The document discusses the social semantic web and how semantics can help connect isolated social media sites and data silos. It provides examples of ontologies like FOAF, SIOC, and OPO that describe social relationships and interactions. Emerging initiatives like Facebook's Open Graph and Twitter annotations aim to embed semantic metadata in social media to link profiles, content, and conversations across platforms.

12. It's the social objects we
create…
• Discussions
• Bookmarks
• Annotations
• Microblogs
• Multimedia

13. …that connect us
to other people

14. Social media sites are like data
silos

21. Semantics

22. Social Semantic Web

23. 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

24. Foaf (friend of a friend)

25. 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

31. 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
60 applications or modules deployed on
hundreds of sites
• Web 2.0, enterprise information
integration, HCLS, e-government

33. Some of the SIOC core ontology
classes and properties

37. 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

40. Semantic search

41. 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

42. 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

47. 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!

48. OGP in RDF (FOAF, DC, SIOC, GR)

49. 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 geotemporal annotations:
– "type":{"attribute":"value"}
– "movie":{"title":"avatar"}
