    Opportunities for AI in Intelligent Web-based Technology-Supported Learning - Presentation Transcript

    1. Opportunities for AI in Intelligent Web-based Technology-Supported Learning Carsten Ullrich Jian Wang Ruimin Shen Frank Quosdorf
    2. Today’s Web: enormous potential for AI in technology supported learning.
    3. Today’s Web: enormous potential for AI in technology supported learning. But potential is still under-exploited
    4. Today’s Web: enormous potential for AI in technology supported learning. But potential is still under-exploited This talk: Trends
    5. Today’s Web: enormous potential for AI in technology supported learning. But potential is still under-exploited This talk: Trends Example
    6. Trends: Architecture of Assembly
    7. APIs
    8.  
    9.  
    10. Your own system
    11. RSS
    12. New Articles
    13. New Data
    14. Mash-ups Yahoo! Pipes http://www.flickr.com/photos/seeminglee/1950911618/
    15. Widgets
    16. Personal Learning Environments http://role-project.eu
    17.  
    18. Architecture of Assembly makes it easier to build complex services
    19. Architecture of Assembly adds to Web of documents a layer of reusable services
    20. Opportunities: -access to huge amounts of data useful for learning process; -analyze user generated content, e.g., to make estimations about their knowledge/competencies; -finding/combining services and combining to train specific skills.
    21. Trend: User-Centered Web
    22. Trend: User-Centered Web focuses on the individual using these documents and services
    23. Network of documents Network of people
    24. Live Streams Facebook Friendfeed
    25. Today: Silos
    26. OpenID: decentralized single-sign-on mechanism OAUTH: information exchange between services OpenSocial: APIs for common functionality for social applications
    27. Information about user: Attention Profiling Markup Language (APML) Location data: Google Gears, Firefox
    28. Amazing amounts of data about user available Opportunity: use this data for personalization
    29. Trend: Semantics
    30. Access to data no longer problem
    31. Access to data no longer problem Problematic: Find specific relevant piece of information
    32. Access to data no longer problem Problematic: Find specific relevant piece of information Combine data
    33. Semantic Web
    34. Linked Open Data Initiative Datasets include Wikipedia, DBLP, RKB Explorer, CIA World Fact Book, OpenCyc, …

    38. How to Get Semantics?
    39. Entity Extraction
      • The term "Web 2.0" is used to describe applications that distinguish themselves from previous generations of software by a number of principles. Existing work shows that Web 2.0 applications can be successfully exploited for technology-enhanced learning. However, in-depth analyses of the relationship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare.
    40. Entity Extraction
      • Gur grez "Jro 2.0" vf hfrq gb qrfpevor nccyvpngvbaf gung qvfgvathvfu gurzfryirf sebz cerivbhf trarengvbaf bs fbsgjner ol n ahzore bs cevapvcyrf.

      This is what it looks like to the machine!

      • Web 2.0
      • technology-supported learning
    43. Opportunities: - Semantic Content and Semantics for free enable amazing possibilities: improved quality of service, better categorization, recommendation, automatic linking with other resources, etc.
    44. Example: Totuba Toolkit
    45. - research workbench - bibliography manager - research network - support while writing research papers
      • context-sensitive further reading
      • related topics
      • drag&drop referencing
    47. Semantifying
      • The term "Web 2.0“...
      OpenCalais
      • Web 2.0
      • technology-supported learning
      DBPedia (others: Yago, Freebase, UMBEL)
      • http://dbpedia.org/resource/Web_2.0
      • http://dbpedia.org/resource/Technology-Enhanced_Learning
    48. Related Topics: Web_2.0 in DBPedia
      • skos:subject
        • dbpedia:Category:Buzzwords
        • dbpedia:Category:Branding
        • dbpedia:Category:Cloud_applications
        • dbpedia:Category:Internet_memes
        • dbpedia:Category:Social_Information_Processing
        • dbpedia:Category:World_Wide_Web
        • dbpedia:Category:Web_2.0
        • dbpedia:Category:Web_services
    49. Problems
    50. Most services: English only Services can become unavailable
    51. Lesson: To advance science, make research results available to other parties, as a Web service or open source.
    52. Conclusion
    53. Ground breaking services and data have now become basic commodity By building upon them, research in Technology-Enhanced Learning can tackle more meaningful problems
