Incomplete Information in RDF
Charalampos Nikolaou, Manolis Koubarakis · arXiv (Cornell University) · 2012
We extend RDF with the ability to represent property values that exist, but are unknown or partially known, using constraints. Following ideas from the incomplete information literature, we develop a semantics for this extension of RDF, called RDFi, and study SPARQL query evaluation in this framework.
