In this thesis, a system, called Ontology-Based Spatio-Temporal Video Management System
(OntoVMS) is developed in order to supply a framework which can be used for semantic
data modeling and querying in video files. OntoVMS supports semantic data modeling which
can be divided into concept modeling, spatio-temporal relation and trajectory data modeling.
The system uses Rhizomik MPEG-7 Ontology as the core ontology. Moreover ontology
expression capability is extended by automatically attaching domain ontologies. OntoVMS
supports querying of all spatial relations such as directional relations (north, south ...), mixed
directional relations (northeast, southwest ...), distance relations (near, far), positional relations
(above, below ...) and topological relations (inside, touch ...) / temporal relations such
as starts, equal, precedes / and trajectories of objects of interest. In order to enhance querying
capability, compound queries are added to the framework so that the user can combine simple
queries by using " / (" / , " / )" / , " / AND" / and " / OR" / operators. Finally, the use of the system is
demonstrated with a semi-automatic face annotation tool.
