This is something I've been trying to figure out for a while now. On some websites you'll see recommendations based off of preferences or activity. On Amazon.com I get all kinds of book recommendations based off of my past purchases.
So obviously Amazon stores my transaction history in a database, along with all the rest of their customers. It could possibly just choose a random number of my book purchases, search other customers that made the same purchase, and display the most common books that other people bought.
I don't think this is the case though because the recommendations are always very relevant. So do they also filter by author and genre?
I guess I'm not too sure. If anyone knows how this kind of stuff works, could you please explain the process?
