Abstract

To solve the problem of data-sharing between multi-source data for the reason of semantic heterogeneity, paper analysis the problem of semantic heterogeneity and propose a solution for it based on ontology, besides, paper take this solution to reality via VC++ 6.0 and have constructed the model of ontology by Protege, completed the mapping table and the new coding system, to deal with the semantic gulf between chart and map, solution has been used in national 863-project.
