  • E-Learning on Social Semantic Information Sources

    1. 1. E-Learning on the Social Semantic Information Sources Sebastian Ryszard Kruk, Adam Gzella , Jarosław Dobrzański, Bill McDaniel and Tomasz Woroniecki adam.gzella @deri.org
    2. 2. Outline <ul><li>Problems and possible solutions </li></ul><ul><li>Introduction to SIOC, SSCF and JeromeDL </li></ul><ul><li>Our solution </li></ul><ul><li>Conclusions </li></ul>
    3. 3. „ John’s problems” – motivation scenario <ul><li>John - teacher in a distant course </li></ul><ul><li>Each lecture assisted with reading material </li></ul><ul><ul><li>Should be distributed week before lecture </li></ul></ul><ul><li>John wants to check if students read and understand </li></ul><ul><li>Gathered knowledge passed to the next year’s course. </li></ul><ul><li>He wants to utilise the power of Web/Web2.0 - most materials from: </li></ul><ul><ul><li>University library </li></ul></ul><ul><ul><li>Wikipedia </li></ul></ul><ul><ul><li>Online sources (like blogs) </li></ul></ul>
    4. 4. John’s solution <ul><li>Decide to use: </li></ul><ul><ul><li>Web/Web2.0 potential </li></ul></ul><ul><ul><li>Bookmarks sharing tool </li></ul></ul><ul><ul><li>Blog platform </li></ul></ul>
    5. 5. Is there a better way? <ul><li>Solution needs to be interoperable and universal </li></ul>Social Semantic Information Sources
    6. 6. SIOC – connecting online communities <ul><li>Simple but powerful </li></ul><ul><li>SIOC ontology – describes community metadata </li></ul><ul><li>Can be used for blogs, wikis and foras </li></ul><ul><li>Allows to: </li></ul><ul><ul><li>Cross-site queries </li></ul></ul><ul><ul><li>Topic related searches </li></ul></ul><ul><ul><li>Importing data from other sites </li></ul></ul><ul><ul><li>... and many other </li></ul></ul>
    7. 7. Sharing knowledge in community with SSCF <ul><li>SSCF – Social Semantic Collaborative Filtering </li></ul><ul><li>Gathering knowledge as a bookmarks </li></ul><ul><li>Bookmarks can be easily shared with friends </li></ul><ul><li>Users use friends bookmarks (possible domain expert) </li></ul><ul><li>Directories are well (semanticaly) described with wordNet and taxonomies </li></ul><ul><li>Fine grained access rights. </li></ul>
    8. 8. Sharing knowledge in community with SSCF
    9. 9. SSCF and SIOC <ul><li>SSCF supports SIOC data </li></ul><ul><li>User can bookmarks blogs post or even whole blogs </li></ul><ul><li>SIOC bookmarks are treated as standard SSCF resource. </li></ul>
    10. 10. JeromeDL – Semantic Digital Library <ul><li>Semantic Digital Library </li></ul><ul><ul><li>Digital Library with reach semantic annotations. </li></ul></ul><ul><ul><li>Advanced semantic search features. </li></ul></ul>
    11. 11. JeromeDL – Social Semantic Digital Library <ul><li>Social Semantic Digital Library </li></ul><ul><li>community oriented: </li></ul><ul><ul><li>Enriched with SSCF. </li></ul></ul><ul><ul><ul><li>Each user maintains private bookshelf with bookmarks to bibliographic resources </li></ul></ul></ul><ul><ul><li>Allows to the community to create knowledge (SIOC integration) </li></ul></ul><ul><ul><ul><li>Each book becomes a blog entry which can be commented </li></ul></ul></ul><ul><ul><ul><li>Data is exposed in SIOC format. </li></ul></ul></ul>
    12. 12. Our solution <ul><li>One tool that solves all the John’s problems </li></ul>
    13. 13. How it works for John <ul><li>Bookmarking interesting content and sharing it with students in right order. </li></ul><ul><li>Students sharing with each other </li></ul><ul><li>Students build new knowledge in JeromeDL </li></ul><ul><li>All the experience is available for next year students </li></ul>
    14. 14. What is happening JeromeDL creating knowledge SSCF sharing knowledge SIOC Exposing book comments In SIOC Support for SIOC enabled information
    15. 15. Ontology mapping <ul><li>SIOC with JeromeDL and SSCF: </li></ul><ul><ul><li>Support for SIOC ontology – RDF level. </li></ul></ul><ul><ul><li>Ontology alignment </li></ul></ul>
    16. 16. Time evaluation <ul><li>JeromeDL is much more efficient than 3 separate applications (digital library, blog engine, bookmarks sharing engine) </li></ul>
    17. 17. notitio.us <ul><li>SSCF is now part of notitio.us – semantic discovery, browsing and sharing </li></ul><ul><ul><li>Universal bookmarking system </li></ul></ul><ul><li>Notitio.us is equipped with Informal Knowledge Harvester </li></ul><ul><ul><li>Transforms informal knowledge into LOM and other formats. </li></ul></ul>
    18. 18. Conclusions <ul><li>Social Semantic Information Sources – JeromeDL and SSCF: </li></ul><ul><ul><li>Utilise Web 2.0 and Semantic Web potential </li></ul></ul><ul><ul><li>Can be very helpful in modern, web oriented e-Learning. </li></ul></ul>[email_address]
