DBpedia: a nucleus for a web of open data 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 datasets derived from
Wikipedia and to link other datasets on the Web to Wikipedia
data. We describe the extraction of the DBpedia datasets, and
how the resulting information is published on the Web for human-
andmachine-consumption. We describe some emerging applications
from the DBpedia community and show how website authors can
facilitate DBpedia content within their sites. Finally, we
present the current status of interlinking DBpedia with other
open datasets on the Web and outline how DBpedia could serve as
a nucleus for an emerging Web of open data.
