Review of Querying RDF Techniques with SPARQL in Semantic Web Technologies

Efficient querying RDF triples with SPARQL plays an important role in Semantic Web data management. This paper presents a short review of an efficient RDF query to evaluate SPARQL queries, where the reversed index structure is engaged for indexing RDF triples. First, we review the design and implementation of operators on query optimization and evaluation then how it transforms a SPARQL query graph into the optimal query plan by effectively reducing the search space to determine the optimal joining order. This research study is to investigate the performance of the Semantic Data models and patterns for querying RDF data with SPARQL and enrich the techniques to improve performance of the models and patterns efficiently.
