  3. Background Studies • P. Feltovich, et al., Policy and Social Barriers to New Military Information Technologies • S. Bockman, et al., An Empirical Study of Barriers to Information Sharing • M. Johnson, et al., Applying Semantic Technologies… • In collaboration with Eric Heilman, Joe Bernard, and Eric Roles

  4. Messages • Many interesting devices and applications to aid in the collection and sharing of ASCOPE information are appearing • Challenges outlined yesterday show that, in addition, more attention needs to be focused on making the information and networks “smarter” • Semantic technologies to quickly standardize and “tag” the information • Advanced policy frameworks to increase the relevance of the information shared • Dissemination services to overcome problems of limited bandwidth and intermittent connectivity

  5. Challenges Mentioned Problems Approach Semantic technologies (OWL ontologies) to aid in classification and reduce duplication Runtime extensibility of OWL ontologies and software components Policy-governed information exchange Policy-based information scoping • Multiple users creating entities for the same event; no standard for entity classification • Limited customization of visualizations and analytics • Wasting bandwidth with irrelevant information • No way to control information sharing

  6. Challenges Mentioned Problems Approach Semantic “tagging” allows aggregation of data for meaningful metrics Dissemination services, combined with policy, to prioritize information sharing Dissemination services to support opportunistic data harvesting • Inadequate metrics on effectiveness of information sharing • Departures on short notice; useful information not available until “outside the wire” • Spread out forces and frequent disconnection

  7. Information Gathering and Sharing Demonstration • Based on our previous studies and interaction with soldiers • Information and network “smarts,” not devices or applications • Mature, flexible, pluggable, scalable, extensible architecture
