Claim:
A machine implemented system for distributing personalized information, comprising: a comparator that determines differences between two or more related information items, and an analyzer that automatically determines a subset of the related information items as personalized information based in part on the differences and as data relating to the information items evolves over time and at least one of: stores the personalized information in a computer storage medium; or displays the personalized information on an output device, wherein the personalized information adds maximum novel information to the subset of the related information, and wherein the subset of information items is at least one of stored in a computer storage medium or displayed on an output device and the analyzer employs the following algorithm: Algorithm R ANK N EWS B Y N OVELTY (dist, seed, D, n) R←seed//initialization for i=1 to min(n, |D|) do d←argmax d i εD {dist(d i ,R)} R←R∪{d};D←D\{d} where dist is a distance metric, seed—seed story, D—a set of relevant updates, d—document, n—desired number of updates to select and R—list of articles ordered by novelty.
