It's the social objects we create…
• Discussions • Bookmarks
• Annotations • Microblogs
• Multimedia
…that connect us to other people
Social media sites are like data silos

Many isolated communities of users and their data

Need ways to connect these islands

Allowing users to easily move from one to another

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

Foaf (friend of a friend)
What's foaf?
• An ontology for describing people and the relationships that exist between them: – foaf-project.org – Identity, personal profiles, social networks
– Can integrate with other SW vocabularies
– Used on LiveJournal, MyOpera, identi.ca, MyBlogLog, hi5, Fotothing, Videntity, FriendFeed, Ecademy, Typepad

SIOC, pronounced shock

Semantically-Interlinked Online Communities (SIOC)
• Goal of the SIOC ontology is to address interoperability issues on the Social Web
• sioc-project.org • SIOC has been adopted in a framework of
50 applications or modules deployed on over 400 sites
• Web 2.0, enterprise information integration, HCLS, e-government
Some of the SIOC core ontology classes and properties

From last October
RDFA (Sioc, FOAF) in drupal 7
• Drupal is a cms used by various sites: – whitehouse.gov, warnerbrosrecords.com,
uk.sun.com, motogp.com...
• Five Alpha versions of drupal 7 released already, semantic web support built-in – Release candidate version on its way
Semantic search
Opo (Online presence ontology)
• aims to unify presence information and status notification processes across different services:
– Twitter, Facebook, Foursquare, etc.
• Help solve the information overload issue at the same time, by providing a means to identify who / which community the information should reach: sharing spaces
MOAT (meaning of a tag)
• moat-project.org
• A model to define "meanings" of tags
– SPARQL → dbpedia.org/resource/SPARQL
• User-driven interlinking • Tagged content enters Linked Data web
• Collaborative approach towards the sharing of meanings in a community

OneSocialWeb
Openid connect
"an Interoperable identity interchange protocol for the social web [...] all the technology is on the verge of being ready"
Facebook open graph
• Allows metadata from external pages to be embedded (claimed) within facebook
• E.g. metadata about a restaurant (name, location, contacts) could be imported into a facebook news feed via a like button
• Good for facebook, good for the semantic web? Yes!
An object described using OGP
e.g. Linking ogp objects to blog posts / reviews
OGP in RDF (FOAF, DC, SIOC, GR)
Twitter Annotations
• forthcoming initiative by Twitter:
– attach arbitrary metadata to any tweet
– overall limit for the metadata payload
– May be able to attach RDF-type statements
• Going beyond annotating tweets with geotemporal information:
– new types of / properties for tweets
