The Use of Domain Ontologies for the Virtual Scenes Management

摘要

In this paper, an object-oriented software system for the management of virtual scenes is presented. This system, called OntSceneBuilder, uses a domain ontology in order to obtain at least three benefits: accuracy, ease of content reuse and management of virtual scenes. The accuracy is ensured by default, since any ontology provides a precise specification of the concepts and their relations of a domain. Each concept is associated with 2D and 3D resources and a virtual artifact. The graph of the virtual artifacts forms a virtual scene of a virtual exposition. The paper also presents some models of the system development process, mainly realized during the analysis and design activities. Our aim was to analyze the OntSceneBuilder from the functional and interactional viewpoints and to create its software use case diagram. Furthermore, each software use case was designed from the structural and dynamical viewpoints. At the same time we also constructed the system software architecture. Some classes of the software architecture manage the concepts of the domain ontology associated with the topic chosen by user. The system has been experimented in the realization of virtual scenes of a virtual historic exposition.
