Technical ApproachMain Point

• Assembling Declarative Executable Models from
  components is an intuitive way for SMEs to author
  a knowledge base
• Building blocks of a knowledge base
• Combining building blocks by graph operations

4
Progress ReportJune - September 2000

• Partial Design
• End-to-end story board
• End-to-end design document
• Version 0.1 implementation

5
Partial Design

• UT/Boeing produced the virus infection scenario
  and a partial design showing concept compositions
• ISI and Boeing designed an example use of
  knowledge analysis in the virus infection scenario

6
End-to-end Story Board

• We extended the partial design to include an
  interaction manager, and explanation facility
• The E2E storyboard shows how a user would
  interact with the system and the role of various
  system components

7
End-to-end Design Document

• Capture the initial design
• Sketch out the vision for the Summer 2001 system
  and the steps needed to accomplish it
• Use of metaphors and analogy
• Define first cut APIs
• Define component experiments

Shaken 0.1

• E2E implementation of the virus infection
  scenario
• Exercises various system components
• Made the APIs more concrete
• Brought out the software integration issues more
  clearly
• Stepping stone to future extensions

• Use case for analogy
• Make the interaction smoother
• Extensions to the CMAP interface
• Acquiring taxonomic knowledge
• Acquiring problem solving knowledge
• Software integration issues
• Extensions to question asking
• Experiments with SMEs
• Representation and reasoning issues
