I think that this discussion really emphasises how bad it is to put this co-ref data in the same store as the other data. Finding data in dbpedia that is mistaken/wrong/debateable undermines the whole project - the contract dbpedia offers is to reflect the wikipedia content that it offers. And it isn't really sensible/possible to distinguish the extra sameas from the "real" sameas. Eg http://dbpedia.org/resource/London and http://dbpedia.org/resource/Leondeon And on the other hand, freebase is now in danger of being undermined by this as well. As time goes by, the more I think this is going wrong. Best Hugh <truncate/>Received on Tuesday, 11 August 2009 21:35:02 UTC
