The AKT Script
  • The background
  • The AKTors
  • The context
  • The challenges
  • The assumptions
  • The technologies
  • The testbeds
  • The AKTors Club

5
History of the bid
  • EPSRC competition for computer-centric IRCs
    announced
  • Outline bid submitted May 1999
  • Full bid submitted Nov 1999 12120
  • London presentation Jan 2000
  • Awarded April 2000 412
  • Official start Oct 2000 for 6 years
  • Full amount awarded - 7.5 million

6
The AKTors
  • The Universities of Southampton (ECS), Aberdeen
    (CS), Edinburgh (CIS/AIAI), Sheffield (CS), the
    Open University (KMI)
  • Around 36 investigators and reseach staff

7
AKT The story so far
  • AKT0 infrastructure built
  • 1st Technical Workshop Jan 01
  • 2nd Technical Workshop June 01
  • 1st Town Meeting London 18-9-01

8
Context Definitions
  • Data raw uninterpreted bits, bytes and signals
  • Information data equipped with meaning
  • Knowledge information applied to achieve a
    goal, effect an action, make a decision

9
Context The Problem
  • We are drowning in information and starving for
    knowledge
  • Infosmog The condition of having too much
    information to be able to take effective action
    or make an informed decision
  • The deluge of data is overwhelming

Knowledge
Information
Data
10
Context Aspirations
  • getting the right information, to the right
    person/system, in the right form at the right
    time the provision of knowledge services
  • turning information into knowledge
  • in some cases turning data into enriched,
    annotated information
  • supporting the knowledge life-cycle

11
Context Supporting the Knowledge Life Cycle
12
Challenges Acquisition
  • Diversity of sources
  • Distributed nature
  • Problems of scale
  • Acquisition rationale and annotation
  • Incidental KA is the Holy Grail

13
Challenges Modelling
  • What to model?
  • How to model?
  • How enriched?
  • How personalised?

14
Challenges in the K Life Cycle Retrieval
  • Retrieval paradigms
  • Framing queries
  • Scope and extent of search
  • Nature of search

15
Challenges in the K Life Cycle Reuse
  • What does reuse mean
  • What can be reused
  • How to identify reuse options
  • How to model/capture for reuse

16
Challenges in the K Life Cycle Publishing
  • Dynamic document/content construction
  • Richly linked content
  • Integrating authoring, reviewing and presentation
  • Personalised presentation

17
Challenges in the K Life Cycle Maintainance
  • How to capture and model for maintenance?
  • What model of custodianship?
  • Change control, certification and
    re-certification
  • Decommissioning

18
Challenges to the IRC
  • Reconciling short, medium and long term
  • Achieving practical relevance
  • Maintaining quality over 6 years
  • Daring to be off the wall

19
Assumptions AKT is interdisciplinary
  • Knowledge Engineering
  • WWW technology and standards
  • Multimedia Information Systems
  • Natural Language Processing
  • Agent Based Computing

20
Assumptions AKT meets Semantic Web
21
Assumptions AKT and Ontologies
  • Shared understanding or conceptualisation
  • set of concepts (e.g. entities, attributes,
    processes), their definitions and
    inter-relationships
  • Facilitate communication
  • Normative models
  • Inter-operability Sharing Reuse
  • Inter-lingua

Assumptions AKT aims to provide Knowledge
Services on the Semantic Web
  • Content with extensive meta data,information,know
    ledge
  • Services that exploit this enriched content

25
AKT KM and K Technology
  • Technology crucial to meet the challenges
  • Technology not 100 of the solution
  • Technology to be usable by diverse organisations
  • need to understand requirements
  • should not provide monolithic system
  • Aim to be a research locus for technologies to
    support knowledge services

26
Example work to date
  • Tools and methods to develop, build and maintain
    ontologies
  • Services for content annotation
  • Investigating web based inference engines
  • Integration of link services
  • Characterisation of ABus
  • Agents as knowledge services
  • Multimedia KA
  • Knowledge valuation

27
Challenges Test Beds
  • AKT Scientific KM
  • Rolls Royce Aerospace Supporting Design,
    Enriching objects
  • Unilever Knowledge Auditing
  • UK E-Science Grid Initiative

28
Definition of AKTors
Club Players Those companies who are
displaying an active interest in AKT. A named
contact from each company would have a named
contact from the AKT consortium. Each Player
would be asked to produce a web page, which
should be updated each year in order to remain on
the Players' list."Audience"Those companies
who have expressed an interest in AKT but are not
considered as being "active" (ie have not
produced a web page).An annual Town Meeting
will be held for the AKTors Club.
