Hi, I’m Kevin Murphy, one of the researchers at Google who worked on this project. Just to be clear, KV did NOT involve any private data sources -- it just analyzed public text on the web. (And yes, we do try to estimate reliability of the facts before incorporating them into KV.) Also, KV is not a launched product, and is not replacing Knowledge Graph. Unfortunately, I cannot do a more detailed Q&A here, but if you want more details, please read the original paper here: http://www.cs.cmu.edu/~nlao/publication/2014.kdd.pdf http://www.cs.cmu.edu/~nlao/publication/2014.kdd.pdf. (Note that an earlier version of the work was presented at a CIKM workshop in Oct 2013 (see http://www.akbc.ws/2013/ http://www.akbc.ws/2013/ and http://cikm2013.org/industry.php#kevin http://cikm2013.org/industry.php#kevin).
