Domain Ontology, Probability and Virtual Reality

Ontologies are powerful instruments for high–level description of concepts, especially for Semantic Web applications or features classification. In some cases, Ontologies have been used to create high–level description of the Virtual Worlds objects in order to simplify the definition of a Virtual Reality. In this paper, we will describe an hybrid methodology that, starting from a domain Ontology, provides the basis for the creation of a Virtual Reality that could train workers to correct use of protection tools. In addition, starting from real data, we generate a Bayesian Network that calculates the probability of death or injuries in case of misconduct.
