Web 1.0

• The web as an information portal
• Information exclusivity, be the first to own the
  content
• Dividing the www into usable directories
• Everyone has their personal own little corner in
  the cyberspace
• Lacks
• Context
• Interaction
• scalability

5
Web 2.0

• The web as a platform
• Focus on the power of the community to create and
  validate
• The power of a seemingly freer form of
  organization (tags)
• Setting up hooks for future integration (RSS,
  API)
• Lacks
• Personalization
• True portability
• Interoperability

The evolution to Web2.0

What is Web3.0?

• How will our information be organized?
• Will we still do the surfing or will the
  machine surf for us?
• Will the web look the same for me as it does for
  everyone else?
• What technology will become commonplace? Obsolete?

Suppose, I am a stamp collector...
9
Over the years Ive collected a lot of stamps.
10
About every stamp, I made a document
11
Thats a lot of documents
12
But
I want all the red stamps, designed in Europe,
but used in the U.S.A., between 1980 and 1990
13
How will I find that specific stamp?
?
14
Ah, of course !
15
This is the web we have today a huge collection
of documents
16
Not very intelligent, but how can a computer know
what I mean?
17
Answer when we structurally describe that a
stamp is a stamp and red is a color.
18
Describing data in a structured way can best be
done in a database.
19
Different databases can be connected.
20
A database with stampsA database with
countriesA database with coloursA database with
stamp traders
21
Web 3.0 creates a big collection of databases
which can be connected on demand.
22
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.
23
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.

(Note)
25
This definition of web 3.0 is a narrow
definition. Like web 2.0, web 3.0 stands for a
range of developments.
26
A broader definition of web 3.0

• A short definition from WikipediaThe Semantic
  Web is an evolution of the World Wide Web in
  which information is machine processable (rather
  than being only human oriented), thus permitting
  browsers or other software agents to find, share
  and combine information more easily.
• 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)

27
The semantic Web
28

• The semantic web is a web of data. HTML
  describes documents, while RDF describes things.
  Why talk about a page in terms of style and
  links, when you know a book has chapters and a CD
  has tracks?

Who is on the forefront

• Google lots of tools under its belt including
  universal search, user search history, google
  base, and google gadgets
• Twine Semantic Web, natural language and machine
  learning to make information and relationships
  smarter
• Swicki community built search portals
• Powerset the nuances of natural language

Twine

• To get a first taste of a semantic Web, lets
  take a look of Twine, the most hyped Web 3.0
  application developed by Radar Networks a year
  ago.  Twine is a Web application that helps you
  organize, share, and discover information around
  your interests with your friends, family, or the
  public.
• According to the Twines Web site, Twine is smart
  and it automatically organizes information,
  learns about interests and makes recommendations.
  Twine enables you to organize information you
  find or create on the Web including bookmarks,
  text, images, and videos. As you add information
  to Twine, it is automatically tagged so that you
  and others can find it more easily.  Twine looks
  at content and parses it automatically for the
  names of people, places, organizations and other
  subject tags. You are then able to navigate
  between related content, view recommended content
  and connect with recommended people around your
  interests.

37
How to use Twine

• Join Twines
• Fill in your profile with meaningful information
• Make connections
• Contribute
• Ask for help if you need it
• Be yourself
• Visit your connections
• Use RSS
• Take it one piece at a time
• And lastly have fun!

38
How is Twine different from Facebook or other
social media?

• Facebook is for tracking what's happening with
  your friends. Twine is for tracking what's
  happening with topics, hobbies or people that
  interest you. 
• With Twine, you can create a twine of any topic
  you'd like to track. It can be broad or niche. It
  can be popular or bizarre. Others who are also
  really into this topic will join the twine. You
  can share and exchange information with
  like-minded people who's into what you're into.

• Taking a look back, Web 2.0 brought us big
  buttoned clean websites, social networking, and
  most importantly user generated content. The web
  got personal. No longer were people just looking
  at websites, they are actively participating in
  building content and communities through
  uploading videos and photos, editing wikis and
  writing blogs.
