Here a new thread in simile, a semantic web list serve, which might interest those involved in extracting geographic names.

Some further ideas along these lines. What about scraping information about geograpic places like countries and cities from Wikipedia and linking the data to geonames (http://www.geonames.org/ontology/)? Something like http://XXX/wikipedia/Embrun owl:sameAs http://sws.geonames.org/3020251/ The Wikipedia articles about countries and cities all follow relatively similar structures (for instance http://en.wikipedia.org/wiki/Berlin) so it should be easy to scrape them. They already contain links to other places, like the Boroughs and localities in Berlin, which could easily be transformed to RDF links. Many places have geo-coordinates which together with the place name allow scrapers to automatically create links to localities from geonames. Wikipedia is GNU, thus there aren't any problems with licensing as with the Google and Amazon data. As most articles follow the same structure, an approach to implement such a information service could be to: - Use a crawling/screenscraping framework that fills a relational database with the information from Wikipedia. - Use D2R Server (http://sites.wiwiss.fu-berlin.de/suhl/bizer/d2r-server/) to publish the database on the Web and to provide a SPARQL end-point for querying. I once read about some pretty sophisticated screen-scraping frameworks that fill relational databases with data from websites but forgot the exact links. Does anybody know?
