Rules and Implementation for Generating Ontology from Relational Database

On the purpose of generating ontologies from data sources on the practical application consideration, some rules on mapping relational database to ontologies are proposed. For the massive data stored in information systems, Master data management is brought in to make classification of data. Firstly, map the relation schema information into the ontology as concepts. Secondly, achieve the attributes, and map them to the properties in the ontology. Thirdly, analyze the constraints in databases, and modify the property constraints as needed in ontology. Then, extract the records into the ontology as individuals of concepts. At last, an implementation of generating ontologies from Mysql data source using the rules above is recommended as a case study of these rules. The result shows the rules are reasonable and complete in generating ontologies, and the method could be applied to the practical application.
