Evaluating interaction—what
is the right balance of user control and automatic processing when searching
for information?
Koenemann & Belkin
People did better and liked better the ‘penetrable’
interface for relevance feedback in the filtering task
See Muramatsu & Pratt
(SIGIR 01) for another study of making queries ‘transparent’ in 4 ways:
automatic Boolean operator; stop word removal, term suffix expansion, and term
order sensitivity---in this case, search task but look at user’s mental
models---not a quantitative comparison…poor mental models
Evaluating video skims: Christel et al. video retrieval and multiple features. 5 alternative system instances (baseline long
and short, new, best audio, full).
Integration of multiple features the best direction….implications for
giving users more control at the risk of overload.
