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

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
