Business interaction is a significant aspect of intelligent workflow systems, which are envisaged to deal with dynamic and interorganisational environments. However, automating business interaction in an intelligent way is not an easy task. To address this issue, this paper presents an ontological approach for modelling business interaction. The developed meta-model can support the process of a...

In this paper, we present technologies and techniques used in web-based intelligent educational systems (WBIESs). As WBIESs we consider either web-based intelligent tutoring systems (ITSs) or adaptive hypermedia education systems (AHESs) incorporating intelligent techniques. We present technologies and techniques for all the three basic components of a WBIES: the domain knowledge, the student m...

The aim of this document is to develop a conceptual architecture which can be used as a common language in discussions of the role of student modelling in intelligent learning environments. The architecture attempts to integrate empirical, computational and theoretical aspects of the problem. The architecture, christened DORMORBILE (a DOmain, Reasoning, MOnitoring and Reflection Basis for Intel...

Intelligent agent systems have been the subject of intensive research over the past few years; they comprise one of the most promising computing approaches ever, able to address issues that require abstract modelling and higher level reasoning. Virtual environments, on the other hand, offer the ideal means to produce simulations of the real world for purposes of entertainment, education, and ot...

Geometry will play a central role in the development of intelligent robotic systems. We describe a geometry engine, called robmod, that has been designed specifically for intelligent robotics applications. robmod is usable both as a geometric modelling system, based on the constructive solid geometry paradigm, and as a geometry engine that can be interrogated by programs that are reasoning abou...

This paper addresses the problem of evaluating students’ answers in intelligent tutoring environments with mixed-initiative dialogue by modelling it as a textual entailment problem. The problem of meaning representation and inference is a pervasive challenge in any integrated intelligent system handling communication. For intelligent tutorial dialogue systems, we show that entailment cases can ...

This memo presents current research in our laboratory. We address the following research topics: 1. Semantics-based assessment of nonmonotonic entailment methods for actions and change. 2. Implementation techniques for nonmonotonic entailment methods. 3. Algorithmic methods for planning and temporal reasoning. 4. Hybrid modelling of physical systems. 5. Design methodology for intelligent autono...

A Curious Place is modelled on the concept of an intelligent room, with an added capacity for behaving in a curious manner. Intelligent rooms are responsive physical spaces in which human activities are monitored and responses generated which facilitate or augment these activities. Recent trends in intelligent agent research towards intrinsically motivated learning agents allow physical places ...
