Heterogeneous Spatial Information System Semantic Interoperability Based on Bayes Data Classification and Ontology

This paper presents a feasible scheme for ontology-based semantic interoperation between heterogeneous geographic information systems.The concepts matching of heterogeneous spatial information is obtained by the ontology,and the Bayesian classification technique is used to class the geo-ontology objects.By using this technique the semantic interoperation between the heterogeneous geographic information systems is obtained.
