Amazon's Mechanical Turk 375

rscoggin writes " has a new program that wants you to 'Complete simple tasks that people do better than computers. And, get paid for it.' (example: 'Is there a pizza parlour in this photograph?'). For each task you complete you get a small payment, usually ranging from a few cents to a little under a dollar. It's named the Amazon Mechanical Turk after a famous hoax from the 19th century. Kill time and get paid in tiny increments to boot!" Similar to Google Answers, there seems to be a reliability ratings system and some incentives.

      Subject: Thesis Oral - Luis von Ahn

      November 2, 2005
      Luis von Ahn
      12:00 PM, 3305 Newell-Simon Hall
      Thesis Oral
      Title: Human Computation


      Tasks like image recognition are trivial for humans, but continue to
      challenge even the most sophisticated computer programs. This thesis
      introduces a paradigm for utilizing human processing power to solve
      problems that computers cannot yet solve. Traditional approaches to
      solving such problems focus on improving software. I advocate a novel
      approach: constructively channel human brainpower using computer games.
      For example, the ESP Game, introduced in this thesis, is an enjoyable
      online game -- many people play over 40 hours a week -- and when people
      play, they help label images on the Web with descriptive keywords. These
      keywords can be used to significantly improve the accuracy of image
      search. People play the game not because they want to help, but because
      they enjoy it.

      I introduce three other examples of games with a purpose: Peekaboom,
      which helps determine the location of objects in images, Phetch, which
      collects paragraph descriptions of arbitrary images to help
      accessibility of the Web, and Verbosity, which collects common-sense
      knowledge. I also show that, in principle, every problem that could be
      solved by a computer, today or in the future, could be solved using
      enjoyable computer games.

      In addition, I introduce CAPTCHAs, automated tests that humans can pass
      but computer programs cannot. CAPTCHAs take advantage of human
      processing power in order to differentiate humans from computers, an
      ability that has important applications in practice.

      The results of this thesis are currently in use by hundreds of Web sites
      and companies around the world, and some of the games presented here
      have been played by over 100,000 people. Practical applications of this
      work include improvements in problems such as: image search,
      adult-content filtering, spam, common-sense reasoning, computer vision,
      accessibility, and security in general.

    Maybe it's just me, but it seems that it's not really worth it. Consider the following task, for example:

    Your task is to create a new product description for a product in the Automotive catalogue. The Product Description provides an additional opportunity to tell the customer about the product. This HIT will require some product research to complete. Approval depends on following the instructions and the quality of your submission, determined by a manual review.

    Guess how much you get paid for that. 2 dollars? 3? That wouldn't be unreasonable, I think, considering that you're supposed to write an entire product description from scratch for which additional "research" is required. The actual amount paid is only 65 cents, though.

    Maybe it's just me, but if I check to see how much I need to work in my regular job to make 65 cents, then it does not make any sense to invest more than a few minutes into a task like this, and it seems that it would take more than that to actually complete it. The fact that there's a review required afterwards doesn't exactly make things better, either - if what you did gets rejected, then you've essentially worked for nothing (I wonder if there's anything that keeps amazon from still using your description in this case, too...).

    In other words, the whole thing seems like a good idea in theory, but it won't really take off until they're willing to actually pay you a reasonable amount.

      Ah, but I think you miss the point. How much to you get paid for a couple minutes at your regular job? Add 65 cents to that, and that's how much you'll get paid at your normal job to slack off and surf Amazon.

      Not to mention that this is the type of thing a copywriter at a marketing firm gets big bucks to do, so essentially you are doing their job for free for Amazon.
    • I agree. The jobs that really are trivial pay nothing and the ones that pay aren't at all trivial. 65 cents or 75 cents isn't nearly enough for what they are asking.
    • I don't know if all of the tasks are going to be from Amazon. It looks to me like anyone can submit "work" through the API, and the market will decide what gets done and what does not. If that 65 cent job sits long enough, and Amazon wants to get it done, they'll pony up more cash until someone thinks it's worthwhile.

