【摘要】：基于行为驱动的传统时空数据模型只关注时空对象的空间运动行为,忽略了行为对时空对象属性、关系等的改变,导致行为对时空对象的驱动机制研究不足。时空行为是全空间信息系统表达的重要特征之一,为此,本文从以下几个方面阐述了时空对象的行为。首先,本文阐述3行为的定义及将行为作为时空本体的元组的必要性。其次,研究了时空对象行为的复杂性、可继承性及在时态上的延续性等特征。再次,根据行为的作用对象,将时空对象的行为分为空间行为、属性行为、关系行为及复合行为4类行为,并给出了上述4类行为的定义与形式化表达方式。最后,分析了时空本体中时空行为的驱动机制。通过时空行为分类及其在时空本体中的形式化表达研究,为基于行为驱动的时空对象构模奠定了理论基础。
[Abstract]:The traditional spatio-temporal data model based on behavior drive only pays attention to the spatial motion behavior of spatio-temporal objects and neglects the change of behavior to the properties and relationships of spatio-temporal objects, which leads to the lack of research on the driving mechanism of behavior to spatio-temporal objects. Spatiotemporal behavior is one of the important characteristics of the expression of full spatial information system. Therefore, this paper expounds the behavior of spatio-temporal objects from the following aspects. Firstly, the definition of three behaviors and the necessity of taking them as tuples of spatiotemporal ontology are discussed in this paper. Secondly, the complexity, inheritance and temporal continuity of spatiotemporal objects are studied. Thirdly, according to the action object of behavior, the behavior of spatio-temporal object is divided into four types: spatial behavior, attribute behavior, relational behavior and composite behavior, and the definition and formal expression of the above four kinds of behaviors are given. Finally, the driving mechanism of spatiotemporal behavior in spatio-temporal ontology is analyzed. Through the research of spatio-temporal behavior classification and its formal representation in spatio-temporal ontology, it lays a theoretical foundation for behavioral driven spatio-temporal object modeling.
