The success of Net-Centric Operations and Warfare (NCOW) depends upon the ability of net-centric environment (NCE) users both human and automated to readily discover useful information and services. Effective discovery requires, in turn, good semantic metadata tagging (i.e., indexing the functions of the services). Good tagging reflects the contextual relationships among the discoverable artifacts. It derives its value from the soundness and intuitiveness of its underlying approach to information and services classification. Unfortunately, classification soundness is mostly in the eye of the beholder, particularly for services that can be deployed for many different purposes, and not all necessarily foreseen by their initial developers. Ultimately, therefore, what is needed for more rapid and effective tagging and discovery is a services classification approach that accommodates multiple perspectives as to what constitutes a natural and intuitive characterization, plus tools that enable NCE users to take advantage of these capabilities without being overwhelmed by the sheer multiplicity of different classification perspectives. This paper presents a proposed structure for the semantic metadata that we believe will facilitate service and information discovery in the NCE, and will easily accommodate use by intelligent agents., The original document contains color images.

We have developed a method and prototype program for assisting two experts in their attempts to construct a single, consensus knowledge base. We show that consensus building can be effectively facilitated by a debugging approach that identifies, explains, and resolves discrepancies in their knowledge. To implement this approach we identify and use recognition and repair procedures for a variety of discrepancies. Examples of this knowledge are illustrated\\ with sample transcripts from CARTER, a system for reconciling two rule-based systems. Implications for resolving other kinds of knowledge representations are also examined.
