An intelligent interface cannot just respond passively to its user’s commands and queries. It must be able to take the initiative in order to volunteer information, correct user misconceptions, or reject unethical user requests. To do these things, a system must be an intelligent agent. UCEgo is the intelligent agent component of UC (UNIX Consultant), a natural-language system that helps the us...

The perspective of modelling agents rather than using them for a specificed purpose entails a difference in approach. In particular an emphasis on veracity as opposed to efficiency. An approach using evolving populations of mental models is described that goes some way to meet these concerns. It is then ar gued that social intelligence is not mer ely intelligence plus interaction but should all...

In this paper we propose a computational model for implementing emotions in intelligent agents. Emotional behaviour is viewed as a complex mental behaviour directed towards a set of objects in response to changes in the agent’s environment. This mental behaviour is responsible for generating different types of mental objects: plans, goals, attitudes, and sub-emotions, which persist in the menta...

Intelligent agents have been applied to electronic commerce, promising a revolution in the way we conduct business, whether business-to-business, business-to-customer or customer-to-customer. This article gives a brief review of agent technologies involved in buying and selling, followed by lists of Internet e-commerce agents. Several agent-mediated electronic commerce systems are analysed in t...

The aim of this paper is to indicate and explore some of the possibilities of using agents in today’s and tomorrow’s law offices. The main function of agents is, in general, to support the user. In this case, a lawyer. To be able to support a practicing lawyer, however, not only is insight in daily practice required, but also understanding of practicing lawyers needs and desires. This position ...

This paper presents ongoing work in the definition of a contracting language, which can be used not only to specify agreed behaviour in service-oriented architectures but also for agentmediated systems. The contract clauses are based in deontic notions such as obligations, permissions and prohibitions. The language not only covers the contract document itself but several layers of communication...

Software intelligent agents, or simply agents, are one of the most important research areas in computer science and information technology. Plenty of work has been done on different aspects of agents development. This paper presents a survey of research activities in the development of intelligent agents. The survey categorizes the agent related work into three main theoretical based areas: (1)...

Interacting with intelligence in an ever-changing environment calls for exceptional performances from artificial beings. One mechanism explored to produce intuitive-like behavior in artificial intelligence applications is emotion. This chapter examines the engineering of a mechanism that synthesizes and processes an artificial agent’s internal emotional states: the Affective Space. Through use ...

A definition of language is proposed in which language is a lowbandwidth channel that can increase agent rewards in a reinforcement learning setting, and in which agents can learn to produce language and teach it to other agents. Societies of agents are being modeled by economists to understand economic instability and other non-equilibrium phenomena. I hypothesize a divergent distribution of i...

Computer traffic simulation is important for making new traffic-control strategies. Microscopictraffic simulators can model traffic flow in a realistic manner and are ideal for agent-basedvehicle control. In this paper we describe a model of a reactive agent that is used to control asimulated vehicle. The agent is capable of tactical-level driving and has different driving styles.<l...
