Keywords-To-SPARQL exploration

Keywords-To-SPARQL exploration is a novel approach for searching and exploring graph-structured data, in particular RDF graph data, using keywords. Our method, instead of providing answers directly from the RDF data graph, generates automatically a set of candidate SPARQL queries that try to capture users information need as expressed by the keywords used. Our approach is tailored to tempolar RDF data, i.e. RDF data that involve temporal properties. To this end, our method is enriched with temporal operators allowing the user to explore data within predefined time ranges. To evaluate our approach, we perform an effectiveness study using two real-world datasets.
