SYSTEM AND METHOD FOR SPARQL-QUERY PROCESSING USING THE PARAMETERIZED-SPARQL-QUERY IN BASED DBMS

摘要

PURPOSE: A system and a method for SPARQL-query processing using the parameterized-SPARQL-query in based DBMS are provided to reduce semantic web service query time thereby improving service quality. CONSTITUTION: A parameter list generator creates a parameter list from SPARQL(SPARQL Protocol and RDF(Resource Description Framework) Query Language) query. A transforming method(200) makes a PS(Prepared Statement) object correspond to at least one SQL statement, then stores the PS object, wherein the PS object converts the SPARQL query sentence into a SQL(Structured Query Language) statement. A Database Management System(400) outputs result of inquiry using a PS object and the parameter list which is stored corresponding to the converted SQL statement.
