RDivF (RDF + Diversity) is a diversification framework for keyword search on RDF data. In RDF diversification, the main challenges arise from
the fact that the structure of the RDF results, including additional
semantics from the underlying RDF/S-OWL schema, needs to be
exploited. This is in contrast to the case of diversifying
unstructured search results, where the factor of
content (dis)similarity is sufficient.

The RDivF framework exploits several aspects of the RDF data model
(e.g., resource content, RDF graph structure, schema information)
to answer RDF keyword queries with a set of diverse results.
