  1. Mark Dunlop My view of Information Retrieval Current research topics Some future directions

  2. My view of basic IR http://www.dcs.gla.ac.uk/~mark/talks/

  3. Current research topics • IR oriented • Using additional information to enhance queries • Expected Search Duration evaluation model • Evaluation in general • HCI oriented • Usability of mobile computing devices http://www.dcs.gla.ac.uk/~mark/talks/

  4. Enhancing queries • Use of contextual info • My thesis • Vassillis Harmandas’s WIRE system • Theodore Dalamagas’s HIM system • Cross session/historic info • Robert Villa’s PhD http://www.dcs.gla.ac.uk/~mark/talks/

  5. Simple thesis model http://www.dcs.gla.ac.uk/~mark/talks/

  6. WIRE http://www.dcs.gla.ac.uk/~mark/talks/

  7. HIM http://www.dcs.gla.ac.uk/~mark/talks/

  8. 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” http://www.dcs.gla.ac.uk/~mark/talks/

  9. ERMIA model of Alta Vista http://www.dcs.gla.ac.uk/~mark/talks/

  10. Sample ESD graph http://www.dcs.gla.ac.uk/~mark/talks/

  11. Evaluation • Mira (CEU funded working group) • Organisation of workshops and conference • Experiments with Steve Draper on testing different classic HCI evaluation approaches • Gauguin • Potential follow on bid for EU network http://www.dcs.gla.ac.uk/~mark/talks/

  12. Mobile Computing 1 • Paraglide - newly funded EPSRC project • Palm held anaesthesia record assistant • Design & evaluation of gestural interfaces • Use of contextual analysis to limit input space • With Phil Gray and Martin Gardner • Ramblin Gumption - moving understanding • Developing grant bid on novel input techniques for “limited display devices” • With Phil Gray and Steve Brewster http://www.dcs.gla.ac.uk/~mark/talks/

  13. Mobile Computing 2 • Undergraduate projects • Alphasliders • Starfield displays • Dictionary aided text entry on a mobile phone • Mobile workshops • Glasgow 98 • INTERACT 99 http://www.dcs.gla.ac.uk/~mark/talks/

  14. 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 IR • Embedding IR in devices http://www.dcs.gla.ac.uk/~mark/talks/
