The document discusses the semantic web, which is an evolution of the current web where computers will be able to analyze and understand all data on the web. It is being led by organizations like the W3C and aims to transform the current web of documents into a web of linked data through technologies like RDF. While companies like Google and Facebook are currently leading the development of the semantic web through their use of large user data, issues around privacy still need to be addressed as the semantic web continues to evolve.
![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 ”

- 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 http://content5.videojug.com/4c/4c3119ae-9ae4-9ca6-6135-ff0008cad0e6/how-to-build-a-brick-wall-2.WidePlayer.jpg
- 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 . • More info http://en.wikipedia.org/wiki/Resource_Descrip tion_Framework
- 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
