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

Enabling SSIS

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

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

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!

Interlinking with FOAF and SKOS

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

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
