Comparative Preferences in SPARQL
2018Sometimes one does not want all the solutions to a query but instead only those that are most desirable according to user-specified preferences. If a user-specified preference relation is acyclic then its specification and meaning are straightforward.

Swip: A Natural Language to SPARQL Interface Implemented with SPARQL
2014The Swip approach aims at translating into SPARQL queries expressed in natural language exploiting query patterns. In this article, we present the main module of the prototype implementing this approach which entirely relies on SPARQL. All steps of the interpretation process which are carried out in this module are indeed completely performed on RDF ...

An Extension of SPARQL for RDFS [PDF]
, 2008 RDF Schema (RDFS) extends RDF with a schema vocabulary with a predefined semantics. Evaluating queries which involve this vocabulary is challenging, and there is not yet consensus in the Semantic Web community on how to define a query language for RDFS. In this paper, we introduce a language for querying RDFS data.

The YASGUI family of SPARQL clients1
Semantic Web, 2016The size and complexity of the Semantic Web and its technology stack makes it difficult to query. Access to Linked Data could be greatly facilitated if it were supported by a tool with a strong focus on usability. In this paper we present the YASGUI family of SPARQL clients, a continuation of the YASGUI tool introduced more than two years ago.

Snap-SPARQL: A Java Framework for Working with SPARQL and OWL
2016We present Snap-SPARQL, which is a Java framework for working with SPARQL and OWL. The framework includes a parser, axiom template API, SPARQL algebra implementation, and graphical user interface components for reading, processing and executing SPARQL queries under the SPARQL 1.1 OWL Entailment Regime.

2010
The goal of the work is to design and implement a SPARQL compiler for the Bobox system. In addition to lexical and syntactic analysis corresponding to W3C standard for SPARQL language, it performs semantic analysis and optimization of queries. Compiler will constuct an appropriate model for execution in Bobox, that depends on the physical database ...
