AKT Review, Sept. 2003
AKT Integrated Feasibility Demonstrator
CoAKTinG partners (AKT subset)
Overview
Component approaches Edinburgh / Open U. / Southampton
Integration>> advances that would never have happened without this project <<
Conceptual Technical
Key contributions and future work
Beyond video conferencing…
collective sensemaking /
discussion capture
following through decisions/coordinating activities
synthesising artifacts
recovering information from meetings
awareness of agent status /
sense of ‘presence’virtual meetings
…integrating multiple modes of collaboration
‘Presence’ semantics
… as an aggregated view of an (object)’s dynamically changing attributes (Chakraborty, 2001)
Availability (“I’m logged on for a videoconference”) Preference (“Only my boss can interrupt me now”) Capability (“My device can accept video calls”) Location (“I’m in Munich… urgent calls only”)
awareness ofagent status /
sense of ‘presence’
Presence visualization
Beyond ‘buddy lists’
Geographic and conceptual maps
Other instant messaging features make it the most downloaded Jabber client
Compendium “I see what you’re saying”
Connecting ideas: visually, by sets, metadata, and hypertextually
Real time visual mapping of issues, ideas, arguments and decisions in meetings
Multimedia webs of resources and discussions Incremental formalization with shared ownership Free-form and template driven discussions
collective sensemaking /
discussion capture
Scenario Building: Mapping argumentsand decision rationale
Compendium: structured template
Compendium: meeting template
I-X Process Panels I-X environment: handling issues, performing
activities, placing constraints, adding annotations
Based on a synthesis-task ontology <I-N-C-A> Role in CoAKTinG: networked ‘To Do’ lists for
issue handling and activity tracking
following through decisions/coordinating activities
synthesising artifacts
I-X meeting action items Process Panel
HyStream
Continuous metadata
• Metadata annotation of continuous media
• e.g. Hystream project• application of open hypermedia to streamed,
temporal media• continuous link flows: link generation,
storage, synchronised transmission, delivery and resolution
Interim Results
Integration work
Conceptual Extending the AKT Reference Ontology Mapping and cross-fertilisation between two
issue-management ontologies Technical
Off-the-shelf Jabber-based integration 3 tools freely available for download Intelligent team rosta management Integration between Compendium,
I-X, BuddySpace, Meeting replay tool
Key Contributions• Support variable levels of formality in communication• Real time semantic annotation of discussions• Events ontology for e-Science collaboration• Context-driven collaboration tools
Conceptual integration:Extending the Reference Ontology
Extensions to support:• generation of multimedia presentations (e.g.
millisecond representations of time)
• meetings distributed across several (physical and virtual) locations
• exhibition of information objects as events (e.g. slides; videos; documents)
• meeting-specific (compound) information bearing objects (versions of resources used in meetings)
• annotation events (e.g. verbal comments, creation of Compendium nodes)
Conceptual integration: Issue-based ontologies
IBIS: Issue-Based Information System (optimised for synchronous discussion and mapping in Compendium) Issues, Positions, Arguments, Decisions, Reference
Nodes
<I-N-C-A> (optimised for asynchronous coordination of activities in I-X Process Panels) Issues, Nodes, Constraints, Annotations
Where appropriate, one brings in a Compendium template (e.g. I-X Plans) to support structured work
IBIS-inspired extensions to <I-N-C-A>
• Deontic questions - What should we do?
• Instrumental questions - How should we do it?
• Criterial questions - What are the criteria?
• Meaning or conceptual questions - What does X mean?
• Factual questions - What is X? or Is X true?
• Background questions - What is the background to this project?
• Stakeholder questions - Who are the stakeholders of this project?

Meeting replay by time, speaker, contribution to discussion, and decision
Future work The CSCW graveyard…
…users will consider any required adaptation a cost…services need to justify themselves
Semantics Co-existence and merging of issue ontologies Dynamic context for agents, processes and products
Meeting replay/navigation As the corpus grows, need for dynamic generation of
views across meetings and themes user interface and engineering challenges – poss. Equator collaboration
Towards hybrid semantic annotationhuman sensemaking + analysis/IE on the RDF repository
Domain testbeds Scientific project management (AKT)
Work with Comb-e-Chem e-Science project Dynamic e-Response emergency relief scenario
