Algebras of relations were shown useful in managing ontology alignments. They make it possible to aggregate alignments disjunctively or conjunctively and to propagate alignments within a network of ontologies. The previously considered algebra of relations contains taxonomical relations between classes. However, compositional inference using this algebra is sound only if we assume that classes ...

The Semantic Web relies on the creation of rich knowledge bases which link data on the Web. Having access to such a knowledge base enables significant progress in difficult and challenging tasks such as semantic annotation and retrieval. DBpedia, the RDF representation of Wikipedia, is considered today as the central interlinking hub for the emerging Web of data. However, DBpedia still displays...

Reports of cyanobacterial blooms developing worldwide have considerably increased, and, in most cases, the predominant toxins are microcystins.
