DBpedia.org is a community effort to extract structured
information from Wikipedia and to make this information
available on the Web. DBpedia allows you to ask sophisticated
queries against Wikipedia and to link other datasets on the Web
to Wikipedia data. The DBpedia knowledge base currently
describes more than 3.4 million things, out of which 1.5 million
are classified in a consistent Ontology, including 312,000
persons, 413,000 places, 94,000 music albums, 49,000 films,
15,000 video games, 140,000 organizations, 146,000 species and
4,600 diseases. The DBpedia data set features labels and
abstracts for these 3.2 million things in up to 92 different
languages; 841,000 links to images and 5,081,000 links to
external web pages; 9,393,000 external links into other RDF
datasets, 565,000 Wikipedia categories, and 75,000 YAGO
categories. The DBpedia knowledge base altogether consists of
over 1 billion pieces of information (RDF triples) out of which
257 million were extracted from the English edition of Wikipedia
