Abstract. This paper proposes the use of ontologies to provide virtual environments with semantic information, that can be also used by intelligent virtual agents. We present our semantic architecture focusing on the ontology which mainly supports complex object representation and interaction. This approach helps the actors when sensing complex objects such as containers (e.g. cabinet, shelf, box) and it also allows them to interact with different sort of objects, looking at the class taxonomy defined by the ontology of the world. We finally show how the semantic information can be introduced in STRIPS based planners to enrich the actors activities that can be interesting for both narrative games and storytelling systems. 1 Introduction and related work Game narrative [4] and storytelling systems [2] have productively applied planning techniques to generate dynamic and interactive stories. Curiously, although these approaches are well known as knowledge intensive [2], no structure is normally
