SYSTEM AND METHOD FOR SPARQL-QUERY PROCESSING USING PARAMETRIZED-SPARQL-QUERY IN DBMS-BASED SYSTEMS

摘要

The present invention relates to a Database Management System (DBMS)- based Semantic Web query system and method using parameterized SPARQL queries. The present invention is configured to include output means that creates a parameter list from a SPARQL query statement, converts the query statement into an SQL statement and stores a PREPARED STATEMENT (PS) object in association with the SQL statement, thereby outputting query results. Accordingly, the query time of a Semantic Web service can be reduced, thereby improving QoS.
