Abstract:

Traditional behavior-driven spatio-temporal data models mainly focus on the spatial movement property of an spatio-temporal object. However, they ignore the changes of attributive characteristics and relational properties caused by the behavior. As a result, the behavior-driven mechanism—an important feature in the pan-spatial information—has not been adequately investigated. In this paper, the spatio-temporal behavior was comprehensively investigated from the following aspects: firstly, the definition of the behavior was provided and the necessity of taking the behavior as one of the tuples of spatiotemporal ontology was demonstrated; secondly, the behavior was partitioned as 4 categories according to the changed features, including spatial behavior, attributive behavior, relational behavior and composite behavior; thirdly, definitions of the four behavior types and their corresponding formalized descriptive methods were proposed; finally, the behavior-driven mechanism in the spatio-temporal ontology was studied. This research lays a theoretical foundation for the study of spatio-temporal object model under the behavior-driven mechanism.
