Hi Karen Thanks for the code. As far as I can see though it doesn't actually solve my disambiguation problem - since identity_info.php just takes a name as input, it can't guess which of the people with this name is meant other than by using the most commonly referenced one, which in the OCLC data actually seems to often be an amalgam of several people with the name; for example http://worldcat.org/identities/viaf-DNB|100804799 is William Morris, the 18th century African-American engineer whose most widely held works include News from Nowhere, Introduction to Fly Fishing, and Ancient Slavery Disapproved of by God - ie an amalgamation of the various most famous people known by this name. I guess this is just a hard problem overall. Graham On 05/19/11 14:56, Karen Coombs wrote: > Graham, > > I'd advocate using WorldCat Identities to get to the appropriate url > for dbpedia.
