Toward Trustworthy Adjustable Autonomy and Mixed-Initiative Interaction in KAoS

Trust is arguably the most crucial aspect of agent acceptability. Many aspects of trust can be addressed through policy. Policies are a means to dynamically regulate the behavior of system components without changing code or 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. In this paper we describe some important dimensions relating to autonomy and give examples of how these dimensions might be adjusted in order to enhance performance of human-agent teams. We then offer a definition of mixed-initiative interaction and give examples of relevant policies. We introduce Kaa, the KAoS adjustable autonomy component. Finally, we provide a brief comparison with two other implementations of adjustable autonomy concepts.
