Flint, a SPARQL Query Editor
Editors are now available for SPARQL. We present the Flint structured editor which provides syntactic coloration. The editor proposes SPARQL keywords according to the context where you are in the query and guides the user, for example when writing prefixes.

Corese : execute SPARQL queries
The Corese software, developped in the Wimmics team, implements RDF, RDFS, SPARQL 1.1 and enables users to execute SPARQL queries on RDF data.
Gephi and Corese to analyse data on the Web
Gephi and Corese combined to visualize graphs
While integrating CORESE and the Gephi graph platform, Inria enabled this last one to query the Semantic Web to obtain and visualize data. This demo shows how the "Semantic Web Import" plugin enabled us to integrate CORESE and Gephi to obtain and visualize linguistic links between most populated places in the world.
QAKIS : A question-answering service
QAKIS is a question answering service over the linked data of several DBpedia chapters (i.e. from several languages: English, French, German). It allows you to formulate a query in English and obtain a answer directly from the knowledge graph of DBpedia. To do this, QAKIS implements a method to translate a simple English question into a SPARQL query.
