This paper describes how a multi-agent, intelligent learning environment can provide adaptive tutoring based on learner modelling through Web Services. The system is called Web F-SMILE and is meant to help novice users learn how to manipulate the file store of their personal computer. The system has assigned an agent, called Learner Modelling (LM) Agent, to constantly observe the user and colle...

There have been signi®cant advances in the theory of goal programming (GP) in recent years, particularly in the area of intelligent modelling and solution analysis. The intention of this paper is to provide an overview of these developments, to detail and assess the current state-of-the-art in the subject, and to highlight areas which seem promising for future research. Modelling techniques suc...

Possibilistic Defeasible Logic Programming (P-DeLP) is a logic programming language which combines features from argumentation theory and logic programming, incorporating as well the treatment of possibilistic uncertainty and fuzzy knowledge at object-language level. Defeasible argumentation in general and P-DeLP in particular provide a way of modelling non-monotonic inference. When modelling i...

This article presents the iTransIT framework for building context-aware pervasive services in large-scale ambient environments. The iTransIT framework provides an architecture for conceptually integrating the independent systems underlying an ambient environment and a data model for capturing the contextual information generated by these systems. The data model is based on a hybrid approach to ...

WEAR is a Web-based authoring tool for Intelligent Tutoring Systems in Algebra related domains. Apart from modelling the student which is a common practice in almost all ITSs and ITS authoring tools, WEAR deals also with modelling the other class of its users: the instructors. Student and instructor models in WEAR interact with each other by exchanging information. This is in favour of both cla...

extending the export of high technology-based products is one of the most important goals of long term strategy of the country’s export development. in the present study, the main structures influencing the success of exportation through intangible resources (market orientation and entrepreneurial orientation) and the role of dynamism of export target market are investigated by considering the ...

Computer modelling is regarded as an important investigative tool in the formulation of correct guidelines and effective environmental policies for estuaries. Its ability in revealing important aspects of the estuarine dynamics under different conditions has provided strong motivation for the use and success of this approach. However, computer models are normally developed for specific cases, w...

Games have been widely used as an application for Artificial Intelligence techniques because of their simplicity and well-defined rules but in the other hand, for their huge range of possible and complex strategies to reach the final objective. In the last years, Artificial Intelligence study applied to games has focused more in games with incomplete information and non-deterministic games wher...
