摘要
In this paper the spatio-temporal data mining is studied by adopting the ontology theory. The method of spatio-temporal data mining based on ontology is presented and a new spatio-temporal forecasting model based on ontology is designed The model uses two measures of spaitio-temporal autocorrelation: spatio-temporal adjacency matrix and spatio-temporal contiguity measure. We use this model in the forecast about medium and long term coarse granularity in the railway passenger flow: and the results show that using the method of spatio-temporal forecasting based on ontology can obtain a good forecasting precision.
