Query Processing Apparatus and Method to use relational database as OWL ontology on semantic web

摘要

The query processing method and apparatus is disclosed for use in Semantic Web OWL ontology into a relational database. Classifies the query received via the query analyzing unit semantic web applications ABox query processing section and TBox / RBox query processing section. TBox / RBox processor sends the native groups reasoning TBox / RBox part of query processing to infer the TBox OWL ontology generated from the schema of a relational database built on pre perform TBox / RBox query processing and query processing requests. The processing unit processes the ABox ABox query processing part based on the metadata for the TBox ontology schema metadata received from the inference machine and native collected from the relational database. Transmits the processing result of the TBox / RBox query processing by groups of extracted data and the results inferred from the native transfer unit relational database query results based on the processing results for the query processing section ABox as semantic web applications. According to the invention, the changes that have separate schema structure built on a relational database and the data transfer process without the need for pre-relational databases can be used as OWL ontologies in the Semantic Web environment. ;
