ABSTRACT
PreferenceSQL is an SQL extension for standard relational databases supporting soft constraints and is used to find relevant data intuitively. Meanwhile, the Semantic Web has interoperability advantages and helps to retrieve information with machine-readable data. We use the benefits of both technologies by combining preferences from SQL with SPARQL, the query language of the Semantic Web. This work provides implementation details in Apache Jena for the new composite called 'PreferenceSPARQL'. Furthermore, we contribute comprehensive benchmarks that show which preference algorithm is best suited for our approach.

RDF, Jena, SparQL and the 'Semantic Web'
SIGUCCS '09: Proceedings of the 37th annual ACM SIGUCCS fall conference: communication and collaborationThe Resource Description Format (RDF) is used to represent information modeled as a "graph": a set of individual objects, along with a set of connections among those objects. In that role, RDF is one of the pillars of the so-called Semantic Web. This ...
