Transcript of "Semantic Web Services Framework for Computational Interoperability"

  1. 1. Dr. Thiti VacharasintopchaiSIMDISASTER 2008Asian Institute of TechnologyJanuary 30, 2008 1
  2. 2. BackgroundWeb Services & Semantic WebSemantic Web Services Framework forComputational MechanicsExampleConclusions 2
  3. 3. Background 3
  4. 4. CAE analyses need close guidance by people Computers performing structural analysis using numerical methods Software Reuse Sharing & Finding of modules / subroutines Modeling Design codes 4
  5. 5. CAE analyses need close guidance by people Computers performing structural analysis using numerical methods Data consistency Interoperation among different software packages / modules SI units – Meter, Newton, Pascal English units – Foot, Pound, psi Example: Loss of NASA Mars Vehicle 5
  6. 6. To facilitate the interoperation and sharing of computing tools and computing resources which improve the collaboration between research engineers such that computers operate more effectively and accurately with least human intervention 7
  7. 7. 8
  8. 8. An Internet paradigm of distributed computingWhy is it interesting? Build computer software by RPCs to shared subroutines Ex. Subroutines: Equation solver vs. Whole FEM analysis Uses the Internet as communication medium Relies on W3C standards HTTP & XML (SOAP) Platform-neutral Java, .NET, C , Fortran, etc. Windows, Mac, Linux, etc. 9
  9. 9. Web Services therefore could be an enablingframework to allow software developed by different group of people and deployed on various computing platform (workstation, clusters, supercomputers)to interoperate 10
  10. 10. 11
  11. 11. The Semantic Web is a vision for the next generation ofthe Web on which information will be useful andmeaningful not only for people but also for computersComputers will be able to understand pieces ofinformation on Web pages rather than merelypresenting them to users, and would be able toautonomously assist users in manipulating suchinformationXML SOAP messages between computers will also bebetter understood 12
  12. 12. Semantic Web could be anenabling framework to allow Web Servicesdeployed on the Internet to communicate more effectively and reduce the chance of mishandlings of instructions and data 13
  13. 13. Documents (information) on the present Web canbe transformed into the semantic one byaugmenting them with metadata aimed atcomputersMetadata—data about other data—enablecomputers to determine the meaning ofinformation communicated by following hyperlinksto definitions of key terms and rules for reasoningabout them logically 14
  14. 14. Augmenting“analysis command” with metadata Sample XML “Request” Let’s have a look at these 17
  15. 15. Sample DefinitionWhat is ASTM A36? 18
  16. 16. Sample Definition Support Condition:Cantilever All nodes on Plane X = 0 are pinned What is a Pinned node like? 19

Web Services can an enabling framework toallow software developed by different group of people and deployed on various computing platform to interoperateSemantic Web can be an enabling framework toallow these Web Services to communicate more effectively and reduce the chance of instructions and data mishandling 31
  28. 28. A framework for the application of Web Servicesand the Semantic Web in engineering software hasbeen proposed and an illustrative case study hasbeen presentedThis framework will be particularly useful toimprove the collaboration among researches inHigh-performance Computing and NumericalSimulations 32
