Transcript

  • 1. The SIOC Project: Semantically-Interlinked Online Communities John Breslin, Uldis Bojars
  • 2. What is SIOC?
    • An effort to discover how we can create and establish ontologies on the Semantic Web
    • Aim of the SIOC ontology is to address interoperability issues on the (Social) Web
    • Adopted in a framework of 50 applications or modules deployed on over 400 sites
  • 3. Enabling SSIS
  • 4. Motivation
    • Need to understand how to create and establish ontologies on the Web:
      • Social engineering is required
    • Disconnected sites on the Social Web require ontologies for interoperation:
      • Lots of social data, inherent semantics (chicken and egg)
      • Potential for high impact
    • In parallel, lack of integration between social software and other systems in enterprise intranets
  • 5.  
  • 6.  
  • 7. The SIOC solution
    • Develop an ontology of terms for representing rich data from the Social Web
    • Create a food chain for producing, collecting and consuming SIOC data
    • As well dissemination via papers about SIOC, provide docs and examples at sioc-project.org
    • SIOC aims to enrich the Web infrastructure:
      • During the next upgrade cycle, gigabytes of community data become available!
  • 8. 1. The SIOC ontology
    • The main classes and properties are:
  • 9. Interlinking with FOAF and SKOS
  • 10. Challenges that had to be overcome
    • Earlier efforts failed to generate the momentum required to achieve successful deployment
    • If you build it, they won’t necessarily come
    • We needed some “social engineering” to facilitate the adoption of a de-facto standard ontology:
      • Model
      • Agree
      • Deploy
      • Re-model
  • 11. 2. The SIOC food chain
  • 12. Producing SIOC data
    • Over 20 a pplications for p roducing SIOC d ata :
      • Many are f ree and o pen s ource
      • Blogs and forums: WordPress, phpBB, Drupal, b2evolution
      • “ Legacy” applications: m ailing lists, IRC
      • New media: Twitter, Jaiku , Facebook, Flickr
    • APIs for those who may wish to make their own producers:
      • PHP, Perl, Java, Ruby on Rails
  • 13. Using SIOC and FOAF to represent portable data
  • 14. Collect SIOC from various sources
  • 15. Consuming SIOC via a Sindice API
  • 16. Consuming SIOC via Exhibit
  • 17. 3. Dissemination
  • 18. Publications and other outputs
    • ~25 SIOC-related publications from DERI, including the Journal of Web Semantics, IEEE Intelligent Systems, IEEE Internet Computing, European Semantic Web Conference (2)…
        • 139 papers from Google Scholar matching “sioc semantic”
    • SIOC-related tutorials at WWW2006, WWW2008, SemTech 2008 (next week); workshop at ISWC2008
    • W3C Member Submission of the SIOC ontology:
        • http://www.w3.org/Submission/2007/02/
    • Media interviews about SIOC for PC World / WashingtonPost.com, SiIicon Republic, IEEE Computer, SemanticWeb.com, etc.
  • 19.  
  • 20. Quotes about SIOC
    • “ I […] think the concept is HOT” – Robert Douglass, Drupal Developer
    • “ It just dawned on me that the burgeoning SIOC-o-sphere (online communities exporting and exposing content via SIOC Ontology) is actually: Blogosphere 2.0” – Kingsley Idehen, Founder and CEO of OpenLink Software
    • “ SIOC has the potential to become one of the foundational vocabularies that make Semantic Web applications useful” – Ivan Herman, W3C / ERCIM
    • “ A project that started back in 2000 called Friend-of-a-Friend (FOAF) represents relationships between people, as well as basic contact details. SIOC does this for groups: it extends the FOAF idea to being able to talk about whole groups of people. I am excited about SIOC because you can use that information to determine trust, to let people in.” – Tim Berners-Lee, Creator of the World Wide Web
  • 21. SIOC metrics
    • SIOC documents at PTSW:
      • 107759 (SIOC)

    • 42911 hits in Swoogle
    • Sites producing SIOC data:
      • 373 listed in PTSW pings
    • SIOC ontology is ranked 4 th and SIOC Types module 5 th in 500 ontologies at PTSW
    • SIOC developer mailing list:
      • 200 members
      • 900 posts
  • 22. BSCW and BC
