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
AKT Workshop January 2001 3
Collaboratory Concept
“A centre without walls in which the nation’s 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
AKT Workshop January 2001 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
AKT Workshop January 2001 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
AKT Workshop January 2001 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.
AKT Workshop January 2001 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
AKT Workshop January 2001 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.

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”

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

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
