  • what do i mean by alternative forms of search?
  • what do i mean by alternative forms of search?
  • 199 millions pages that could help you!

  • completeness - including no answer
  • this is how ive been investigating it

    grounding it in mspace






  • google


  • better video?

  • but i suffered the result-availability problem
  • wanted a quick method - applied to prototyes - earlier design

    bit like stephann makri’s info behaviour work, but at a lower seeking only level.
  • 10 mins? earlier?

  • how does it support tactics at each of these points

  • and then it uses the models to infer support for certain types of users.






  • hit at 18mins ish


  • not going to go into history - ann knows the history
  • these have increasing ecological validity
  • but that doesnt tell you if its a good method for practitioners

    not ‘recommended’ - tried with very newbies


  • Cockton - its not measuring time - effort
    but makes you think about each feature and how it *could* be designed
    doesnt impose design - or design decisions
    ‘moves’ is just not a suitable measure for that
  • prof keith lloyd - director health sciences swansea

    analyse current UI
  • try to hit at 25 mins
  • that was a bit of a large vision into the future

    but in the mean time - it turns out that there’s still a lot we dont know about these exploratory conditions for example.

  • information need is probably either:

  • information need is probably either:



  • actually its still going
  • 30 mins or earlier


  • only 10 of the 12 words
  • left col - trouble?
    right col - children!
  • browsing - its very time-passing - open ended
    exploring - in a fixed space.

    faceted browsing?
  • hunting will provide us with a lot of insight into the information scarcity problem
  • searching - not associated with time - but often with ‘best’ or ‘optimal’ answers
    seeking - people (inc porn) and truth/god etc

    investigating was never really associated with love, happy, or goodness
    but the police
  • tried tweets with emoticons and a ‘lingo training set’
  • hunting often negative - perhaps lots of fails?
    browsing is neutral
    exploring is positive?
  • exploring is more positive, and browsing is very neutral
    browsing often to pass time
  • positive investigation == successful results?
    hunting, however, includes aptlist in the negative


  • retrieval is procedureal - perhaps the driving force of the IR community?
    ‘faceted browsing’ - browsing is actually just open ended passing time
    - chaining and random paths
    ES - understanding the breadth of something or checking them all
    Inv. - hidden dependancies (ben s)
