Title

Navigation in hyperspace : an evaluation of the effects of navigational tools and subject matter expertise on browsing and information retrieval in hypertext

Source

Interacting with computers. 10(1998) no.2, S.129-142

Abstract

Examines the effectiveness of a map and a textual contents list on the navigation performance of subjects with and without prior knowledge of the text topic in hypertext. Subjects used the document to answer 10 questions. the results showed that performance in the map condition was superior to that of the contents list condition, which in turn was superior to that of the hypertext only condition. Knowledgeable subjects performed better than non-knowledgeable subjects, except in the map condition where their performance was equivalent. the results show that non-knowledgeable users tend to rely more heavily on navigational aids than knowledgeable users, and that aids were used primarily during browsing and information retrieval in hypertext
