The control of multi{level cooperative dialogue is considered a diicult problem in knowledge based systems but may be easier to tackle in the more restricted domain of Intelligent Front Ends. This paper discusses the requirement for multi{level cooperative dialogue in IFE programs and describes several techniques for supporting this form of interaction, using examples from implemented systems.

An important property of intelligent agents is semi-understanding of desired tasks. We have designed an agent module referred to as Professional Description Assistant that is able to identify the corresponding job definition from a job description in textual form. Thus it plays a significant role in the advanced services of our EMA employment agent. By means of some standard and modified learni...

In this paper a dynamic perspective on concepts for intelligent agents is propagated. The discussion on the nature of concepts can be simplified to a dichotomy between objective/static and subjective/dynamic approaches. In the objective case, concepts are the same for all individuals. Under a dynamic perspective, concepts depend on different factors like the learning process, the environment, i...

Most legal tasks involve document preparation. Drafting effective texts is central to lawyering, judging, legislating, and regulating. How best to support that work with intelligent tools is an ancient topic in AI-and-Law circles. This article surveys the history and current state of document drafting software and associated theory. Present frontiers in both of those fields are identified, and ...

Computational agents can motivate people to change their behaviour towards energy use in a home setting. In this paper, we investigate the design and evaluation of the iParrot, an intelligent agent that helps to persuade family members to conserve energy in their home. The iParrot was designed as a concept in the form of a video prototype with two conditions. The results from the evaluation sho...
