Towards A Scalable Semantic-based Distributed Approach for SPARQL query evaluation

Over the last two decades, the amount of data which has been created, published and managed using Semantic Web standards and especially via Resource Description Framework (RDF) has been increasing.As a result, efficient processing of such big RDF datasets has become challenging.Indeed, these processes require, both efficient storage strategies and query-processing engines, to be able to scale in terms of data size.In this study, we propose a scalable approach to evaluate SPARQL queries over distributed RDF datasets using a semantic-based partition and is implemented inside the state-of-the
