24. Semantics

25. Social Semantic Web

26. 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

27. Foaf (friend of a friend)

28. 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

34. 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

36. Some of the SIOC core ontology
classes and properties

39. From last October

40. 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

41. Semantic search

42. 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

43. 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

48. Diaspora effort
nyti.ms/aDYjKQ and joindiaspora.com

49. Appleseed project

50. OneSocialWeb

51. Openid connect
"an Interoperable identity interchange
protocol for the social web [...] all the
technology is on the verge of being
ready"

52. 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!

53. An object described using OGP

54. e.g. Linking ogp objects to blog
posts / reviews

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

56. 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
