    Reverse engineering SPARQL queries by Arenas, M, Diaz, G, Kostylev, E

    Published 2016
    “…Semantic Web systems provide open interfaces for end-users to access data via a powerful high-level query language, SPARQL. But users unfamiliar with either the details of SPARQL or properties of the target dataset may find it easier to query by example — give examples of the information they want (or examples of both what they want and what they do not want) and let the system reverse engineer the desired query from the examples. …”

    Querying incomplete information in RDF with SPARQL by Nikolaou, C, Koubarakis, M

    Published 2016
    “…Following ideas from incomplete information literature, we develop a semantics for this extension of RDF, called RDFi, and study query evaluation for SPARQL. We transfer the concept of representation systems from incomplete information in relational databases to the case of RDFi and identify two very important fragments of SPARQL that can be used to define a representation system for RDFi. …”
