  1. 1. Automated Course Composition based on Semantic Knowledge Filip Maciej Czaja Filip Maciej Czaja [email_address] SemInf, 14.03.2007
  2. 2. Presentation outline <ul><li>Current vs. future e-learning systems </li></ul><ul><li>Workflow patterns & composition issues basing on Didaskon project </li></ul><ul><li>Future work </li></ul>
  3. 3. Motivation <ul><li>Current e-learning systems: </li></ul><ul><li>Predefined courses tailored for a generic student on one of the generic levels of skills/knowledge. </li></ul><ul><li>Do not take into account user specific conditions. </li></ul><ul><li>Information is repeated in many courses. </li></ul><ul><li>Potentially interesting information might not be cross-referenced between courses. </li></ul>
