Method, device and equipment for constructing semantic-rich event spatio-temporal data model

The invention relates to a method, a device and equipment for constructing a rich semantic event spatio-temporal data model. The method comprises the steps of performing hierarchical division on events according to rich semantic event features of the events and event composition complexity, constructing an event hierarchical structure consisting of the events and entities, and obtaining rich semantic event features of elements in the event hierarchical structure and semantic logic relationships among the elements; from an object-oriented angle, abstracting the rich semantic event characteristics of each element into different classes, and constructing a rich semantic event spatio-temporal data model of the event by taking the different classes as nodes and taking a semantic logic relationship between the different classes as edges by adopting a directed graph theory so as to carry out event modeling expression. By adopting the method, the hierarchical structure of event development can be aggregated according
