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)
A continuing problem in business today is the design of human—computer systems that respect how work actually gets done. The overarching context of work consists of activities, which people conceive as ways of organizing their daily life and especially their interactions with each other. Activities include reading mail, going to workshops, meeting with(More)
In this paper we report results of an informal field study of a software development team conducted during an eight week internship at the NASA/Ames Research Center. The team develops a suite of tools called MVP, and is composed of 31 co-located software engineers, who design , test, document, and maintain the different MVP tools. We describe the formal and(More)
OCAMS is a practical engineering application of multi-agent systems technology, involving redesign of the tools and practices in a complex, distributed system. OCAMS is designed to assist flight controllers in managing interactions with the file system onboard the International Space Station. The " simulation to implementation " development methodology(More)
This paper outlines the technical and social dimensions to a hypertext tool that has been successfully used in organizational settings to improve meetings, and capture group memory in real time. The approach derives from hypertext research systems from the mid-1980s-90s which sought to manipulate conceptual structures as hypertextual concept maps. However,(More)
W ork systems involve people engaging in activities over time—not just with each other, but also with machines, tools, documents, and other artifacts. 1 These activities often produce goods, services, or—as is the case in the work system described in this article—scientific data. Work systems and work practice evolve slowly over time. The integration and(More)
that they will function less like tools and more like teammates. 1–3 Many approaches to designing more team-like cooperation between humans and machines have been proposed, including function allocation, supervisory control, adaptive automation, dynamic task allocation, adjustable autonomy, mixed-initiative interaction—most recently regrouped under the(More)
where he manages the Brahms project on modeling and simulating work practice. His research interests are multiagent mod-eling languages and their application to the development of human-centered systems. Before joining RIACS, he was a member of the Work Systems Design group and the Expert Systems laboratory of NYNEX Science & Technology. He also developed(More)
– In this paper, we outline an approach to policy-based coordination in joint human-agent activity. The approach is grounded in a theory of joint activity originally developed in the context of discourse, and now applied to the broader realm of human-agent interaction. We have been gradually implementing selected aspects of policy-based coordination within(More)
