The paper describes an agent-based system, MEDICAL_MAS, developed for medical diagnosis. The architecture proposed for the system includes mainly two types of agents: personal agents and information searching agents. Each type of personal agent corresponds to the humans involved in the medical diagnosis and treatment process (i.e. the patient, the physician, the nurse). The information searchin...

Emerging technologies, such as intelligent agents, avatars, and distributed environments offer new opportunities for the improvement of business games used for training decision makers. The advent of these technologies also creates new challenges to game developers and training consultants. We investigate these opportunities and offer suggestions on how to better address technical and pedagogic...

A formal, computational model is proposed for navigating among the bureaucratic requirements relating to social services and electronic commerce. This model is based on a notion of intelligent agents, called messengers, that visit 'regimes' -formalized electronic front offices -of these agencies, and assemble the various requirements into a customized procedure for the client. On the client's a...

In this paper, we study the significance of the cognitive capacity in the context of double auction experiments. These experiments are then simulated using artificial agents in an agent-based modeling environment, and the results are compared with the results from human subjects.

Although representation of physical environments and behaviors will continue to play an important role in simulation-based training, an emerging challenge is representation of virtual humans with rich mental models (e.g., including emotions, trust) that interact through conversational behaviors as well as physical ones. The motivation for such simulations is training soft-skills such as leaders...

Criminal behaviour exists in many variations, each with its own cause. A large group of offenders only shows criminal behaviour during adolescence. This kind of behaviour is largely influenced by the interaction with others, through social learning. This paper contributes a dynamical agent-based approach to simulate social learning of adolescence-limited criminal behaviour, illustrated for a sm...

* 0-7803-7952-7/03/$17.00  2003 IEEE. Abstract – Intelligent Tutoring Systems are meant to provide individualised tutoring to students by adapting the teaching material to their specific needs and abilities. However, their development is a hard task and the endresult is difficult to evaluate. In this paper we present a novel approach for the evaluation of these systems, which relies on an agen...

This paper formalizes a well-known psychological model of emotions in an agent specification language. This is done by introducing a logical language and its semantics that are used to specify an agent model in terms of mental attitudes including emotions. We show that our formalization renders a number of intuitive and plausible properties of emotions. We also show how this formalization can b...

Production and conflict models have been used over the past 30 years to represent the effects of unproductive resource allocation in economics. Their major applications are in modelling the assignment of property rights, rentseeking and defense economics. This paper describes the process of designing an agent used in a production and conflict model. Using the capabilities of an agent-based appr...

This paper describes the methodology of an intelligent agent for building a self-adaptive course on the Web. An important task, therefore, is to combine adaptability with the learner-driven course in order to get a self-adaptive mechanism. For this, we have suggested a new structure for a web course. Based on this structure, we have suggested a new method to evaluate the granularity level of ea...
