The Ontology Web Language (OWL) provides a powerful framework for describing the semantics and constraints of a particular domain described in RDF. Along with that power comes the...
We study the computational complexity of reasoning with global constraints. We show that reasoning with such constraints is intractable in general. We then demonstrate how the sam...
This paper presents the conception, the design and a prototype of a virtual reality system for learning and maintenance training of Hydroelectric Generating Unit (HGU). The system...
During computer-mediated synchronous collaboration there is need for supporting reflection of the partners involved. In this paper we study techniques for determining the state of ...
