COLLABORATIVE FILTERING SOFTWARE

The latest issue of the Economist has a feature called Technology Quarterly. It was an interesting article on how "collaborative filtering software" works, e.g., Amazon's recommendation service ("people who bought this item also bought..."). The article, United we find, is premium content for subscribers, but you could read the section in PDF. For more on this topic, read Greg Linden's post, The Economist on personalization.
