    • Chapter 6 Building Semantic Web
    • The Web Agent Resource Resource Agent Resource Agent WEBAkerkar: Foundations of © Narosa Publishing House, 2009 2Semantic Web.
    • Evolution of Web Web Web Semantic Web Migrated Web Semantic Web Module 1 Module 2 Module 3 Module 4 Module 5 (1995) (1998) (1999) (2000) (2001) The WebAkerkar: Foundations of © Narosa Publishing House, 2009 3Semantic Web.
    • Vision of Semantic WebAkerkar: Foundations of © Narosa Publishing House, 2009 4Semantic Web.
    • Web Services• Web services is a software system identified by a URI, whose public interfaces and bindings are defined and described using XML.Akerkar: Foundations of © Narosa Publishing House, 2009 5Semantic Web.
    • Infrastructure Directory Service Security Applications Choreography Web Services Service Descriptions in WSDL SOAP URIs XML HTTP, SMTP, other transportAkerkar: Foundations of © Narosa Publishing House, 2009 6Semantic Web.
    • Web Service Scenario UDDI Points to Description Registry WSDL Describes Service Search Service Points to Service SOAP Service Consumer Web ServiceAkerkar: Foundations of © Narosa Publishing House, 2009 7Semantic Web.
    • Web Service Technologies • SOAP for accessing Web Services • WSDL for describing Web Services • UDDI for publishing and looking up Web ServicesAkerkar: Foundations of © Narosa Publishing House, 2009 8Semantic Web.
    • CombinationSemantic Web + Web Services = Semantic Web Services• Use Semantic Web technologies to describe Web ServicesAkerkar: Foundations of © Narosa Publishing House, 2009 9Semantic Web.
    • OWL-S Service presents ServiceProfile Resource offers Service described by ServiceModel supports ServiceGroundingAkerkar: Foundations of © Narosa Publishing House, 2009 10Semantic Web.
    • Semantic Web Services (SWS)• The SWS architecture – a set of components that support the usage activities. – Between a requester and a provider, components such as a register, a reasoner, a matchmaker, a decomposer and an invoker. – The components have different names and scopes across individual approaches.Akerkar: Foundations of © Narosa Publishing House, 2009 11Semantic Web.
    • SWS Infrastructure – Usage activities • define functional requirements; – the architecture • defines the components needed for accomplishing these activities; and – the service ontology • aggregates all concept models related to the description of SWS and • constitutes the knowledge-level model of the information describing and supporting the usage of the services.Akerkar: Foundations of © Narosa Publishing House, 2009 12Semantic Web.
    • Main Players – W3C – DARPA – EU – Funded Research & DevelopmentAkerkar: Foundations of © Narosa Publishing House, 2009 13Semantic Web.
    • Proof & Trust• Proof: – Digital signatures plays an important role in proof. – Security technologies like encryption and access control can be used to ensure confidentiality of information.• Trust: – Everyone should be able to define a trust model for himself, – A mechanism is necessary to derive the degree of trust for each new source. – WEB OF TRUST!Akerkar: Foundations of © Narosa Publishing House, 2009 14Semantic Web.
