Directing Agent Communities: An Initial Framework
This paper presents a framework for directability of a community of agents by a human supervisor that focuses on three dimensions: adjustable agent autonomy, strategy preference, and community-level constraints.
-
Human Directability of Agents
This paper presents a framework for the directability of agents, in which a human supervisor can define policies to influence agent activities at execution time.

Finding Consensus in Speech Recognition: Word Error Minimization and Other Applications of Confusion Networks
We describe a new framework for distilling information from word lattices to improve the accuracy of speech recognition and obtain a more perspicuous representation of a set of alternative hypotheses.
