Re: [Wikidata] Photographers' Identities Catalog (& WikiData)

Thanks, Tom. I'll have to look at this specific case when I'm back at work tomorrow, as it does seem you found something in error. As for my process: with WD, I queried out the label, description & country of citizenship, dob & dod of of everyone with occupation: photographer. After some cleaning, I can get the WD data formatted like my own (Name, Nationality, Dates). I can then do a simple match, where everything matches exactly. For the remainder, I then match names and dates- without Nationality, which is often very "soft" information. For those that pass a smell test (one is "English" the other is "British") I pass those along, too. For those with greater discrepancies, I look still closer. For those with still greater discrepancies, I manually, individually query my database for anyone with the same last name & same first initial to catch misspellings or different transliterations. I also occasionally put my entire database into open refine to catch instances where, for instance, a Chinese name has been given as FamilyName, GivenName in one source, and GivenName, FamilyName in another. In short, this is scrupulously- and manually- checked data. I'm not savvy enough to let an algorithm make my mistakes for me! But let me know if this seems to be more than bad luck of the draw- finding the conflicting data you found. I have also to say, I may suppress the Niepce Museum collection, as it's from a really crappy list of photographers in their collection which I found many years ago, and can no longer find. I don't want to blame them for the discrepancy, but that might be the source. I don't know. As I start to query out places of birth & death from WD in the next days, I expect to find more discrepancies. (Just today, I found dozens of folks whom ULAN gendered one way, and WD another- but were undeniably the same photographer. ) Thanks, David On Tuesday, December 8, 2015, Tom Morris <tfmorris(a)gmail.com> wrote:
