Hi Tom
Thanks for the pointer, which makes me wonder.
Since Geonames puts a lot of work at building quality links to Wikipedia,
why does not DBpedia simply leverage this work and use those links?
They are available in the RDF, see e.g.,
http://sws.geonames.org/207258/about.rdf it contains two (redundant) links.
<gn:wikipediaArticle rdf:resource="
http://en.wikipedia.org/wiki/Mount_Stanley"/>
<rdfs:seeAlso rdf:resource="http://dbpedia.org/resource/Mount_Stanley"/>
The RDF dump of Geonames is not optimal, though (it's the concatenation of
all individual RDF descriptions, hence heavy and verbose).
It is simpler to parse the alternate names file
http://download.geonames.org/export/dump/alternateNames.zip
which contains the wikipedia links as "alternate names" with the "language"
link. Quite ad hoc, but efficient.
Whichever way, you don't need any fine-tuned matching algorithm, just
harvest 400,000 triples that are already there.
Best
Bernard
