Good read, I caught in the 3rd paragraph the buildout of information. Noted other releases on apps from CES, startups are plugging into FreeBase as data dump to gather existing knowledge and information from community. http://en.wikipedia.org/wiki/Freebase

"Nuance's aim is to create a highly personalised assistant, building on a large collection of information that will expand over time. This information will be entered by the user, in addition to the software learning from search terms and voice commands. The plan is to also gather information from applications so it can build up an even bigger database of personal preferences."
