  1. research and innovationanalysing existing work Alan Dix STRUCTURE + DIVERGENCE = INNOVATION

  2. analysing existing work • structuring • themes, criteria, classification, etc. • understanding • why, why, why, why ... and why not? • deconstructing

  3. structuring • themes • criteria • classifications • taxonomies • multiple perspectives

  4. structure what • whole papers/documents • issues, topics within docs • things described • software/hardware systems • methods/techniques • application areas • observed behaviour

  5. themes • recurrent topics, issues, problemse.g. power usage in ubicom • how to find them? • you haved 2 minutes • tell a friend about the area • what would you say?

  6. criteria • mostly for things • software, methods, etc. • often binary • can it do X - yes or no • may be multi-choice • or qualitiative • does it support X - positive, negative, a bit     system A system B system C        

  7. the instant thesis • choose an area • gather literature • see what criteria each uses • apply criteria to all systems/methods

  8. classification and taxonomies • standard subject classification • problem specific classification • boundary cases • is a platypus a mammal, bird or reptile? • boundaries are constructs • hard cases tell us most

  9. finding classes - attributes • topic:genetic algorithms for fingerprint identification • possible classes: • recognition techniques: • genetic, statistical, annealing • recognition domains: • finger print, face, voice

  10. finding classes - comparisons • in what ways are they similar? • in what ways are they different? syuh how gtw hsio i ert ag ty ghn ty we ghty chdi qw oatyf wet dfla ght a syuh how gtw hsio i ert ag ty ghn ty we ghty chdi qw oatyf wet dfla ght a document B document A

  11. the easy way? • look in: • conference proceedings • books • special journal issues • workshops. . . what classifications do they use? ... steal them!

  12. hard cases • boundary cases • is a platypus a mammal, bird or reptile? • boundaries are constructs • outside classification • extend classes • hard cases tell us most

  13. similarity clear similarity obscured why multiple classifications? • taxonomy: • things • circles • red circles • yellow circles • squares • red squares • yellow squares

  14. colour red yellow circle shape square tell you in what ways things are similar and in what whay they differ multiple classification • shapes • circles • squares • colours • red • yellow

  15. an examplegroupware on the web D. Ramduny and A. Dix (1997). Why, What, Where, When: Architectures for Co-operative work on the WWW. in Proceedings of HCI'97, Eds. H. Thimbleby, B. O'Connaill and P. Thomas. Bristol, UK, Springer. pp. 283-301. • shared data - where is it? • local - on users’ own machines • remote - on a central server • but it moves • where is it stored? • where is it used?

  16. replicas caching client-server the data matrix usage remote local ? super- computers ASP local storage remote

  17. what about code? • applets a bit like cached data?

  18. download helper plug-in applet CGI etc. the code matrix usage/execution remote local ? SQL? local storage remote

  19. code and data • can be stored sep

  20. attribute spreading • topic: applications of technique X in area Y • look at:applications of technique X to other areas applications of other techniques to area Y technique Y other X area other
