Abstract

The Intelligence Community and other analytic-focused communities are developing and implementing large knowledge bases and semantic-based systems. These systems require new activities for managing the ontological underpinning of these systems, including a range of tasks from supporting domain description and evolution to integrating multiple source of semantic information. Beyond the role of the analyst or the traditional data base administrator, the role of the knowledge manager as the point of focus for such activities is growing in prominence. We are developing methods and tools to provide an analytical ability for the display and management of ontological systems, rooted in the formal properties of semantic relations in semantic graphs, and the semantic hierarchies in which they are valued. We describe methods for display, integration, and management of ontological resources to support the emerging Analytical Knowledge Manager with the AKEA tool.
