(1996) no.1, S.87-109
Year

Abstract
Search trees are sets of paths with branches or choices that enable systems to carry out the most sensible search approaches at each stage of searches. Report results of a research project, undertaken at Michigan University, which aimed to identify characteristics of the most difficult user queries and recommend enhancements to the new subject searching design to enable it to produce useful retrievals in response to the wide variety of queries users pose to online catalogues. Online catalogues governed by search trees are more effective than the users themselves in selecting subject searching approaches and the enhanced search trees described and tested enlist subject searching approaches that are not typical of the functionality of operational online catalogues. Concludes that design and development is required to upgrade existing online catalogues with search trees and new subject searching functionality to be successful in responding with useful retrievals to the most difficult user queries
