| Abstract: | The purpose of this study is to carry out a direct comparison of a hypertext-based bibliographic retrieval system with a traditional Boolean-based retrieval system, each using the same database. Novice and experienced searchers were assigned to either a prototype hypertext system called HyperLynx or to a traditional Boolean system and were asked to perform a set of search tasks. The study revealed that the Boolean system performed better than the hypertext system for search tasks with a large number of relevant items. Searcher experience level did not play a significant role for either system. Findings of the study have implications for the design of future information retrieval systems that take advantage of the best features of both approaches for more effective and efficient retrieval of highly structured databases. |
