Discovering keys in RDF/OWL dataset with KD2R
Article No.: 9, Pages 1 - 2
Abstract
KD2R allows the automatic discovery of composite key constraints in RDF data sources that conform to a given ontology. We consider data sources for which the Unique Name Assumption is fulfilled. KD2R allows this discovery without having to scan all the data. Indeed, the proposed system looks for maximal non keys and derives minimal keys from this set of non keys. KD2R has been tested on several datasets available on the web of data and it has obtained promising results when the discovered keys are used to link data. In the demo, we will demonstrate the functionality of our tool and we will show on several datasets that the keys can be used in a datalinking tool.

Representing and querying validity time in RDF and OWL
RDF(S) and OWL 2 can currently represent only static information. In practice, however, the truth of statements often changes with time. Semantic Web applications often need to represent such changes and reason about them. In this paper we present a ...
Towards discovering ontological models from big RDF data
ER'12: Proceedings of the 2012 international conference on Advances in Conceptual ModelingThe Web of Data, which comprises web sources that provide their data in RDF, is gaining popularity day after day. Ontological models over RDF data are shared and developed with the consensus of one or more communities. In this context, there usually ...
