Heterogeneous Enterprise
Problems
• Achieving and maintaining systems interoperability
– Incompatible data, data models, services, and applications.
• Challenges exist in sharing information across domains
– Insufficient information sharing capabilities that allow
effective information exchange across multiple communities
of interest, security enclaves, organizational boundaries, and
infrastructures.
• Policy conflicts can hamper efficiency and effectiveness of joint
and coalition operations
– Insufficient means to encode policies for semi-autonomous
interpretation, negotiation, enactment, and enforcement.

Heterogeneous Enterprise
Needs
• Systems that interoperate (even in the face of change)
– Compatible data, data models, services, and applications.
• Cross-domain information sharing
– Information sharing capabilities that allow effective
information exchange across multiple communities of
interest.
• Policy specification and enforcement
– Tools and mechanisms to encode policies for semiautonomous interpretation, negotiation, enactment, and
enforcement.

Situational Awareness
Problems
• Maintaining situational awareness is difficult if the necessary
collection assets cannot be rapidly deployed and connected
– Inability to autonomously manage and network theatre assets
for rapid situational awareness.
• Correlating and integrating vast amounts intelligence data
remains a hard problem
– Particularly as new sensor systems and platforms come online, it is difficult to effectively correlate, disambiguate,
deconflict and combine sensor and human intelligence data
into a common contextual model.
• Human interpretation of intelligence information is time
consuming and sometimes error-prone
– Insufficient ability to rapidly interpret vast amounts of
intelligence information.

Situational Awareness
Needs
• Enabling situational awareness
– Ability to autonomously manage and network theatre assets
for rapidly achieving situational awareness.
• Intelligence data fusion
– Ability to effectively correlate, disambiguate, and combine
sensor and human intelligence data into a common context
and information model.
• Rapid interpretation of intelligence
– Ability to rapidly interpret vast amounts of intelligence
information.

Effects-Based Operations
Problems
• Ensuring that critical command and control systems continue to
operate as needed
– Information systems require a high level of human
intervention to keep them operational during mission
preparation and execution.
• It is difficult to synchronize the application of diverse, distributed
forces in time-critical situations
– Execution management capabilities are challenged in near
real-time conditions in order to dominate an adversary and
achieve the desired effects.
• Rapidly assessing that combat operations are achieving the
desired effects is a challenge
– Real-time effects-based assessment of combat operations is
problematic.

Effects-Based Operations
Needs
• Command and control systems resource management
– Self-aware systems that can learn, adapt, and heal
themselves.
• Rapid employment of agile forces
– Near real-time, dynamic synchronization of the employment of
distributed forces to dominate an adversary and achieve
desired effects.
• Real-time effects assessment
– Provisioning of real-time effects-based assessment of combat
operations.

Conclusions
• Semantic technology holds great promise in
addressing many of the problems and needs identified
•
Additional investments are needed to mature the
technology and make it easier to use and deploy in
military applications
•
An incremental approach toward widespread adoption
seems likely – some semantic technologies will gain
traction sooner than others
•
We (academia, industry, government) need to do it
together, and progress is rapidly being made from a
historical perspective
