Market data providers got it all wrong, big data 2.0

I have seen lots of heated discussion about the development of big data and its potential value generation. It only generates value when you have a holistic view about your client so that the organization can do something about it. It is like asking for a dates, the more you know about the person, the better.

It is true that market data providers such as Bloomberg, Thomson Reuters etc do a good job in opening up the information about your client external to your organization,…

Last October, a colleague and I speculated on how a special, powerful form of predictive analytics would revolutionize presidential campaigning—and, if successful, how it might be poorly received by the public thereafter.
