Several works provide an overview of the use of semantic descriptions of 3D content in artificial intelligence systems. The idea of semantic description of 3D worlds has been summarized in27. In 28, a review of the main aspects related to the use of 3D content in connection with the semantic web technologies has been provided. In29, diverse issues arising from combining AI and virtual environments have been reviewed. In30, abstract semantic representations of events and actions in AI simulators have been presented. In31,32, a technique of incorporating knowledge in VR applications, a framework for decoupling components in real-time intelligent interactive systems with ontologies and a concept of semantic entities in VR applications have been discussed.
