Abstract

We propose to address the growing challenge of information overload in network-centric information systems through the development of an agent-based framework that improves the warfighter s awareness of critical information. In particular, we propose to enable adaptive information visualization in two ways: (1) exploiting simple profiles of the user s context to support intelligent discovery and relevance filtering of both geospatially tagged data and data with an unstructured geospatial component; and (2) employing a fire and forget server-side agent to reduce the demand on potentially constrained client devices operating under less than ideal network conditions. We also propose to utilize the context and existing workflow of the warfighter to adapt the visualization, and streamline user interfaces to support the need to markup and provide feedback on this data. By exploiting the unique characteristics of geospatial data and task domain knowledge, our proposed system, Milieu, will provide a much better fit to the capabilities and requirements of the warfighter than general purpose information visualization technologies can. Phase I will prove the feasibility of our overall approach by evaluating the proposed capabilities with the construction of a limited prototype.
