A RULE-BASED ONTOLOGY CONVERTING DEVICE FOR CONVERTING FROM RELATIONAL DATABASE TO AN ONTOLOGY INSTANCE AND THE METHOD THEREOF

摘要

There are the governed ontology converting apparatus of rule and method, for a DB table to be converted to ontology example in a relational database by transformation rule, is related to, table input terminal unit is for receiving DB tables; Receive input ontology class; Rule generates unit, is used to generate a transformation rule, is used to convert DB tables in the example of ontology class (ontology example); Entity is read from DB tables, according to transformation rule, including a conversion entity, it generates ontology example corresponding with entity, wherein the first transformation rule, to draw ontology class table in DB, the separation of transformation rule, second transformation DB characteristic variables, its characteristic for being related to regular chart (attribute), third transformation rule, it draws instance variable in the example of ontology class, pass through the characteristic variable of the first separator, it is corresponding with the 4th variable each attribute of transformation rule separated, there is provided a configuration includes the 5th transformation rule corresponding with attribute variable or the variable in the characteristic attribute of instance variable. Pass through rule-based ontology converting apparatus and method as described above, due to many shells of term in the field of medicine being used in for the combination with existing medical terminology basis, it can be used for existing medical terminology basis to be converted to another phrase method that it can be used.
