Presentation Transcript

  1. TOC • Open source • e-Learning vision • e-Learning framework • Conzilla a tool for conceptual browsing

  2. Open source and licensing • Science, innovation and evolution (discovery-replication) • Free as in free speech • Innovations from industry (ex medication or therapy?) • Grass root revolution • Buisness modell: charge for service • Cross pollination and reuse • GPL and the history of open source

  3. e-Learning Vision • Content managment • construction/annotation by teachers/learners • Techniques: portfolios, profiles, knowledge components and metadata • Knowledge navigation • Conceptual web and ontologies • Conceptmaps UML:ish • Experience-oriented environments • Lerner motivation via active environments (*) • Allows curiosity, expression and collaboration • Personal trust

  4. e-Learning Framework • Open flexible standards • RDF and semantic web (*) • IMS MetaData, content packaging and QTI. • A set of small applications • New functionalities will bring new tools • Collaborating tools can form an LMS • A conceptual web • UML as visually appealing layer of the semantical web • Tools for search and reuse of concepts/relations (*)

  5. e-Commerce approach • A methodology for domain modeling • Original domain model not available, refactoring necessary • UMM (UN/CEFACT) a standardized methodology that uses UML (*) • A mediator that • Understands several schemas • Easily extendable via modeling and mappings (*) • Transfers semantics (both statics and dynamics) • Keeps the system in a legal state

  6. Research issues • Semantic/Conceptual web and their presentations • UML(2.0) in RDF (*) • Metadata, content packaging and other standards in RDF • Semantic interoperability (*) • Transformation schemas • Temporal aspects • Query and filter schema • Methodology for integration of ontologies

  7. Practical • Amount of work to be done • We cooperate with both academia and industry • We are (hopefully) on the right track • Open source and evolution • Will anyone use it? • MIT OCW (Open CourseWare) initiative • National agency for education, National initiative for information structures • Large interest from a long range of parties.
