DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows users to ask expressive queries against Wikipedia and to interlink other datasets on the Web with DBpedia data.


[edit] The DBpedia Dataset

Wikipedia articles consist mostly of free text, but also contain different types of structured information, such as infobox templates, categorisation information, images, geo-coordinates and links to external Web pages. This structured information can be extracted from Wikipedia and can serve as a basis for enabling sophisticated queries against Wikipedia content.

As of November 2008, the DBpedia dataset describes more than 2.6 million things, including at least 213,000 persons, 328,000 places, 57,000 music albums, 36,000 films, 20,000 companies. The dataset features labels and short abstracts for these things in 30 different languages; 609,000 links to images and 3,150,000 links to external web pages; 4,878,100 external links into other RDF datasets, 415,000 Wikipedia categories, and 75,000 YAGO categories.[1]

The DBpedia project uses the Resource Description Framework as a flexible data model for representing extracted information and for publishing it on the Web. As of November 2008, the DBpedia dataset consists of around 274 million RDF triples, which have been extracted from the English, German, French, Spanish, Italian, Portuguese, Polish, Swedish, Dutch, Japanese, Chinese, Russian, Finnish and Norwegian versions of Wikipedia.

The DBpedia dataset is available under the terms of the GNU Free Documentation License.

The DBpedia dataset is interlinked on RDF level with various other Open Data datasets on the Web. This enables applications to enrich DBpedia data with data from these datasets. As of November 2008, DBpedia is interlinked with the following datasets: Freebase, OpenCyc, UMBEL, GeoNames, Musicbrainz, CIA World Fact Book, DBLP, Project Gutenberg, DBtune Jamendo and Eurostat as well as US Census data. See DBpedia website and W3C SWEO Linking Open Data Community Project for details about interlinked datasets.
