Seems to me that ‘personal data mining’ as microsoft calls it, has been around for quite some time in various forms….not sure how they can slap a patent on it in the year 2008.

The data mining component 112 can employ a single or combination of analysis techniques including, without limitation, statistics, regression, neural networks, decision trees, Bayesian classifiers, Support Vector Machines, clusters, rule induction, nearest neighbor and the like to locate hidden knowledge within data.
