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.
