Business process modelling and workflow process execution are often conducted in diverse environments and described using diverse process definition languages. Such systems often underpin distributed collaboration systems, but there is a current need to allow developers to use existing and familiar design methodologies and tools to design these systems.(More)
Previous experiments with animals and young children have shown that discriminations based on the presence versus absence of a single feature are learned more easily when the feature appears on reinforced rather than nonreinforced displays. Six experiments demonstrated an analogous effect in college students, across a range of stimulus materials, general(More)
Formal Concept Analysis (FCA) is a concept clustering approach that has been widely applied in ontology learning. In our work, we present an innovative approach to generating information context from a tentative domain specified scientific corpus and mapping a concept lattice to a formal ontology. The application of the proposed approach to Semantic Web(More)
Existing software systems designed to support learning do not adequately provide for vicarious learning in a cross-institutional collaborative environment. We have developed an architecture based on role-based access control, which provides the necessary security, robustness, flexibility, and explicit formulation of policy. Such an architecture is general(More)
The concept of the Virtual Software Corporation (VSC) has recently become a practical reality as a result of advances in communication and distributed technologies. However, there are significant difficulties with the management of the software development process within a VSC. The main problem is the significantly increased communicational complexity of(More)
