SIOC (Semantically-Interlinked Online Communities) is an ontology for representing data from online communities on the Semantic Web. It aims to address interoperability issues by standardizing the representation of social data. The SIOC ontology has been adopted by over 50 applications deployed across 400 sites. It establishes a "food chain" for producing, collecting, and consuming social data in order to enrich the Web infrastructure.
![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](https://image.slidesharecdn.com/20080522asanfranciscoradarnetworks-1215782127243154-9/85/The-SIOC-Project-20-320.jpg)
The SIOC Project
- 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
- 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
- 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.
