ABSTRACT

This paper proposes an implementation of SPARQL-DL, which is a query language for OWL ontologies,for query-answering over the OWL ontologies virtually generated from existing RDBs. The proposedSPARQL-DL processor internally translates input SPARQL-DL queries into SQL queries and then executesthe translated queries. There are two advantages in the query processing method. First, another repositoryto store OWL ontologies generated from RDBs is not required. Second, a large ABox generated from anRDB instance is able to be served without using Tableau algorithm based reasoners which have a problem in large ABox reasoning. Our algorithm for query rewriting is designed to create one corresponding SQLquery from one input SPARQL-DL query to minimize the overhead by establishing connections with RDBs.
