基于UML类图的模糊时空数据建模

bstract: Fuzziness widely exists in many spatio-temporal applications. The existing spatio-temporal data models lack the ability to describe and represent the internal mechanisms or semantic relation of fuzzy spatio-temporal objects. After investigating the semantics of fuzzy spatio-temporal data, a formal definition about fuzzy spatio-temporal data model is proposed. On this basis, the UML data model is extended to express fuzzy temporal and spatial data. Finally, the potential usefulness of our proposed method is demonstrated with an example.)
