Microsoft is taking on Google, at least in its news. The New Scientist says Microsoft is testing a a news-gathering web site that tailors the stories selected to individual users. Once MSN Newsbot is fully functional, Microsoft says the site will personalise results within 10 minutes of a user starting to browse.Microsoft is not revealing exactly how its site will work. But experts say there are several possible types of algorithm that could be used. One is similar to those Amazon.com uses to recommend additional books a buyer might like. This algorithm analyses the other choices of people who have already bought the first book. A news site would instead group articles according to the reading patterns of previous users.
