Economist om the long tail och rekommendationssystem
Economist om the long tail: Profiting from obscurity. Så här skrivs om kopplingen till rekommendationssystem (collaborative filtering):
But how can people find content they want when it is buried far down the tail? Already, a number of mechanisms have emerged, based around user recommendations. Perhaps the best known is “collaborative filtering”, in which purchase histories are analysed to work out what else is likely to interest the buyer of a particular product (“Customers who bought this item also bought...”, as Amazon puts it). This approach allows users to navigate from hits that they know they like to more obscure titles further down the tail. “You need not just variety, but information about variety,” says Mr Anderson. “A long tail without good filters is just noise.” Many people find even the amount of choice on supermarket shelves overwhelming—in large part because there is so little information on which to base a rational choice. But a mere 27 flavours of jam is nothing compared with millions of music tracks or thousands of movies, so providing filters to help people find what they want is vital.
