1. Why the Semantic Web?
© W3C German-Austrian Office & PAUX Technologies, APE 2012
Bridge the gap between what humans see and what a browser “sees”
3

Give Uniqueness to concepts – example “bank”
http://dbpedia.org/page/Bank ✔

Provide access to lot’s of interlinked data – in a standardized manner
5
© W3C German-Austrian Office & PAUX Technologies, APE 2012
Allow for new ways to access the Web
• People who were born in Berlin before 1900
• Part of one answer from dbpedia (= Semantic Web version of Wikipedia):
“Alexander Gottlieb Baumgarten”born “1714-07-17”died “1762-05-26”

2. Semantic Web in a Nutshell
7
© W3C German-Austrian Office & PAUX Technologies, APE 2012
Identify things (“resources”) using URIs (Unique Resource Identifiers)
“Eric Miller” =
http://www.w3.org/People/EM/contact#me
8
© W3C German-Austrian Office & PAUX Technologies, APE 2012
Make statements about resources
• For humans: “Eric Miller has the email address [email protected]”
• For machines: triples consisting of Subject, Predicate, Object• http://www.w3.org/People/EM/contact#me
• http://www.w3.org/2000/10/swap/pim/contact#mailbox
• mailto:[email protected]
9

Consisting of source (subject), target (object),type of link (predicate)
Statements are like linksin the human Web

Main technologiesin the Semantic Web
• RDF: Describe Resources• “Eric Miller has the email address …”
• RDF Schema: Describe kinds of resources• “Eric Miller is a person”
• OWL: Richer descriptions (“ontologies”)
• SPARLQ: Query RDF• “Find me all persons who have an email address”
• “Find people who were born in Berlin before 1900”

3. Trends in Semantic Web
12
© W3C German-Austrian Office & PAUX Technologies, APE 2012
TREND: Linked Open Data
• Provide masses of data following the “5 stars of open linked data”
• More and more communities• Health Care & Life Sciences
• dbpedia in many languages
• Libraries
• eGovernment
• News provider
• …
13

TREND: Integrating Semantic Web into Web pages: RDFa

14
© W3C German-Austrian Office & PAUX Technologies, APE 2012
TREND: Build bridges to other approaches for metadata on the Web
• Example: schema.org
• Metadata vocabulary
• Used by Bing, Google, Yahoo! for presenting Web search results
• Can solve the ambiguity problem (“what is a bank?”)
