Abstract

This study investigated information retrieval from hypertext on the WWW. Significant main and interaction effects were found for both link density (number of links per display) and display format (in paragraphs or lists) on search performance. Low link densities displayed in list format produced the best overall results, in terms of search accuracy, search time, number of links explored, and search task prioritization. Lower densities affected user ability to prioritize search tasks and produced more accurate searches, while list displays positively affected all aspects of searching except task prioritization. The performance of novices and experts, in terms of their previous experience browsing hypertext on the WWW, was compared. Experts performed better, mostly because of their superior task prioritization

Abstract

The effect of link cues and link correspondences on search performance were investigated using a core hypertext document with external links to other resources on the WWW. Although subjects were to search for information in the core document, cues indicating links were to resources outside the search space did not affect performance. Subjects were not explicitly told the meaning of the cues and the duration of the search tasks was not sufficient for subjects to surmise their meaning. Correspondence of wording in search tasks to wording in links positively affected search efficiency, but not search accuracy. The implications of this finding and the need for further research are discussed
