Presentation

Welcome to the Esperanto chapter of DBpedia, the first completely automated version of the DBpedia resource.

DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data.

Nowadays, the English chapter of DBpedia is the central hub of the Linked Open Data Cloud, and it is an important link to different datasets. The version of DBpedia you are surfing on is the first experiment to bring the Esperanto language to the Linked Open Data.

The first automatic DBpedia

The English version of the DBpedia knowledge base describes 4.58 million things, out of which 4.22 million are classified in a consistent ontology, including 1,445,000 persons, 735,000 places (including 478,000 populated places), 411,000 creative works (including 123,000 music albums, 87,000 films and 19,000 video games), 241,000 organizations (including 58,000 companies and 49,000 educational institutions), 251,000 species and 6,000 diseases.

To achieve this goal, DBpedia uses a set of mappings between Wikipedia infoboxes and the ontology. In particular, infobox names are mapped to classes, and infobox attributes are mapped to properties. Everyone can contribute to the DBpedia development by adding mappings in the Mappings Wiki. A tool developed by the DBpedia community, the DBpedia Extraction Framework, uses the mappings defined there to homogenize information extracted from Wikipedia before generating structured information in RDF.

In the Esperanto DBpedia project we have populated the Mappings Wiki using a completely automatic approach described here.

Why Esperanto?

Esperanto is a constructed language spoken by about 2M people in the world. The Esperanto Wikipedia is – with its 200K+ articles – one of the biggest Wikipedia for which the DBpedia corresponding chapter has not been created yet. It is ranked 34th in the list of Wikipedias sorted by the number of articles, and it is constantly updated by a community of almost 100K users.
