  1. Semantic Web Services CS - 6V81 University of Texas at Dallas November 23, 2009 Presented by- Rohit Sharma

  2. Agenda!!! • Picture? • Why? • What? • Types? • Tasks? • Structure? • Conclusion http://www.authenticresourcing.com/2008/staff-problems.gif

  3. Picture ? http://www.w3.org/2004/Talks/0612-sb-wsswapps/farside2-2.gif

  4. Picture ?

  5. Why? Syntactic Interoperability [Before] Semantic Meaning of Messages [After] Great access of Content [Before] Great access of Services [After] OK, 2 points aint sufficient son. *Cough* [ LOL ]  Wait NOOB.

  6. Why? Users & Software Agents Discover [Web Resources] Locate [Web Resources] Invoke [Web Resources] Compose [Web Resources] Monitor [Web Resources] Particular Services Particular Properties Do all of the above with high degree of automation I am LOST , so what is Semantic Web Services?

  7. What? • Component of Semantic Web [It is] • Conventional Web Service [Just Like] • Server End of Client-Server System [which is] • Machine-to-Machine Interaction [for] • Via World Wide Web [using] • Any Technical Term or Ontology for this? • OWL-S: Semantic Markup for Web Services • Can I go home I am getting Migraine ………

  8. Types? • Atomic *Simple* • Single Computer Program, Sensor, or Device • Invoked by a Request Message • Performs its Task • Produces a Single Response • No Ongoing Interaction • Composite *Complex* • Composed of Multiple More Primitive Services • Extended Interaction

  9. Tasks? • Automatic Web Service Discovery • Automated Process for Location of Web Services • Provide a Particular Class of Service Capabilities • While Adhering to some Client-Specified Constraints What The Hell? • Automatic Web Service Invocation • Automatic Invocation of Web Service by Program/Agent • Given Only a Declarative Description of that Service Explain or Sue !!! • Automatic Web Service Composition & Interoperation • Involves Automatic Selection, Composition & Interoperation • To Perform some Complex Task • Given a High-Level Description GRRRRR *Nerd Rage*

  10. Structure? Motivated by the Need to Provide 3 Types of Knowledge *each characterized by the question it answers* • What Does the Service Provide for Prospective Clients? --- Service Profile • It is used to Advertise the Service • The Service Profile tells “What the Service Does“ • Helps a Service-Seeking Agent • To Determine Whether the Service Meets its Needs

  11. Structure? Motivated by the Need to Provide 3 Types of Knowledge *each characterized by the question it answers* 2. How is it used? --- Service Model • Uses the property “describedBy” • Tells a Client How to Use the Service, by Detailing the Semantic Content of Requests • The Conditions Under which Particular Outcomes will Occur • The Step by Step Processes Leading to Those Outcomes

  12. Structure? Motivated by the Need to Provide 3 Types of Knowledge *each characterized by the question it answers* 3. How does one interact with it? --- Service Grounding • Provides the Needed Details about Transport protocols • Specifies Input , Output & Way of Exchanging Data

  13. Visualization !! http://www.w3.org/Submission/OWL-S/Service-Ontology1.1.gif

  14. Conclusion: • OWL-S is an Ontology for describing Web Services • Enable Users and Software Agents to do a LOT (their way) • Better place where people can not only find information but also get things done http://www.cartoon/teen/church/light.gif
