  • Outline
    • Web 2.0
    • Limitation of Web 2.0
    • Introduction of Web 3.0 ( Semantic Web)
    • How Semantic web changes the world
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Web 2.0
    • Web 2.0 is simply what we feel now
      • FaceBook, My Space, Twitter, Google , ….
    • Feel the difference between Web 2.0 and Web 1.0
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Web 1.0
    • Let’s See How Web 1.0 would have invoked our Sleep with
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Web 1.0
      • Disable All your Javascript
        • Ohh no!!!
          • Show / Hide Div won’t work
          • Ajax Won’t work ( no auto update  )
          • Perhaps remember me in this pc won’t work
          • Your chat won’t work (  )
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Web 1.0
      • Disable All Adobe Flash Component
        • Ohh no!!!
          • Your Video link won’t work (it is just an image now  )
          • No farmville (  )
          • And many thing ( I don’t know )
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Web 1.0
      • And Even More disaster would HAPPEN With web 1.0
      • So,Now we Know how 2.0 Excites Web Surfing
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Limitation of Web 2.0
      • Yes, Still there is limitation
      • WWW is yet a fool
      • Web pages are designed to be read by people not by Machine
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Limitation of Web 2.0
      • How to feel ?
      • Ok, Now its time to know Semantic Web (web 3.0)
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0)
    • Semantics ?
      • Syntax means how we say something
      • Semantics in meaning behind what we say
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0)
    • Example:
      • I love Technology
      • I Technology
        • Here syntax is letters words, punctuation
        • Semantics what the line actually mean.
        • In this case it mean that I enjoy reading new technology
      • But they have different syntax yet same semantics
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0) continued …
    • Our 2.0 technology runs on syntax and not on semantics.
    • Our HTML (HTTP/1.1) is all about syntax but does our machine bother what web pages are really about ?
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0) continued …
    • So, Now we need to know how things are in semantic web.
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0) continued …
    • In semantic web everything will have an URI
      • Everything means everything ( every person, every country, … infact probably every noun )
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0) continued …
    • Ex:
      • Jane love Joe
        • Jane(uri1) Love(uri2) Joe(uri3)
      • Jane love chokolet
        • Jane(uri1) Love(uri2) chokolet (uri4)
        • But this really are represented by tuples.
        • And Semantic Web are made of many tuples.
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Semantic Web ( Introduction of web 3.0) continued …
    • So at last we will have an graph of tuples like below . ( GGG and ! WWW)

  • What is RDF
    • Resource Description Framework
    • Subject Predicate Object
    • Dave Like Cookies
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Representing RDF Statement
    • Everything is Subject Predicate Object
    • Representing “Dave Likes Cookies”
    • N3 Notation:
      • @prefix pref:< http://example.org/vocabulary# >.
      • <#dave><pref:likes><#cookies>.

  • Putting Semantic Info to Web Pages
    • If your webpage know the semantics of Information , then after browsing a medical diagnosis site your browser/machine has the knowledge of a pathologist.
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Putting Semantic Info to Web Pages
    • In the following example we will try to learn our browser/machine that
    • Jane is a person (probably software Eng  )
    • Jane’s full name is Jane McJanerson
      • Mac is a person
      • Mac’s full name is Mac ….
      • Jane knows Mac
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Learning that Jane’s Name is Jane McJanerSon Semantic Web Open Source Software with South-East University, Dhaka.
  • Learning that Jane’s Name is Jane McJanerSon and he is a person Semantic Web Open Source Software with South-East University, Dhaka.
  • Learning both Jane & Mac Semantic Web Open Source Software with South-East University, Dhaka.
  • Learning Jane knows Mac Semantic Web Open Source Software with South-East University, Dhaka.
  • What about the browser / Machine Now
    • Now the machine knows many thing.
    • You can query the machine about Mac , jane
    • So, the machine is no longer fool now 
    Semantic Web Open Source Software with South-East University, Dhaka.
  • How Semantic web will help us?
    • In finding news, people, movies and everything in more effectively

  • Statistics of Internet Growth
      • People connected : > 1.7 billion
    Semantic Web Open Source Software with South-East University, Dhaka.
  • Statistics of Internet Growth
      • Data On Internet :
        • 2006: 161 EB ( Exabyte)
          • 1 EB = 1million Terabytes
        • 2010: 988 EB
        • Data on Internet Grows Double Every Two years .
        • Ref:http://www.youtube.com/watch?v=zXlKIJoSLVM

  • Do we really have alternative?
      • Tagging
      • Tagging vs Semantic Web
    Semantic Web Open Source Software with South-East University, Dhaka.
  • How semantic web changes the world
      • Every websites are closely connected with each other.
        • Results consistency among information (every where on internet)
        • Every people are connected closely with each other
          • (More than like they are connected today with Facebook)
        • Better Web Searching
        • Machines can Share Share knows by themselves voluntarily