      So basically, if it takes you 5 minutes to write a brief product description, and you churn through them all day, you're making $7.80, which is better than minimum wage. Not a good proprosition if you're clueless about auto parts and have to research everything as described, but I don't think that's the intended optimal target for completing the task (although it someone's dumb enough to spend half an hour or more per description for a crappy hourly wage, they're more than welcome). The optimal target to take up that task is someone who already knows a lot about car parts. Chances are if you're an Autozone (auto parts store chain) employee, you could get most of the descriptions done in under 5 minutes with little to no side research, because you already have the domain-specific knowledge. That's the guy who will be drawn to answer that question.

      So the key to making effective money at this scheme is to skip tasks that you don't think you're "better than average" at - kinda like the job marketplace in real life.

      I did nine 3-cent HITs in about 5 or 6 minutes, so that's about 3.25/hour. The lag for me was in waiting for the images to download and clicking on the "Accept HIT" button repeatedly.

      There is an API, maybe if someone made a page that just displays the images and sends in the result when you click on the image instead of having to click twice for each HIT, you could go faster and make much more money.
    • At $0.03 cents/hit, you'll want to aim for around 5 sec/hit to earn about $20/hr.

      If it takes you more than 10 or 15 seconds from the instant you read the description for a hit to the instant you are available to read the description for the next hit after successfully completing the first one, it's not really worth your time (at least, IMHO).

    After a quick review of the available tasks, I must say this looks like a huge scam. Most of the tasks are marketing oriented (e.g. copywriting, photo manipulation), for which experienced contractors get paid $30 to $50 per hour.

    Only 75 cents to research and write a complete automotive product description? Are they kidding? Sure, they say I can copy the description from the manufacturer's Web site, but my time is still worth more than that. Besides, I think it's the responsibility of the manufacturer to make sure their Amazon listing is correct. That's how they do it on IMDB.

    I can only hope the program will make more sense as they add more requesters and more tasks.

    Rather than think about how much you could make per hour on this, think about how much your time is worth. Are you worth $65,000 per year? Maybe you're worth more or you value your time more? In any case, at $65,000 per year, you make about $0.52 per minute.

    It reminds me of a little semi-scam some company had going in my town a few years back. . .

    "You are invited to participate in a screen test of a new television series!"

    People would go down and be a test-audience for a television pilot, and then fill out a questionnaire at the end. People, loving their TV culture, were tickled pink to be asked to do this. --Heck, they were even paid something like $15 for their participation!

    So, a buddy of mine went to see what it was all about. . .

    Basically, some marketing research firm had acquired the rights to an old pilot which never made it to air. They played this for people, and also played a bunch of adverts during the commercial breaks. The questionnaire asked a few boring questions about the pilot, but it also asked a curiously high number of questions about the ad spots. Stuff like, "Which of the two detergent packages in the ad did you find more appealing? The Blue or the Red?"

    --Obviously the whole contrivance was designed to test market, uh, marketing.

    There was an interesting article a while back about a Collaborative Human Interpreter (CHI). []

    The idea is to harness this kind of thing to develop software for the global brain. []

    I like the Mechanical Turk service. It's just like my CHI proposal from half a year ago made real. .html []

    While most of the comments here seem to focus on the Worker side of this (those getting paid for answering simple questions), there's also the Requester side -- programmers tapping into the power of "fake" (but working!) AI. (Ladies and gentleman, we present you the global brain... it can think for you if you micro-pay!) I think we can implement many new programs/ websites in completely new ways, and there may even be fresh commercial niche programs coming out of this. Maybe in 50 years, we'll include AMT (or similar services) into our software as naturally as we now include, say, SQL.

    I wish the site was working better at the moment (even before it has been Slashdotted, it was behaving strangely), and I wish it wouldn't ask me for a US bank account (being from Germany, that kinda hinders me from working with it).

Information is the inverse of entropy.
