Amazon Recommends...

Lately I've undertaken an effort to catalog the vast amount of media that I have collected in some better way.

And conincidentally, last night I got an e-mail from Amazon.com that said, in essence, "an author whose books you've purchased more than once has written a new book, and we would like you to give us money for it."

And I thought about that proposition and said "Sure, why not?"

I can't say I'd ever noticed that Amazon recommends "stuff" to people before.

And since I had a whole list of the CDs, books and DVDs that I own on my computer screen, I thought it would be amusing to see more of Amazon's recommendations.

Amazon will recommend up to 455 things at a time. Books, music, DVDs, even electronics or houseware-type items if you've purchased any.

Personally I like to buy books and CDs used when possible, and I get my DVDs through netflix. Over the years I've spent only a little money at Amazon (a couple hundred dollars a year, maybe, which doesn't go very far when $50 computer books are included).

But the recommendations it gave me are eerily accurate. By my count, out of the basic 455 recommendations it gave me, I already owned 390 of those items. Some of the recommendations were truly obscure things. It's not like they were all mainstream movies or bestselling books.

I went and looked at my customer history. It said I had purchased 70 items from amazon over a 5-year period, many of them from the Zshops (secondhand or affiliate sellers).

But from those 70 items and who knows how much consumer datamining, Amazon's recommendations were around 85% accurate.

I'm really curious about this in a lot of ways. One part of me wants to tell Amazon everything I own, just to see whether the recommendation engine would get more accurate. Another part is repulsed by the fact that whatever expert system or datamining technique they are using knows me THAT WELL.

I know these things can be done of course. But this is the first time I've really looked at what these systems actually do.

Somewhere in time.
There are many systems like this, but I'd hazard a guess that few are this accurate. Jeff B. is known to be obsessive, a stickler for numbers and facts. So you can be sure that they've worked really hard on this one to perfect their mining and predicting techniques. And from what I've read, they never stop refining and improving their sw. While I'm generally ultra paranoid about my privacy, I feel a lot more comfortable with AMZ than I would with another corporation.

I've received several emails over the years from them recommending one item or another, and have never paid much attention to them. I should probably go there and see what recommendations they come up with for me.

I can only assume you don't care about your own privacy any more. The concept of telling any company everything I own make me shiver with dread. It's all very nice that you trust Amazon so much but think and remember what has been reported stolen from companies such as the credit reporting industry that is legally obligated to protect privacy.

On the other hand I am a realist -- They already know everything to be known about me ... But that doesn't mean I want to confirm it for them.

So the question is are you insane or simply oblivious because privacy matters: At least to me.

There is of course middle ground between being oblivious to security and being paranoid and obsessive about security.

Typically it is known as calculated risk.

I hate to say it, but there is one other possibility: perhaps you are more predictable than you think?

Just a thought. Based on your posts over the years I can't help but think there's no way that's really a possibility, but then what do I know compared to the mighty Amazon?

One of the Amazon recommendations I got was a Naxos release of Paul Creston's first three symphonies.

Paul Creston wrote maybe 3 significant works in his life and is probably more important as a teacher of other composers. But looking at the "Why was I recommended this?" window, I see that Amazon has determined that I like tonal quasi-romantic composers from the first half of the 20th century based on my purchase of a CD of the music of Amy Beach (another obscure composer, which is why I had to order the CD from Amazon to begin with) and a book about Samuel Barber.

But this expert system, or whatever it is, mated my interest in a book with interest in music, and not only that, it "knew" the similarity in the musical styles of each composer involved. It extracted a preference from this, and it was correct. I do like Paul Creston's music as well.

That's pretty damned impressive in my opinion.

And yes Buck, Western Digital needs to apologize to a lot of people for continuing to make hard drives. They should go back to video cards. At least I don't remember a WD video card breaking 6 months after I bought it. :p

No, they didn't break 6 months after you bought them, they just didn't work half the time straight out of the box because of compatibility reasons. :D

The difference is that the credit reporting industry makes their money by selling all our data to external parties, including criminals. And recently with places such as Choicepoint, they aren't even controlled by the FCRA and have no obligations regarding privacy or security at all!

I can't see Amazon selling their customer lists or data to anyone else.

I've never visited Amazon.com, but the above tells me that their pr0n material section must be fairly large.

Why not? Amazon's privacy policy lets them do whatever they want with the info they collect about you.

Perhaps, but in any case the amazon data is not as crucial, since it doesn't contain SS numbers, all your credit history/accounts etc.

Oh, but if it contains your name, address, phone number (highly likely)then it can be sold to someone that does have your SSN...

Big brother is here and already knows all.

LOL... Nah, Merc isn't predictable at all...

Yes, it is. It's a marketer's wet dream. It's a dream of mine to be able to model consumer behaviour, product adoption, revenue potential, etc. Most of the time we get so caught up with the day to day operational activities of our jobs that we don't get time to develop undeniably cool things like that. Well, I can't feel that bad, because management generally wants to run as lean as possible and restrict headcount. Sure, that reduces payroll expenses, but they'll never get breakthrough improvements without giving people time to create.

Well, after 5 years of faithful service, my WD153BA has died. I suspect it was from the same electrical surge that caused my motherboard's capacitors to explode, but it could have been mechanical in nature as the drive has been whining for the last year and a half.
