  3. Vision: e-Science e-Science is about global collaboration in key areas of science and the next generation of [computing] infrastructure that will enable it. e-Science will change the dynamic of the way science is undertaken John Taylor, Director General of UK Research Councils IAAI Panel

  4. Vision: e-Science ‘[The Grid] intends to make access to computing power, scientific data repositories and experimental facilities as easy as the Web makes access to information.’ Tony Blair, 2002 IAAI Panel

  16. Vision: e-Research • Researchers working in all disciplines are faced daily with a wide variety of tasks necessary to sustain and progress their research activity • These involve the analytical aspects of their work, access to resources, collaboration with fellow researchers, and project management and admin • These tasks rapidly increase in scale and complexity as collaborations grow larger, become more geographically distributed and involve a wider range of disciplines JISC • Not just new Science • e-Social Science • e-Humanities • e-Arts • e-Research • e-Business • e-Anything • … • And new disciplines! IAAI Panel

  17. Vision: HASTAC Humanities, Arts, Science and Technology Advanced Collaboratory HASTAC is an international, interdisciplinary consortium which seeks to create, develop, advance and utilize a broad range of leading computing and information systems while contributing to an understanding of the interconnections between the human sciences, natural sciences, arts, and technology in a complex global society IAAI Panel

  18. Vision: Joining up • These visions are all about joining resources and people together in new ways in order to create new things • Researchers can focus on the real research • The research process is accelerated • New research results are possible • New research areas are possible • NB s/research/business/ IAAI Panel

  19. Vision: The Grid Courtesy of Ian Foster IAAI Panel

  20. Vision: The Grid Grid computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation...we [define] the "Grid problem”…as flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources - what we refer to as virtual organizations From "The Anatomy of the Grid: Enabling Scalable Virtual Organizations" by Foster, Kesselman and Tuecke IAAI Panel

  23. On demand transparently constructed multi-organisational federations of distributed services Distributed computing middleware Computational Integration Two infrastructure enablers Grid Computing Semantic Web • An automatically processable, machine understandable web • Distributed knowledge and information management • Information integration IAAI Panel

  24. IAAI Panel

  25. Five Myths busted! • Isn’t it just for Physics? • No – Grids for Life Science and Medicine will dominate Grid applications • Think of the range and scale of data and the community! • Isn’t it just High Performance computing? • No – it’s a generic mechanism for forming, managing and disbanding dynamic federations of services • Data integration, data access, data transport will dominate • Application integration is the key IAAI Panel

  26. Five Myths busted! • Isn’t it just a bag of protocols glued together? • No – the Open Grid Service Architecture gives a well specified middleware stack built on industry standard web services • Isn’t it just Globus toolkit? • No – that is one reference implementation. • Isn’t it just a bunch of academic physicists? • No –all the commercial vendors are making serious investment. IBM DB2 and Oracle 10g will be grid-compliant IAAI Panel

  27. Specific services: drug discovery pipeline, sky surveys Grid Applications Standard services: agreement, data access and integration, workflow, security, policy, brokering… Open Grid Service Architecture Standard interfaces and behaviours for distributed systems: naming, service state, lifetime management, notification Web Service Resource Framework Web Service-Notification Standard mechanisms for describing and invoking services: WSDL, SOAP, WS-Security etc Web Services Grid Services IAAI Panel

  29. Origins of the Semantic Web The Semantic Web is an extension of the current Web in which information is given a well-defined meaning, better enabling computers and people to work in cooperation. It is the idea of having data on the Web defined and linked in a way that it can be used for more effective discovery, automation, integration and reuse across various applications. The Web can reach its full potential if it becomes a place where data can be processed by automated tools as well as people. W3C Activity Statement IAAI Panel

  30. Layers of Languages Attribution Explanation We are here! Rules & Inference Ontologies Metadata annotations Standard Syntax Identity IAAI Panel

  31. Resource Description Framework • Common model for metadata • A graph of triples • Query over and link together • RDQL, repositories, integration tools, presentation tools • The Network Effect Graphic courtesy of Tim Berners-Lee IAAI Panel

  32. OWL Web Ontology Language DARPA Agent Markup Language Ontology Inference Layer DAML OIL RDF EU/NSF Joint Ad hoc Committee The most popular ontology language in the world ever! DAML+OIL All influenced by RDF OWL Lite (thesaurus) OWL DL (reason-able) OWL Full (anything goes) A W3C Recommendation OWL IAAI Panel

  33. 5 More Myths Busted! • Isn’t it just AI and distributed agents (again)? • No – It is primarily metadata integration and querying • Don’t you need all that reasoning stuff? • No – A little bit of semantics goes a long way! (Hendler) • It only applies to the Web? • No – the technologies are being used for Enterprise integration, exposing data in a common model, common ontology languages, representing terminologies. • One big ontology of everything never works! • No – multiple ontologies; multiple everything! • One big Semantic Web! • No – lots of Semantic Web-lets, and expect it to break!

  35. The Semantic Grid Report 2001 • At this time, there are a number of grid applications being developed and there is a whole raft of computer technologies that provide fragments of the necessary functionality. • However there is currently a major gap between these endeavours and the vision of e-Science in which there is a high degree of easy-to-use and seamless automation and in which there are flexible collaborations and computations on a global scale. www.semanticgrid.org IAAI Panel

  50. Self-Organizing Semantic Grid …Our self-organizing Semantic Grid is now a constantly evolving organism, with ongoing, autonomous processing rather than on-demand processing. This evolving, organic Grid can generate new processes and new knowledge. David De Roure, Trends and Controversies IEEE Intelligent Systems, August 2003 IAAI Panel
