Expected Search Duration
Aims to predict time to complete stereotypical search tasks add user interface aspects to the test-collection
(TC) evaluation approach
Built on combining expanded versions of Cooper’s Expected Search Length TC measure Green and Benyon’s ERMIA interface modelling
Future: test predictions and “package”

Additional future directions
Developing an encompassing model of contextual information Personal info/contexts/descriptions? Transparent use of context info (e.g. open documents)? Robert’s historical info?
Bringing authors into the evaluation process Applying HCI theories in IREmbedding IR in devices
