The Evolving Problem
Assessing and digesting enormous
quantities of data
Developing an accurate threat or
situation assessment
Decision making
Assessing the result

Multitude of Data Sources
National SIGINT Assets
Tactical SIGINT Assets:
– Aircraft
– Unmanned Aerial Vehicles (UAVs)
– Ground-based Sensors
Nano and Micro-scale sensors
– Smart Dust
HUMINT
Open Source

Traditional View of Processing
Intelligence Data
The utility of a data
fusion system must be
measured by the extent
to which it supports
effective decision
making

Knowledge
Glut of Data “Problem”
Lots of data in multiple forms:
– COMINT
– SIGINT
– IMINT
– HUMINT
Data is not housed in a single
repository or data base
Not enough analysts
Collaboration limitations

Proposed Solutions
More:
– Pattern Recognition
– Machine Learning Methods
– Advanced Filtering
– Data Mining

Proposed Solution Fallacies
It is just a matter of “finding the
needle in the haystack”
Knowledge creation involves human
collaboration
Knowledge is inherently a human
product
The approach starts at the “wrong
end”

Strategies for Resolving the
Knowledge Creation Problem
Increase the bandwidth: Make
computer displays larger
Fly-by-wire: Use gaming techniques
to “physically” access data
Use multiple senses: Vision +
hearing + haptic

Strategies for Resolving the
Knowledge Creation Problem
Conserve analyst attention:
– Deliberate synesthesia – Transforming
data from one sensory domain to
another
– Use other techniques to focus the
attention of the analyst
Leverage the power of language
Focus on negative space

Strategies for Resolving the
Knowledge Creation Problem
Create cyber cognitive multipliers:
– “The Matrix Approach” – Agents in
cyber-space can replicate themselves
– Mixed teams of analysts, intelligent
team-based agents, and decisionmakers
Adapt to individual users: Interfaces
that learn the preferences of and “fit”
individual users

Recommendations
Develop two realistic scenarios and
associated data sets to test
strategies
Conduct some knowledge elicitation
from “real” analysts

Recommendations
Evaluate the effectiveness of
implemented tools using the Living
Laboratory approach
Transition selected tools to real
environments
