CoPe_it! ODET 2010 Presentation

  1. 1. http://copeit.cti.gr/ Nikos Karacapilidis Research Academic Computer Technology Institute & University of Patras, Greece
  2. 2. Requirements and challenges <ul><li>The Palette project (FP6) – 12 CoPs </li></ul><ul><li>Major issues </li></ul><ul><ul><li>Cognitive overhead and management of information overload </li></ul></ul><ul><ul><li>Different collaboration modes </li></ul></ul><ul><ul><li>Expression of tacit knowledge </li></ul></ul><ul><ul><li>Integration of legacy resources </li></ul></ul><ul><ul><li>Data processing and decision making support </li></ul></ul>
  3. 3. Our approach (i) <ul><li>Web based Argumentative Collaboration environment to support collective knowledge building </li></ul><ul><ul><li>Semi-synchronous collaboration </li></ul></ul><ul><li>Basic goals </li></ul><ul><ul><li>An integrated consideration of formalization, visualization and reasoning issues </li></ul></ul><ul><ul><li>Allow formality to vary during the collaboration session (addressing different collaboration stages) </li></ul></ul><ul><li>Incremental formalization of collaboration </li></ul><ul><ul><li>Permitting a stepwise and controlled evolution of the collaboration space </li></ul></ul>
  4. 4. Our approach (ii) <ul><li>Conceptual architecture </li></ul><ul><ul><li>Based on projections </li></ul></ul><ul><ul><ul><li>A representation of the argumentative collaboration in some evolution stage. </li></ul></ul></ul><ul><ul><ul><ul><li>The same collaboration can have different representations </li></ul></ul></ul></ul><ul><ul><ul><li>Each projection provides different abstractions and allows different operations </li></ul></ul></ul><ul><ul><ul><ul><li>Supports a level of formality (solves the problems of a particular collaboration stage) </li></ul></ul></ul></ul><ul><ul><ul><li>Ability to switch between projections  change level of formality </li></ul></ul></ul>
  5. 5. collection & sharing of collaboration items interrelation & evolution of collaboration items informal / semiformal argumentation exploitation of legacy resources semantic annotation of collaboration items informal / semiformal aggregation of collaboration items formal exploitation of collaboration items patterns formal argumentation and reasoning mechanisms Our approach (iii) Informal Formal collaboration space projection 2 toolset 2 projection n toolset n … projection 1 toolset 1 Formality
  6. 6. Early instance of the collaboration <ul><li>desktop metaphor </li></ul><ul><li>visual cues </li></ul><ul><li>exploitation of legacy resources </li></ul><ul><li>user & role modeling </li></ul><ul><li>human interpretable </li></ul>informal projection
  7. 7. Another instance of the collaboration
  8. 8. Filtered view: automatically arranging items
  9. 9. formal projection <ul><li>decision making support </li></ul><ul><li>reasoning & scoring mechanisms </li></ul><ul><li>switching between projections </li></ul>
