WE are working on software engineering issues of building software
systems that effectively utilize various Web-based resources, are adaptable
to changing needs and conditions in highly dynamic environments, and
allow end users to participate in the evolution of the software.

9. Main Approaches
• Task-oriented Service Computing
– Enable high-level software design (in multiple abstractions) with
primarily considering user tasks
– Support iterative and gradual development
– Improve reusability
– Enable application adaptability
– Enable service-privacy tradeoff
• Dynamic & Adaptive Software Engineering
– Improve correctness and context awareness
– Improve interoperability
– Support semi-automatic composition
– Enable end-user programming (mash-ups)

The Defense Software Component Grid (DSCG) is an
infrastructure that enables developers of defense
software to transparently and efficiently share and reuse
software components that are developed by different
developers for different information systems.
