Sparklis lets you explore a RDF dataset through a SPARQL endpoint without the need to read or write SPARQL queries. Queries are displayed in natural language syntax, and are incrementally built by clicking suggested query elements, and by inserting them at the current focus. Only relevant suggestions are made, so that empty results are avoided.
