<p>The illusion people have is that you got an algorithm and you feed it data it will always be right. But it’s only right if the assumptions which go into the algorithm are still valid, or you need a self organizing system which knows about the assumptions. Something that companies blindly using “big data” will have to learn the hard way. People who trust the the “data” without knowing about the assumptions will be in for a surprise.</p> <p>- Comment from Ronald on &ldquo;Google&rsquo;s Flu Snafu&rdquo;</p> — <a href="http://gigaom.com/2013/02/14/googles-flu-snafu-and-the-reliability-of-web-data/" target="_blank">http://gigaom.com/2013/02/14/googles-flu-snafu-and-the-reliability-of-web-data/</a>
