2. AKT Workshop January 2001 2 CoAKTing IFD n Objective is to advance the state of the art in collaborative mediated spaces for distributed e- Science collaboration through the novel application of knowledge technologies

3. AKT Workshop January 2001 3 Collaboratory Concept A centre without walls in which the nations researchers can perform their research without regard to geographical location – interacting with colleagues, accessing instrumentation, sharing data and computational resource, and accessing information in digital libraries 1993 NSF study

4. AKT Workshop January 2001 4 Scenario n Meeting rooms linked over network n Potentially labs too – and smart spaces in general n Events in rooms provide annotation, e.g. u Use of documents u Moving through agenda u Slide transitions u People arriving and leaving u Note taking

5. AKT Workshop January 2001 5 AKTspects n Ontologies to enhance media-rich annotations of group problem solving n Planning and knowledge based task support to enhance issue-based process/activity discussions n Scholarly discourse and argumentation to enhance collaborative meeting structures n Presence and visualisation to enhance group peripheral awareness at a distance

6. AKT Workshop January 2001 6 History of proposal n Early discussions about CVW and experiments n Discussions with Nigel and Tom Rodden about Next Generation Access Grid, and the Advanced Collaborative Environments Working group of the Global Grid Forum n Existing work at partner sites u Continuous metadata u Knowledgeable devices (Equator bridge) u Compendium, BuddySpace u Intelligent Process Panels

10. AKT Workshop January 2001 10 Key Issues n The move from computers as specialist devices to everyday products n The move from identified user to general citizen n The involvement of new design approaches u e.g. art and design traditions n The development of new devices and new forms of interaction

16. AKT Workshop January 2001 16 Compendium n Compendium centres on face-to-face meetings n enabling groups to elicit, organise and validate information n improving communication between disparate communities tackling ill-structured problems n real time capture and integration of hybrid material (both predictable/ formal, and unexpected/informal) into a reusable group memory n transforming the resulting resource into the right representational formats for different stakeholders.

17. AKT Workshop January 2001 17 Process Panels n Open Planning Process Panels are based on explicit models of the planning process n Can coordinate the development and evaluation of multiple courses of action n Provides workflow coordination and visualisation

18. AKT Workshop January 2001 18 Jabber Jabber is an XML-based, open-source system and protocol for real-time messaging and presence notification.

22. AKT Workshop January 2001 22 e-Science and Grid Computing n e-Science is the large scale science carried out through distributed global collaborations enabled by the Internet. n e-Science is characterised by access to very large data collections and very large scale computing resources used by a large body of collaborating but geographically distant engineers or scientists. n The established architecture for the e-Science computing infrastructure is the Grid, and grid computing is now a subject of significant research and development in the US and Europe. n The UK Grid vision pays particular attention to the processes by which Grid applications contribute to the creation and delivery of information and knowledge.

24. AKT Workshop January 2001 24 Web services n Instantiation of service-oriented model u XML Protocol u Web Services Description Language u Universal Description Discovery and Integration n Workflow description u Web Services Flow Language u XLang n Other proposals emerging n Note relationship to agent-based computing n Open Grid Services Architecture

25. AKT Workshop January 2001 25 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 - TBL

26. AKT Workshop January 2001 26 n We have a vision of e-Science with a high degree of easy to use and seamless automation, with flexible collaborations and computations on a global scale. n To achieve this we need to bring together: u Grid computing u Service-oriented architectures u Semantic Web F RDF F Knowledge technologies Vision

28. AKT Workshop January 2001 28 Motivation for Semantic Grid activity n Gap between vision of e-Science and current endeavours n Three layer model compelling but much hand- waving about knowledge layer n Concern about scalability assumptions n Lack of holistic approach – Grid starting at socket on wall n Need for universal architecture
