The document discusses the use of the Semantically-Interlinked Online Communities (SIOC) ontology to enhance interoperability on the social web by linking social data through semantic web technologies. SIOC, adopted by numerous applications since its 2007 submission to W3C, has seen significant growth in data representation with millions of instances generated across various social platforms. The text also outlines potential applications of SIOC in areas like e-participation, citizen sensors, and social semantic journalism.

1. Lots of sioc data, now what?

2. Data silos on the social web

3. Can be linked
via semantics

4. Social Semantic Web

5. 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

6. 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

classes and properties

11. Some applications using sioc

12. 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

14. An ontology stack for the social
semantic web

15. Distributed
Architecture

16. 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 superceded by schema.org?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!

17. So…
HOW MUCH SIOC DATA IS OUT THERE?

18. Sindice 2011
• Trec 2011 dataset
• From 270k SLDs
– data.sindice.com/
trec2011/statistics.html
• Top 10 classes plus some
of the social semantic
web ones >>

19. Sindice 2012: classes
• Total instances of sioc classes: 7.7M
– Up 200k in three months
• Most occurences: sioc:Item (2.2m)
– Followed by:
• UserAccount (1.6m), Microblogpost (1.3m), Post
(800k), user (700k), comment (400k)...
– Note: 1 billion foaf:Person instances!!!
• Used on most [distinct] sites:
– Item (7k), useraccount (7k), post (3k)...

20. Sindice 2012: predicates
• Total instances of sioc predicates: 22.5M
– Up 400k in three months
• Most occurences: sioc:follows (4.6m)
– Followed by:
• topic (4m), account_of (3.5m), has_creator
(2.7m), links_to (1.5m), has_discussion (1.3m)...
• Used on most [distinct] sites:
– Has_creator (8k), num_replies (7k), name
(2k), account_of (1.5k), reply_of (1.5k)...

21. Sindice 2012: namespaces
• Sioc data is being generated from 10k
distinct domains (2k slds) (plus 2k
domains for the sioc types module)
– Increasing by about 100 domains a month
– No doubt helped by drupal!
• Foaf data is being generated from 3M
distinct domains (100k slds)
– Increasing by over 1000 domains a month

22. Commoncrawl
• Muehleisen and bizer
– Ldow 2012 @ www 2012
• 1.5 billion web pages
• 3 billion RDF quads
• Top 20 rdfa types >>

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

24. 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

25. Sioc-related initiatives

26. Brainstorm ontology

27. 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

28. 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
–

29. cross-wiki integration using sioc

30. Using ppo/ppm to access sioc
+foaf data

31. New! social semantic journalism
