Semantic Web f acilitates :

Innovation in Social Tools

Provides rich, structured data

from Social Media Sites:

Blogs, Bulletin boards, Wikis, ...

Data that can be used in:

Web 2.0 applications (Mash-Ups, ...)

Social Media integration and search

What is Semantic Web? Layer o n the Web – precise, structured information on : Objects on the web and in the real world Relations between them Resource Description Framework (RDF) Foundation of the Semantic Web Graph with objects (nodes) and relations between them Easy Integration of Data Data of different nature (FOAF, SKOS, RSS, …) SIOC – model of data – for social media sites

Layer o n the Web – precise, structured information on :

Objects on the web and in the real world

Relations between them

Resource Description Framework (RDF)

Foundation of the Semantic Web

Graph with objects (nodes) and relations between them

Easy Integration of Data

Data of different nature (FOAF, SKOS, RSS, …)

SIOC – model of data – for social media sites

Evolution of online community sites Online community sites: Provide a valuable source of information May contain rich meta-information But are isolated from one another: Many sites discussing complementary topics Next steps: Connect sites together Add more value: Let other sites know more about the structure and contents Make more use of tagging and semantic metadata

Online community sites:

Provide a valuable source of information

May contain rich meta-information

But are isolated from one another:

Many sites discussing complementary topics

Next steps:

Connect sites together

Add more value:

Let other sites know more about the structure and contents

Make more use of tagging and semantic metadata

Limitations of Bulletin Boards

What is SIOC? Semantically-Interlinked Online Communities (SIOC) Connecting forums, posts from many types of online communities (blogs, forums, mailing lists, etc.) Interesting possibilities: Distributed linked conversations Decentralised discussion channels and communities “ I […] think the concept is HOT” – Robert Douglass, Drupal Developer “ It just dawned on me that the burgeoning SIOC-o-sphere (online communities exporting and exposing content via SIOC Ontology) is actually: Blogosphere 2.0” – Kingsley Idehen, Founder and CEO of OpenLink Software

Semantically-Interlinked Online Communities (SIOC)

Connecting forums, posts from many types of online communities (blogs, forums, mailing lists, etc.)

Interesting possibilities:

Distributed linked conversations

Decentralised discussion channels and communities

“ I […] think the concept is HOT” – Robert Douglass, Drupal Developer

“ It just dawned on me that the burgeoning SIOC-o-sphere (online communities exporting and exposing content via SIOC Ontology) is actually: Blogosphere 2.0” – Kingsley Idehen, Founder and CEO of OpenLink Software

The Main Concepts in SIOC

How can SIOC data be used?

SIOC Tools and Data Demo of a WordPress SIOC plugin + Semantic Radar Firefox extension Now we’ve got the data.

Demo of a WordPress SIOC plugin

+ Semantic Radar Firefox extension

Now we’ve got the data.

SIOC Tools and Data Demo : WordPress SIOC plugin Creates data “pages” for all blog pages Now we’ve got the data.

Demo :

WordPress SIOC plugin

Creates data “pages” for all blog pages

Now we’ve got the data.

Using RDF – well, it’s very simple !!! Python: import RDF # Redland Python bindings m = RDF.Model() m.load('file:///data.rdf') for statement in m: print statement

Python:

import RDF # Redland Python bindings

m = RDF.Model()

m.load('file:///data.rdf')

for statement in m:

print statement

SIOC Tools and Data Demo : WordPress SIOC plugin Creates data “pages” for all blog pages Semantic Radar Firefox extension Detects data on web pages SIOC Browser (in Python) Data are linked – follow “rdfs:seeAlso” links to see more SIOC Explorer (in Ruby on Rails) Faceted browsing SIOC makes data available : Opens up Social Media sites Make Your Own Applications !!!

Semantic Radar Firefox extension

Detects data on web pages

SIOC Browser (in Python)

Data are linked – follow “rdfs:seeAlso” links to see more

SIOC Explorer (in Ruby on Rails)

Faceted browsing

SIOC makes data available :

Opens up Social Media sites

Make Your Own Applications !!!

The path to Semantic Web 2.0 The Semantic Web effort is mainly towards producing standards and recommendations that will interlink applications The Web 2.0 meme is about providing user applications Not mutually exclusive: http://www.oreillynet.com/xml/blog/2005/10/is_web_20_killing_the_semantic.html With a little effort, many Web 2.0 applications can and do use Semantic Web technologies to great benefit Take Web 2.0 and combine them with the Semantic Web
