I did my own tests with Google+. Some results: - Google+ queues images for recognition. Results improved steadily over 72 hours. - Google+ does not use OCR of text in the images. That surprised me. But perhaps it's a privacy issue. - Google+ does use information gleaned from elsewhere on the web. Words that were associated with the same images on Flickr would turn up those very pictures on Google+. - Oddly, Google+ does not use information associated with those images on Twitter. - Google probably uses EXIF data married to a database of location names. - The much-vaunted feature recognition is impressive, better than any other system, but for me did not achieve creepy levels of intuition. http://neilk.net/blog/2013/05/23/testing-google-photos-ai/ http://neilk.net/blog/2013/05/23/testing-google-photos-ai/
