Query execution using link-traversal is a promising approach for retrieving and accessing data on the web. However, this approach finds its limitation when it comes to query patterns such as rdf:type ex:Employee, where one does not know the subject URI. Such queries are quite useful for different application needs. In this paper, the authors conduct an empirical analysis on the use of such patterns in SPARQL query logs. They present different solution approaches to extend the current linked open data principles with the ability for inverse link traversal.
