28
Background of Semantic Web
Internet Technologies

• Communication Problem among System in short of
  Information Infrastructure
• Limitation of HTML
• Limitation of XML and its Complement
• Systematic Definition of Semantics of Resource in
  Current Web, a kind of Extension to Result the
  Working of Automating Machine

• RDF Schema

30
Core Concept of Semantic Web
Internet Technologies

• Can use URI (Uniform Resource Identifier) as
  Identifier
• Can access through network Electronic Document,
  Image, Information Service, Collection of
  Resource
• Can not access through network Human, Company,
  Books
• Abstract Concept Constructor, Subject,
  Title

31
RDF (Resource Description Framework)
Internet Technologies

• Describe Web Resource
• Framework to describe corresponding information
  to exchange information among application
  programs without loss of semantics

• Triple (Subject, Predicate, Object)

32
A Simple RDF Statement
Internet Technologies
http//www.example.org/index.html has a
creation-date whose value is August 16, 1999
Triple Description
exindex.html, extermscreation-date, "August
16, 1999
33

  information
• Provide Menu list for dinner and Recommend Wine,
  but Exclude Sauterne.
• Query to request Logical Reasoning
• Can be done when trace the relations between
  classes or attributes.
• Super,Sub, Equal, Reverse, Conjuction, etc

35

  in given schedule by some conference
  automatically.
• Query 5
• Find the service to provide Narita-San Francisco
  the cheapest Air-Ticket with Specific credit
  card, and Reserve it.

• Find the services that integrate the various
  exhibition, meeting plans into private
  information system.

37
