Concept maps are an effective way of representing a person's understanding of a domain of knowledge. Technology can further help by making it easy to construct and modify that representation, to manage large representations for complex domains, and to allow groups of people to share in the construction of the concept maps. CmapTools is a software… (More)
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)
Information visualization has been a research topic for many years, leading to a mature field where guidelines and practices are well established. Knowledge visualization, in contrast, is a relatively new area of research that has received more attention recently due to the interest from the business community in Knowledge Management. In this paper we… (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.
Theorists and practitioners propose collaborative learning as a recommended methodology within constructivist environments. Concept mapping in particular has been shown to be an effective tool to support collaboration among students. However, seldom are teachers and students provided with the appropriate communication and collaboration tools, many of which… (More)
Policies are a means to dynamically regulate the behavior of system components without changing code nor requiring the cooperation of the components being governed. By changing policies, a system can be continuously adjusted to accommodate variations in externally imposed constraints and environmental conditions. KAoS policy and domain services rely on an… (More)
