Research on Geo-event Ontology Construction Oriented Task

It is difficult to organize the spatial information according to geographic events in the existed system. And the system can´t provide the users spatial information correlative to event disposal on its own initiative. Analyzing the method oriented task and centering about the task, a feasible means is introduced in this paper to be used to construct Geo-event ontology to serve the semantic retrieval, which can dispose the semantic heterology between different geographic information source, predigest the course of ontology construction and improve the efficiency of using ontology so as to redound to the distributed spatial share.
