In this paper, we describe our initial implementation of the KAoS policy and domain services. While initially oriented to the dynamic and complex requirements of software agent applications, the services are also being adapted to general-purpose grid computing and web services environments as well. The KAoS services rely on a DAML description-logic-based(More)
To increase the assurance with which agents can be deployed in operational settings, we have been developing the KAoS policy and domain services. In conjunction with Nomads strong mobility and safe execution features, KAoS services and tools allow for the specification, management, conflict resolution, and enforcement of DAML-based policies within the(More)
D espite rapid advances in Web Services, the user community's demanding requirements continue to outstrip available technology solutions. To help close this gap, Semantic Web Services advocates are defining and implementing many new and significant capabilities (www.swsi.org). These new capabilities should more fully harness Web Services' power through(More)
Policies are being increasingly used for automated system management and controlling the behavior of complex systems, allowing administrators to modify system behavior without changing source code or requiring the consent or cooperation of the components being governed. Past approaches to policy representation have been restrictive in many ways. By way of(More)
Coordination is an essential ingredient of joint activity in human-agent-robot teams. In this paper, we discuss some of the challenges and requirements for successful coordination, and briefly how we have used KAoS HART services framework to support coordination in a multi-team human-robot field exercise.
Several research groups have grappled with the problem of characterizing and developing practical approaches for implementing adjustable autonomy and mixed-initiative interaction in deployed systems. However, each group takes a little different approach and uses variations of the same terminology in a somewhat different fashion. In this chapter, we will(More)
This paper outlines a preliminary perspective on teamwork and adjustable autonomy in groups involving a mix of humans and autonomous agents. Unlike other approaches to agent teamwork, a human-centered perspective to human-agent interaction is used. The paper describes how we are integrating the Brahms and KAoS agent frameworks in order to model and simulate(More)
In this article we introduce KAoS, a policy and domain services framework based on W3C's OWL ontology language. KAoS was developed in response to the challenges presented by emerging semantic application requirements for infrastructure, especially in the area of security and trust management. The KAoS architecture, ontologies, policy representation,(More)
Because ever more powerful intelligent agents will interact with people in increasingly sophisticated and important ways, greater attention must be given to the technical and social aspects of how to make agents acceptable to people [87]. The technical challenge is to devise a computational structure that guarantees that from the technical standpoint all is(More)
