Abstract

We compared the effectiveness of two versions of the NetBook data model for nonlinear text-one with links and one without. Users who accessed information through specifications based on properties and values alone performed better than users who employed such specifications as well as hypertext links. Protocol analysis revealed that hypertext links were useful when a subject's specifications were unspecific but correct. However, hypertext could rarely compensate for inaccurate specifications. Design recommendations are included.
