Organizations must establish processes for managing knowledge across boundaries because of the specialized and task-dependent forms of knowledge required to deliver products and services. To address this challenge an integrative framework is developed that identifies and integrates the value of…

This paper presents a version of frames suitable for representing knowledge for a class of reconition problems. An initial section gives an intuitive model of frames, and illustrates a number of desirable features of such a representation. A more technical…

Over the next five years, computer games will find their way into a vast number of American homes, creating a unique educational opportunity: the development of "computer coaches" for the serious intellectual skills required by some of these games. From…

This thesis analyzes how the Auto-ID technology and information infrastructure will change the management and distribution of pharmaceutical products within the health care industry by enabling item level product traceability functionality. The complexity of the health care industry is steadily…

Creating common ground in a community of people who do not all know each other is a chicken-and-egg problem: members do not share enough common ground to support the kinds of conversations that help build it. "Folk Computing" technology is…

This paper analyzes the suitability of reinforcement learning (RL) for both programming and adapting situated agents. We discuss two RL algorithms: Q-learning and the Bucket Brigade. We introduce a special case of the Bucket Brigade, and analyze and compare its…

We develop a novel autonomous control synthesis strategy called Phase Space Navigator for the automatic synthesis of nonlinear control systems. The Phase Space Navigator generates global control laws by synthesizing flow shapes of dynamical systems and planning and navigating system…

We develop a qualitative method for understanding and representing phase space structures of complex systems and demonstrate the method with a program, MAPS --- Modeler and Analyzer for Phase Spaces, using deep domain knowledge of dynamical system theory. Given a…

A key problem in model-based object recognition is selection, namely, the problem of determining which regions in the image are likely to come from a single object. In this paper we present an approach that extracts and uses color region…
