The ontologies behind these sources, however, remain unlinked. This paper describes an extensional approach to generate alignments between these ontologies.
Specifically our algorithm produces equivalence and subsumption relationships between classes from ontologies of different Linked Data sources by exploring the space of hypotheses supported by the existing equivalence statements. We are also able to generate a complementary hierarchy of derived classes within an existing ontology or generate new classes for a second source where the ontology is not as refined as the first.

We demonstrate empirically our approach using Linked Data sources from the geospatial, genetics, and zoology domains. Our algorithm discovered about equivalences and 29, subset relationships in the alignment of five source pairs from these domains.
Thus, we are able to model one Linked Data source in terms of another by aligning their ontologies and understand the semantic relationships between the two sources. Skip to main content Skip to sections. Advertisement Hide. International Semantic Web Conference.

By providing those extra links in terms of RDF triples applications may exploit the extra and possibly more precise knowledge from other datasets when developing an application; by virtue of integrating facts from several datasets, the application may provide a much better user experience.
Some of those books are introductory in nature while others are conference proceedings or textbook that address more advanced topics.
