More on Amazon’s A9 and collaborative filtering

a9More on Amazon’s A9 and collaborative filtering: Chris Sherman, associate editor of Search Engine Watch, takes a look at A9 and while he doesn’t link to my previous post raising the topic, he addresses the collaborative filtering potential I discussed then.

Highlights from Chris:

Another interesting feature in search results is the “site info” button. Mouse over this button and you’ll see a pop-up window with information about the web site provided from Amazon subsidiary Alexa, including traffic rank, number of sites that link to the site, speed, and how long the site has been online.

You’ll also see the collaborative filtering process that Amazon does so well with products on its own sites, “connecting the dots” between users. “People who visit this page also visit” shows you the top three sites that Alexa toolbar users have also visited.

For the time being, A9 does not use this collaborative filtering to influence or alter the Google results it displays, though it certainly may in the future.

So, for the record, my early prediction that one day we will see the Amazon’s amazing collaborative filtering skills incorporated into A9 search results, is in the “certainly may in the future” category.

I will, for the record, state that I believe those collaborative filtering algorithms are currently running in the background and that “in the future” is conceivably not too far off. Why should it be?
