Found in: IEEE Intelligent Systems
By Niranjan Suri,Andrzej Uszok,Rita Lenzi,Maggie Breedy,Jeffrey M. Bradshaw,Yat Fu,James Hanna,Vaughn T. Combs,Asher Sinclair,Robert Grant
Issue Date:January 2013
pp. 64-71
To bring the advantages of network-centric warfare to coalition warfighting, we must significantly improve our ability to quickly share critical information while still satisfying security requirements. Here, the authors explore a services-based approach t...
Knowledge-Based Approaches to Information Management in Coalition Environments
Found in: IEEE Intelligent Systems
By Andrzej Uszok,Larry Bunch,Jeffrey M. Bradshaw,Thomas Reichherzer,James Hanna,Albert Frantz
Issue Date:January 2013
pp. 34-41
The community of interest information-sharing model lets coalition partners publish and disseminate data in a controlled fashion. In this vein, the authors have extended the Phoenix information management system to improve document selection and filtering.
Policy-Based Governance within Luna: Why We Developed Yet Another Agent Framework
Found in: 2012 IEEE/WIC/ACM International Joint Conferences on Web Intelligence (WI) and Intelligent Agent Technologies (IAT)
By Larry Bunch,Jeffrey M. Bradshaw,Tom Eskridge,Paul J. Feltovich,James Lott,Andrzej Uszok,Marco Carvalho
Issue Date:December 2012
pp. 250-256
In this article, we explain our rationale for the development of Luna, a software agent framework. In particular, we focus on how we use capabilities for comprehensive policy-based governance to ensure that key requirements for security, declarative specif...
Demonstrating Selected W3C Policy Languages Interest Group Use Cases Using the KAoS Policy Services Framework
Found in: Policies for Distributed Systems and Networks, IEEE International Workshop on
By Andrzej Uszok, Jeffrey M. Bradshaw
Issue Date:June 2008
pp. 233-234
This demonstration will present policies and scenarios from selected W3C Policy Language Group use cases. The flexibility of the KAoS ontology-based policy services framework will be demonstrated by modeling the very diverse policies described in the use c...
New Developments in Ontology-Based Policy Management: Increasing the Practicality and Comprehensiveness of KAoS
Found in: Policies for Distributed Systems and Networks, IEEE International Workshop on
By Andrzej Uszok, Jeffrey M. Bradshaw, James Lott, Maggie Breedy, Larry Bunch, Paul Feltovich, Matthew Johnson, Hyuckchul Jung
Issue Date:June 2008
pp. 145-152
The KAoS policy management framework pioneered the use of semantically-rich ontological representation and reasoning to specify, analyze, deconflict, and enforce policies. The framework has continued to evolve over the last five years, inspired by both tec...
Trust Negotiation as an Authorization Service forWeb Services
