  • The Semantic Web
  • Semantic Web
    • Web 3.0
    • Web 1.0 - 2.0 a place for documents
    • Combine documents with meaningful data
  • Semantic Web
    • Uh oh, more technical stuff
  • Semantic Web
    • XML and RDF
    • XML - arbitrary structure of tags, hidden labels, annotations
    • RDF - creates meaning that allows computing systems, or Agents , to interpret and make sense of the data
  • Semantic Web
    • RDF encodes in sets of triples
      • Subject
      • Verb
      • Object
  • Semantic Web
    • Take a step back
      • What’s your zip code?
      • If I tell you my zip code, shouldn’t you know my city?
  • Semantic Web
    • Ontologies
      • Representation of a set of concepts within a domain and the relationships between those concepts
  • Semantic Web
    • Consider a device which is a sort of mechanized private file and library
    • The device is mechanized so that it is has exceeding speed and flexibility
    • Enlarged intimate supplement to memory
  • Semantic Web

    • Vannevar Bush
    • As We May Think
    • Atlantic Monthly
  • Semantic Web
    • Any item may be caused at will to select immediately and automatically another
    • The process of tying two items together is the important thing
  • Semantic Web
    • All forms of intelligence whether of sound or sight, have been reduced to the form of varying currents in an electric circuit in order that they may be transmitted
  • Semantic Web

    • Scientific American
    • The Semantic Web
    • Tim Berners-Lee, James Hendler and Ora Lassila
  • Semantic Web
    • A place where software Agents read and interpret data providing services
    • Artificial Intelligence
  • Semantic Web
    • Imagine Mom and her two adult children Lucy and Pete
    • At the doctor's office, Lucy instructed her Semantic Web Agent through her handheld Web browser
  • Semantic Web
    • The Agent promptly retrieved information about Mom's prescribed treatment from the doctor's Agent
  • Semantic Web
    • The Agent checks for providers within a 20-mile radius of her home
    • Provided with ratings of excellent or very good
  • Semantic Web
    • Matches available appointment times with Pete's and Lucy's busy schedules
  • Semantic Web
    • In a few minutes the Agent presents them with a plan
    • Pete doesn’t like it. The University Hospital is all the way across town from Mom's place
  • Semantic Web
    • Pete sets his Agent to redo the search with stricter preferences about location and time
  • Semantic Web
    • Almost instantly the new plan is presented: a closer clinic with earlier times
  • Semantic Web
    • Pete will have to reschedule a couple of less important appointments
  • Semantic Web
    • Semantic Web today
      • The Semantic Web Revisited IEEE INTELLIGENT SYSTEMS MAY/JUNE 2006
      • More standards developed

    • What does all this mean?
  • Semantic Web
    • The Semantic Web isn’t ready for prime time
    • Librarians, especially catalogers, will have a role in this future
    • The train is in the station
  • APIs, Mashups, and Semantic Web
    • What should librarians be doing?
      • APIs – push vendors for APIs into their systems
      • Mashups – invest money, staff, and resources into creating useful applications
      • Semantic Web – continue to monitor and jump in when the time comes
