Model for independent use of web ontology storage of SPARQL-to-SQL translation algorithms

This paper proposes a storage-independent model for SPARQL-to-SQL translation algorithms based on a relational view. In the development of Web ontology research, the translation from SPARQL to SQL continues to be an issue. Previous research has focused on an ecient and complete translation from SPARQL queries to equivalent SQL queries. However, these translation algorithms depend on speci c storage structures. When we modify the storage structure, the translation algorithm should also be modi ed to suit the changed storage structure. This has motivated study of the issue of a model for the independent use of storage structures by algorithms. These can then guarantee independence between translation algorithms and storages by generating relational views, and improve the application and usability of the translation algorithm. In addition, this paper presents experiment results showing the accuracy and no data loss rate of query results for di erent storages.
