DBpedia es un esfuerzo comunitario para extraer información estructurada a partir de Wikipedia y hacer que dicha información esté disponible en la web. DBppedia permite hacer preguntas sofisticadas a Wikipedia así como conectar otros conjuntos de datos en la web con los datos de Wikipedia. Con ello, DBpedia espera facilitar que la gran cantidad de información de Wikipedia pueda usarse de nuevos modos interesantes y que pueda inspirar nuevos mecanismos para navegar, conectar y mejorar la propia enciclopedia, contribuyendo, en definitiva, a crear la 'next web'. Se trata de una caso de Open Linked Data Web o de Web Semántica en la práctica. Sin duda, muestra cómo será el futuro de internet. 

DBpedia 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 data sets on the Web to Wikipedia data. We hope this will make it easier for the amazing amount of information in Wikipedia to be used in new and interesting ways, and that it might inspire new mechanisms for navigating, linking and improving the encyclopaedia itself (...)

The DBpedia knowledge base currently describes more than 2.9 million things, including at least 282,000 persons, 339,000 places (including 241,000 populated places), 88,000 music albums, 44,000 films, 15,000 video games, 119,000 organizations (including 20,000 companies and 29,000 educational institutions), 130,000 species and 4400 diseases. The DBpedia knowledge base features labels and abstracts for these things in 91 different languages; 807,000 links to images and 3,840,000 links to external web pages; 4,878,100 external links into other RDF datasets, 415,000 Wikipedia categories, and 75,000 YAGO categories. The knowledge base consists of 479 million pieces of information (RDF triples) out of which 190 million were extracted from the English edition of Wikipedia and 289 million were extracted from other language editions (...) 

Within the W3C Linking Open Data (LOD) community effort, an increasing number of data providers have started to publish and interlink data on the Web according to Tim Berners-Lee’s Linked Data principles. The resulting Web of Data currently consists of several billion RDF triples and covers domains such as geographic information, people, companies, online communities, films, music, books and scientific publications. In addition to publishing and interlinking datasets, there is also ongoing work on Linked Data browsers, Linked Data crawlers, Web of Data search engines and other applications that consume Linked Data from the Web. 

The DBpedia knowledge base is served as Linked Data on the Web. As DBpedia defines Linked Data URIs for millions of concepts, various data providers have started to set RDF links from their data sets to DBpedia, making DBpedia one of the central interlinking-hubs of the ermerging Web of Data.
