What does it mean to search hypertext?
Nelson ‘67 explicitly dissociates hypertext from document retrieval
Nice for browsing, but bad for fact retrieval?
A contrast: planning vs. browsing
- Simply follow links
- less effort
- learn by serendipity (maybe)
- Formulate query and show pages of hits as in standard IR
- requires planning
- systems assumed a professional intermediary
Hypertext allows for a novel interaction between navigating links and formulating queries
