Thomas, Denny, Sebastian, Thomas, and I have published a paper which was
accepted for the industry track at WWW 2016. It covers the migration
from Freebase to Wikidata. You can now read it here:

Is it possible that you have actually used the flawed statistics from the Wikidata main page regarding the size of the project? 14.5M items in Aug 2015 seems far too low a number. Our RDF exports from mid August already contained more than 18.4M items. It would be nice to get this fixed at some point. There are currently almost 20M items, and the main page still shows only 16.5M.

Numbers are off throughout the paper. They also quote 48M instead of 58M topics for Freebase and mischaracterize some other key points. They key number is that 3.2 billion facts for 58 million topics has generated 106,220 new statements for Wikidata. If my calculator had more decimal places, I could tell you what percentage that is.
