Christian Becker (Freie Universität Berlin) has implemented a wrapper around flickr which generates photo collections depicting DBpedia concepts. See flickr wrappr for details. We have interlinked all DBpedia concepts with the corresponding photo collections. You can now use any Semantic Web browser to navigate from a DBpedia concept to flickr photos depicting it by following the dbpedia:hasPictureCollection property. This means an additional 30-50 million photos are accessible through DBpedia.
For example, click on the URIs below or paste them into your Semantic Web browser:
Photos depicting Brandenburg Gate: http://www4.wiwiss.fu-berlin.de/flickrwrappr/photos/Brandenburg_Gate
DBpedia URI for Brandenburg Gate : http://dbpedia.org/resource/Brandenburg_Gate
