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

• 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

over 400 sites
• Web 2.0, enterprise information
integration, HCLS, e-government

36. Some of the SIOC core ontology
classes and properties
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
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

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!
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
