A rule-based ontology converting device for converting from relational database to an ontology instance and the method thereof

摘要

rules-based ontology conversion apparatus and method for converting a DB table in a relational database to ontology instances by the transformation rules relates to, table input unit for receiving the DB table; Receiving the input ontology Classes; Rule generation unit for generating a conversion rule for converting the DB table in the instance of the ontology class (the ontology instances); And, reads the entity from the DB table, in accordance with the conversion rule, includes a conversion entity generating the ontology instances corresponding to the entity, and wherein the first transformation rule to map the ontology class table in the DB, the separation of the conversion rule, the second transformation DB characteristic variable which relates to the characteristics (attribute) of the rule table, the third transformation rule to map the instance variables in the instance of the ontology class, the characteristic variables by the first separator, corresponding to each attribute of the separated fourth variable transform rule, and, to provide a configuration including a fifth conversion rule corresponding to the property variable or variables in the characteristic attribute of the instance variable. By the rule-based ontology conversion apparatus and method as described above, due to the use of the term in the medical field is in many cases used in combination with existing medical term basis, useful for converting existing medical term basis to another word combination approach it can be used. ;
