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 ...

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.

An Executable Specification for SPARQL
2016Linked Data on the web consists of over 1000 datasets from a variety of domains. They are queried with the SPARQL query language. There exist many implementations of SPARQL, and this rich ecosystem has demanded a precise specification and compliance tests.

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.

In both conceptions, the common factor (the web) imposes certain requirements: extremely variable scalability (from a home page to community sites to sites that encompass a significant fraction of the web), rapid evolution, radical distribution, arbitrary interconnection and aggregation, and very little validation or other means of control. The demands

The SPARQLING System for SPARQL Queries over GRAPHOL ontologies.
2018In this demo we present the SPARQLING system for SPARQL query building based on the GRAPHOL visual language for ontologies. The characterizing feature of SPARQLING is the idea to preserve and take advantage of the native diagrammatic representation of GRAPHOL ontologies, allowing the user to navigate it, and to construct a graph-based representation of
