SPARQR : SPARQL Query Recommender Web Service
Due to the sheer size of large knowledge bases, users can hardly know which identifiers are available or useful for the construction of axioms or queries. As a consequence, users might not be able to express their informational need in a structured form. Yet, users often have a very precise idea of what kind of results they would like to retrieve. With SPARQR, we introduce a SPARQL learning web service which is able to learn OWL classes for given positive and negative examples.
We provide a public web demo. It has limited resources. If you are using it extensively just download the release and let it run locally. Thanks.
