Can be linked via semantics

Social Semantic Web

Two-way street: semantic web can help social web, vice versa • Can Use semantic web to describe people,

content objects and the connections that bind them all together so that social sites can interoperate via semantics

• In the other direction, object-centered social websites can serve as rich social data sources for semantic applications

Semantically-Interlinked Online Communities (SIOC)

• Goal of the SIOC ontology is to address interoperability issues on the Social Web – sioc-project.org – W3c member submission in 2007

– SIOC has been adopted in a framework of 100 applications or modules deployed on hundreds of sites

– Web 2.0, enterprise info integ, HCLS, e-gov

Some applications using sioc

RDFA in drupal 7

• Drupal cms used by 2 percent of all sites

• drupal 7 release has semantic web support built-in

• Rdfa (sioc, foaf, dublin core, skos) data for blog posts, forums, etc.

• Video at www.semantic-drupal.com

Sioc can be used to...

• ...provide a layer of rdfa metadata from a social website, e.g. to enhance search results >> superceded by schema.org?

• ...get a Complete representation/xml dump of a social website (export, import)

• ...be a native format for social websites

• ...do other stuff; just imagine!

HOW MUCH SIOC DATA IS OUT THERE?

So…

WE HAVE MADE ALL THIS DATA, NOW DREAM ABOUT THE USEFUL APPLICATIONS!

Make A giant brain(-storm!)

• Distributed conversation navigator • Comment search engine for the a in q&a

• Expert finding applications galore ...

– Be cognisant of the huge growth in social semantic web data being provided by the adopters of schema.org and its new terms

Sioc-related initiatives

Brainstorm ontology

Sioc for e-participation

• Rdf-powered e-participation platform

– To be Based on wordpress+native rdf store

• Will Allow citizen discussions to be linked to relevant linked data from public sites, governments, etc.

– adds context • Work in progress

– Galwaytf.com

Citizen sensors

•  Model commons sensors on Android phones •  Attach sensor information to microblog posts

automatically or with user approval –  Using Twitter annotations format and/or RDF (ssn +

sioc + sioc types and sensors modules): • sioct:MicroblogPost siocs:has_sensor_data

ssn:Observationvalue
