The linked open data community continuously releases massive amounts of RDF (Resource Description Framework) data that shall be used to easily create applications that incorporate data from different sources. Inter-operability across different sources requires links at instance- and at schema-level, thus connecting entities on the one hand and relating concepts on the other hand. State-of-the-art entity- and ontology-alignment methods produce high quality alignments for two “Nicely structured” individual sources, where an identification of relevant and meaningful pairs of ontologies is a precondition.
