Developing interfaces to enable casual, non-expert users to query complex structured data has been the subject of much research over the past forty years. We refer to them as as schema-free query interfaces, since they allow users to freely query data without understanding its schema, knowing how to refer to objects, or mastering the appropriate formal query language. Schema-free query interfaces address fundamental problems in natural la...]]></description>

  <description><![CDATA[We need better ways to query large linked data collections such as DBpedia. Using the SPARQL query language requires not only mastering its syntax but also understanding the RDF data model, large ontology vocabularies and URIs for denoting entities.  Natural language interface systems address the problem, but are still subjects of research. We describe a compromise in which non-experts specify a graphical query ``skeleton'' and annotate it with freely chosen words, phrases and entity names. T...]]></description>
