1. CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7

2. When the web was in its early days, we didn’t know exactly what to show on a computer screen.

3. A company card?

4. A call to action?

5. A button ?

6. A shop?

7. We call this period web 1.0.

8. Web 1.0 was all about our search for online viability.

9. When we got a grip on the technical part, the real possibilities of the web became more clear.

10. We discovered the power of networks.

11. The power of links

12. The power of collaboration

13. The power of content and reach

14. The power of friends

15. This is what we call web 2.0.

16. Web 2.0 is all about the power of networks.

17. Basically, web 2.0 is a social change. The technical part of the web hasn’t changed very much.

18. But, web 3.0 will be driven by technological changes.

19. Web 3.0 - the semantic web - is about the meaning of data.

20. Suppose, I am a stamp collector...

21. Over the years I’ve collected a lot of stamps.

22. About every stamp, I made a document

23. That’s a lot of documents But…

24. How will I find that specific stamp? ?

25. Ah, of course !

26. This is the web we have today: a huge collection of documents

27. The words of all those documents are indexed. We can search for keywords.

28. Now, suppose I search for all red stamps…

29. What do I get ? Red stamps Stamps from Cambodia (Khmer Rouge) Stamps from the Red Sea Stamps from the 140 th anniversary of the Red Cross Stamps with red dragons

30. Not very intelligent, but how can a computer know what I mean?

31. Answer: when we structurally describe that a stamp is a stamp and red is a color.

32. Describing data in a structured way can best be done in a database.

33. Different databases can be connected.

34. A database with stamps A database with countries A database with colours A database with stamp traders

35. Web 3.0 creates a big collection of databases which can be connected on demand.

36. Agreements are made on the structure of data and the way data is described. Where the data is located is irrelevant. Linking data is the power of web 3.0.

37. So, “I want all the red stamps, designed in Europe, but used in the U.S.A., between 1980 and 1990” is a question that will get a better answer with web 3.0.

38. This definition of web 3.0 is a ‘narrow’ definition. Like web 2.0, web 3.0 stands for a range of developments.

39. A broader definition of web 3.0: A fast broadband connection to the internet, always and everywhere. Open source techniques and free data (Data as a Service) Open identities Software as a Service (e.g. Google docs)

40. First Web 3.0 application? You judge: http://www.youtube.com/watch?v=TJfrNo3Z- DU&feature=player_embedded

41. Activity Individually, open Safari and go to: Go to : freebase.com Optional: Use your Google account or create a new account at Freebase to see apps source codes. How does Freebase exemplifies Web 3.0? As outlined in the aforementioned slides. What features of Freebase did you find most relevant and why?
