Federating queries in SPARQL 1.1: Syntax, semantics and evaluation
Given the sustained growth that we are experiencing in the number of SPARQL endpoints available, the need to be able to send federated SPARQL queries across these has also grown. To address this use case, the W3C SPARQL working group is defining a federation extension for SPARQL 1.1 which allows for combining graph patterns that can be evaluated over several endpoints within a single query. In ...
متن کاملTerp: Syntax for OWL-friendly SPARQL Queries
Web Ontology Language (OWL) [5] can be seen as an extension of Resource Description Framework (RDF). The primary exchange syntax for OWL is RDF/XML, and every OWL ontology can be represented as an RDF graph. But there is no standard query language specifically for OWL ontologies. The most commonly used Semantic Web query language is SPARQL [7], which is intended to be used for RDF. Roughly spea...
متن کاملSPARQLAS - Implementing SPARQL Queries with OWL Syntax
Using SPARQL for writing queries on OWL-DL ontologies can be complicated due to its RDF triple semantics. Translating OWL expressions to this semantics is a non-trivial problem. We present SPARQLDL Abstract Syntax (SPARQLAS), a proper subset of SPARQL, to solve this issue by employing the OWL Functional-Style Syntax to compose queries. We illustrate how the translation is made possible by a mod...
متن کاملEvaluation of SPARQL Queries Using Relational Databases
Basic storage and querying of RDF data using a relational database can be done in a very simple manner. Such approach can run into trouble when used on large and complex data. This paper presents such data and several sample queries together with analysis of their performance. It also describes two possible ways of improving the performance based on this analysis.
متن کاملCONSTRUCT Queries in SPARQL
SPARQL has become the most popular language for querying RDF datasets, the standard data model for representing information in the Web. This query language has received a good deal of attention in the last few years: two versions of W3C standards have been issued, several SPARQL query engines have been deployed, and important theoretical foundations have been laid. However, many fundamental asp...
