DBpedia 3.9 is up and going. Word came today from Christian Bizer and Christopher Sahnwaldt that the new release boasts an overall increase in the number of concepts in the English edition from 3.7 to 4 million things, thanks to being based on updated Wikipedia dumps from the spring of 2013.
Other numbers to impress:
- Of the 4.0 million things in the English version’s knowledge base, 3.22 million are classified in a consistent ontology, including 832,000 persons, 639,000 places, 372,000 creative works (18,500 video games!), 209,000 organizations, 226,000 species and 5,600 diseases.
- With localized versions of DBpedia available in 119 languages, a total of 24.9 million things are described.
- Taken all together, DBpedia 3.9 encompasses 2.46 billion pieces of information (RDF triples), 470 million of which were extracted from the English edition of Wikipedia and 1.98 billion from other language editions.
- With the aid of the mappings wiki, new classes and properties to the DBpedia ontology were added to the tune of 529 classes, 927 object properties, 1290 datatype properties, and more.
- Now there are type statements for Wikipedia articles without infoboxes, inferred based on the link structure within the DBpedia knowledge base using an algorithm. Today you’ll find type information for 440,000 concepts that previously were not typed.
The new release also now features links pointing from DBpedia concepts to Wikidata concepts, according to he post, and has updated the links pointing at YAGO concepts and classes. It also updates the RDF link sets pointing at Freebase, GEOnames, GADM and EUNIS Linked Data sources.
