Events are centric to multimedia observation systems, which are meant to capture and process the sensory data and provide decisions about the events occurring in the environment. There are various granularities at which the events occur. For instance, an event can occur for a short time (a few seconds) or over a longer period of time (several minutes). Moreover, multiple events can occur simultaneously as well as they may have relationship with each other. Given the complexity of events, it is important to have an event representation model that can describe events at different levels. This paper presents a hierarchical model for event representation targeted to multimedia observation application. The proposed model defines events at three levels: transient, atomic and compound; and describes how the events at one level are mapped to another level. Moreover, the model also provides explicit representations for three types relationships between events: temporal, causal and spatial. The experiments validate the utility of the proposed model.
