Current State Of the Semantic Web

3. Current State Of the Web
160 million websites
600 billion documents
56% English
70% in the Deep Web
Blogs and Wikis

4. Tim Berners-Lee Inventor of the World Wide Web
Director of the 3W Consortium
Named Greatest Living Genius
Inventor of the Semantic Web

5. Tim Berners-Lee Semantic Web Definition
A project designed to create a universal medium for all activity on the World Wide Web
The current web is a document web
The web of the future will be a data web

6. Semantic Web Examples
Personal
Medical
Research
Financial
Managerial

7. Problems
The Accural System

8. Problems – Language Language
To be successful, the semantic web must enable globalization.
More and more, countries are fighting the idea of English being the language of the web
Moving to a data web may mean that SQL becomes the language of the web

9. Problems – Security
Data security issues will be minimized if users accept the concept that all elements of the data web must be encrypted.
Privacy
HIPAA Continuum of Care

10. The Semantic Web

11. The Necessities
XML
RDF
OWL

12. The Necessities – XML XML Ξ eXtensible Markup Language
Rules for defining elements of documents for storage or for use on the Internet
There are thousands of rule sets in XML, including XBRL
Two types:
Well-formed – conforms with all XML rules
Valid – conforms to XML and additional rule sets (that are typically semantic), thus requiring XML Schema

13. The Necessities – RDF RDF Ξ Resource Description Framework
Standardized metadata modeling set
Uses triples, in subject-predicate-object form.
For example, This presentation has the color orange.
Presentation is the subject.
Has the color is the predicate.
Orange is the object.
Useful for both knowledge management and the semantic web.

14. The Necessities – OWL OWL Ξ Web Ontology Language
The family of accepted knowledge representation languages for authoring ontologies
An ontology is a model of some set of real-world concepts.
In short, ontologies classify nouns, describe their attributes, and outline their interrelationships.

15. The Necessities – OWL
Three versions of OWL are accepted by the W3 Consortium:
Owl Lite
OWL DL (which includes all of OWL Lite)
OWL Full (which includes all of OWL DL)
As ontologies build up, their interrelationships are controlled by mediators

16. Business Applications (via B2B) Web Service Modeling Ontology
(Requester)
Describes Needs
Searches for Services
Selects Service
Interoperates
(Provider)
Describes Services
Advertises Services
Interoperates

17. Elements of Interoperation
Capability
Formal description of the functionality of the service (desired and provided)
Choreography
Interaction style
Specifies inputs and outputs
Orchestration
How the service uses other services

18. The Required Levels of Interoperability
Communication Interoperability
All necessary data are precisely defined
Syntactic Interoperability
Multiple software components can interact regardless of languages, operating systems, and any/all other technological concerns
Semantic Interoperability
Most important and most difficult to achieve
Knowledge-driven ability to overcome differences in perceptions, assumptions, perspectives, and meanings

19. The Semantic Web – When?

20. The Semantic Web – When?
Using rules, queries, and logic to establish the achievement of all three levels of interoperability results in proof.
Proof, combined with encryption (and digital signatures) results in trust.
Then, the fun begins…

21. The Result: E-Commerce Redefined
Change will come very quickly
Legacy B2B Relationships
Long-term
Highly Defined
Tightly Coupled
Modern B2B Relationships
Undefined (usually short-) term
Casual
Complex

22. Current State Of the Semantic Web
Seven to nine million documents
Most common RDF
Dublin Core (1,500,000 Occurrences)
Most Common OWL
FOAF (650,000 Occurrences)
Resources
