Using SPARQL/UPDATE to Extend RDB-to-RDF: A Mapping Approach
Yanping Chen, Qian Yang · International Journal of Database Theory and Application · 2014
Converting a huge amount of Web data stored in databases to semantic data is a critical requirement for the development of current Web.The literal to URI and implicit information issues existing in some traditional approaches of mapping Relational Database (RDB) to RDF are studied in this paper.In order to solve the above problems, SPARQL/UPDATE is used to extend the traditional approaches.This extensible approach not only solves the literal to URI problem but also gives methods to process implicit information with rules in the original RDF document.Experimental results show that the new approach enable semantic query engines to find more exact results.
