Title
Effectiveness of information retrieval systems used in a hypertext environment
Source
Hypermedia. 5(1993) no.1, S.23-46
Year
1993
Abstract
In most hypertext systems, information retrieval techniques emphasize browsing or navigational methods which are not thorough enough to find all relevant material, especially when the number of nodes and/or links becomes very large. Reviews the main query-based search techniques currently used in hypertext environments. Explains the experimental methodology. Concentrates on the retrieval effectiveness of these retrieval strategies. Considers ways of improving search effectiveness
