Reporting at the authoring end but I suspect that at the receiving end
the government and NGOs are going to be very interested in tools that
help correlate reported data with other industry news and reports. (01)
Risk management is such a broad category and entails so much information
that I suspect that a system that can identify and explain the increased
risk to a portfolio caused by a flood in southern China and a
demonstration in Cairo on the same day will be hard to resist. (02)

The IBM material that was issued around the "Watson/Jeopardy event"
specifically mentioned M&A target identification and the feeling
expressed by one analyst in an interview, that analysts are inundated
with news, reports and trading patterns/events.

Anything that can get everyone making the same decision at the same time
is bound to cause some very interesting "gold rushes" where there are
more losers than winners but lots of transactions for the
intermediaries. The guys selling logistics in a gold rush almost always
made more money than the miners. (03)
