Community Semantics for Ultra-Scale Information Management

The U.S. Department of Defense (DoD) presents an instance of an ultra-scale information management problem: thousands of information systems, millions of users, billions of dollars for procurement and operations. Military organizations are often viewed as the ultimate in rigid hierarchical control. In fact, authority over users and developers is widely distributed, and centralized control is quite difficult – or even impossible, as many of the DoD core functions involve an extended enterprise that includes completely independent entities, such as allied military forces, for-profit corporations, and non-governmental organizations. For this reason, information management within the DoD must take place in an environment of limited autonomy, one in which influence and negotiation are as necessary as top-down direction and control.

This presentation examines the DoD’s information management problems in the context of its transformation to network-centric warfare The key tenent of NCW holds that “seamless” information sharing leads to increased combat power. We examine several implications of the net-centric transformation and show how each depends upon shared semantic understanding within communities of interest. Opportunities for research and for commercial tool development in the area of conceptual modeling will be apparent as we go along.
