We are investigating the cooperative behavior of intelligent agents in a large group. A cooperative intelligent agent is a user's personal consultant that can take care of problems the user got, and solve them either by itself or via cooperation. We have proposed a twin-base (cooperator-base U task-base) agent modeling technique for individual agents to monitor activities of the others in order...

Cooperative learning has been used effectively at the elementary and secondary levels, but it has only recently found its way to the college level. Therefore, in colleges, universities and work places throughout the world, tremendous efforts are underway to move from a lecture-based approach to more active, cooperative learning activities. This study investigates the effect of cooperative learn...

This paper provides results of experiments on the use of domain knowledge models to recognize military groups, units, and activities from input track data. The group, unit and activity assessments are provided in the form of a situation estimate which is evaluated against ground truth. Our experimental architecture allows us to evaluate the quality of the resulting situation estimate as a funct...

This paper presents a sketch of a specification language whose basic notion is activities taking place in special environments – habitats – designed to support these activities. The purpose of the language is to facilitate specification of pervasive technologies that are distributed in space, with special emphasis placed on their cooperative aspects.

Learning in a dynamic, uncertain, multi-agent setting is a challenging task. In this work, we demonstrate techniques to convert noisy run-time activity into procedures useful for future problem-solving activities. The cooperative procedures created by this conversion process are stored in an agent resource called collective memory. We show how this memory enables agents to learn cooperative pro...

Across all cultures, humans engage in cooperative activities that can be as simple as preparing a meal or sharing food with others and as complex as playing in an orchestra or donating to charity. Although intraspecific cooperation exists among many other animal species, only humans engage in such a wide array of cooperative interaction and participate in large-scale cooperation that extends be...
