CoAKTing IFD

• 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
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
Scenario

• Meeting rooms linked over network
• Potentially labs too and smart spaces in
  general
• Events in rooms provide annotation, e.g.
• Use of documents
• Moving through agenda
• Slide transitions
• People arriving and leaving
• Note taking

5
AKTspects

• Ontologies to enhance media-rich annotations of
  group problem solving
• Planning and knowledge based task support to
  enhance issue-based process/activity discussions
• Scholarly discourse and argumentation to enhance
  collaborative meeting structures
• Presence and visualisation to enhance group
  peripheral awareness at a distance

6
History of proposal

• Early discussions about CVW and experiments
• Discussions with Nigel and Tom Rodden about Next
  Generation Access Grid, and the Advanced
  Collaborative Environments Working group of the
  Global Grid Forum
• Existing work at partner sites
• Continuous metadata
• Knowledgeable devices (Equator bridge)
• Compendium, BuddySpace
• Intelligent Process Panels

Key Issues

• The move from computers as specialist devices to
  everyday products
• The move from identified user to general citizen
• The involvement of new design approaches
• e.g. art and design traditions
• The development of new devices and new forms of
  interaction

Compendium

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

17
Process Panels

• Open Planning Process Panels are based on
  explicit models of the planning process
• Can coordinate the development and evaluation of
  multiple courses of action
• Provides workflow coordination and visualisation

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

e-Science and Grid Computing

• e-Science is the large scale science carried out
  through distributed global collaborations enabled
  by the Internet.
• 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.
• 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.
• The UK Grid vision pays particular attention to
  the processes by which Grid applications
  contribute to the creation and delivery of
  information and knowledge.

Web services

• Instantiation of service-oriented model
• XML Protocol
• Web Services Description Language
• Universal Description Discovery and Integration
• Workflow description
• Web Services Flow Language
• XLang
• Other proposals emerging
• Note relationship to agent-based computing
• Open Grid Services Architecture

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

26
Vision

• 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.
• To achieve this we need to bring together
• Grid computing
• Service-oriented architectures
• Semantic Web
• RDF
• Knowledge technologies

28
Motivation for Semantic Grid activity

• Gap between vision of e-Science and current
  endeavours
• Three layer model compelling but much hand-waving
  about knowledge layer
• Concern about scalability assumptions
• Lack of holistic approach Grid starting at
  socket on wall
• Need for universal architecture
