10. Where did The Semantic Web begin?
With hyperlinks

11. From the creator of the web
“I have a dream for the Web [in which
computers] become capable of analyzing all the
data on the Web ”
Tim Berners-Lee

12. The Current State of the web
Something as simple as trying to view a video

13. Examples
Google Now
Facebook

15. Google and Facebook leaders of
The Semantic Web
• They’ve the resources to spend
• They already have the users
• Hence they already have the data
• Their motivation – Money?

16. Are there any issues?
• Well… yes.
• Privacy
Google Adverts
Facebook Adverts

17. In my opinion..
• The Semantic Web is here,
Its here
• But wont ever truly be finished. It will always be
evolving
but it’ll never be
finished

18. It’s built using: Resource
Description Framework (RDF)
@prefix : <http://www.example.org/> .
:john a :Person .
:john :hasMother :susan .
:john :hasFather :richard .
:richard :hasBrother :luke .

19. Its something to think about for
your project
• Include RDF for your data
• Your relational database is a simple example
▫ UserA follows UserB
▫ UserA is from Ireland
▫ UserD loves a film: The Notebook
