Introducing Wild-card and Negation for Optimizing SPARQL Queries based on Rewriting RDF Graph and SPARQL Queries

Topics: Ontology Discovering, Modelling, Retrieving and the Semantic Web

In Proceedings of the 12th International Conference on Web Information Systems and Technologies - Volume 2: WEBIST, 181-187, 2016 , Rome, Italy

Keyword(s): RDF, SPARQL, Negation, Wild-card, Querying RDF and RDFS Graphs, Query Optimization.

Abstract: In this paper, we extend the SPARQL triple patterns to include two operators (the negation and the wild-card). We define the syntax and the semantics of these operators, in particular, when using them in the predicate position of SPARQL triple patterns. The use of the negation and wild-card operators and thus the semantics are different from the literature. Then, we show that these two operators could be used to enhance the evaluation performance of some SPARQL queries and to add extra expressiveness.
