Ontology based approach for E-Learning in concurrent enterprising

The paper proposes an ontology-based approach to implement E-Learning within a Collaborative Enterprise environment having a large base of applicability for engineering sciences. The approach is based on a new holistic model - the E-Learning Cube - conceived as tool for better understanding and characterization of the basic principles and mechanisms of E-Learning, for efficient use of the underlying infrastructure. The main components of a formal ontology are covered: conceptualization in the form of an abstract model, explicit definition through a vocabulary, formalization using the XML language and sharing ability in terms of capturing consensual knowledge.
