Abstract Expressive facial animation synthesis of human like characters has had many approacheswith good results. MPEG-4 standard has functioned as the basis of many of thoseapproaches. In this paper we would like to lay out the knowledge of some of thoseapproaches inside an ontology in order to support the modeling of emotionalfacial animation in virtual humans (VH). Inside this ontology we will present MPEG-4facial animation concepts and its relationship with emotion through expression profilesthat utilize psychological models of emotions. The ontology allows storing, indexing andretrieving prerecorded synthetic facial animations that can express a given emotion. Alsothis ontology can be used a refined knowledge base in regards to the emotional facialanimation creation. This ontology is made using Web Ontology Language and the resultsare presented as answered queries.
