Hi all 2011/9/8 Sarven Capadisli <info@csarven.ca> > Here is a nice: > > <http://dbpedia.org/resource/Montreal> owl:sameAs > <http://sws.geonames.org/6077244/> . > A nice abuse of owl:sameAs indeed :) http://sws.geonames.org/6077244/ is Montr�al *Post Office* since its feature code is S.PO, called simply "Montr�al" by laziness of the data curator ... and mistaken as the city by some dumb script not leveraging geonames classification to sort out homonyms. > http://sws.geonames.org/6077244/ doesn't provide more labels however. > Indeed. No one has taken the time so far to name Montr�al Post Office in other languages. But http://sws.geonames.org/6077243/ which is indeed the *City* of Montr�al, does provide suite a bunch of them. So data curation is needed : - Specify the name(s) of http://sws.geonames.org/6077244/ on geonames side to ease disambiguation (will do it) - Correct the DBpedia dumb matching (I have no power on that one) Cheers Bernard > > -Sarven > > On Thu, 2011-09-08 at 15:49 +0100, Paul Wilton wrote: > > Hi Scott > > http://www.geonames.org is a good source of global Geospatial RDF > > linked data - it is a very large global dataset > > > > > > For the UK: http://data.ordnancesurvey.co.uk is a good option > > > > > > freebase also has a large global geospatial dataset > > > > > > > > cheers > > Paul > > > > > > > > On Thu, Sep 8, 2011 at 3:38 PM, M.
