Games With A Purpose Help With Tasks That Tax Computers 61

Falkkin writes "Luis von Ahn and his team at Carnegie Mellon University have launched GWAP, a new web site for 'Games With A Purpose.' By playing these online games, humans help provide data for problems that are hard for computers to solve, such as computer vision and sound classification. Slashdot has previously covered other human computation projects by Dr. von Ahn, including the ESP Game and reCAPTCHA. The new web site contains a re-vamping of the ESP Game as well as four completely new games." (Falkkin also points to an AP story on GWAP and to coverage at the BBC.)

      Maybe they could make a game about registering then?

      There's actually an incentive: it's apparently a matchmaking service at the same time. You can set in your profile what your age etc. is, and also select what kind of people you'd prefer to play against. Sometimes there's an option to chat with your partner after the game, I assume if you get a high enough score. Not sure how it works, exactly, since I haven't tried it.

    What search engine? Is the information I provide to them free for anyone to use, or is it just for them?

    Isn't this similar to using [ox.ac.uk] porn to solve CAPTCHAs? Or how about the Google image Labeler [google.com]? And for a literary example, this is one part of the plot in Ender's Game, but not as obvious, and a more nefarious.

    Using a large amount of real intelligence can make some problems easier, if a human can do it much easier, and some amount of noise is acceptable in the output.

      It's not surprising this is similar to the Google Image Labeler since that's just a re-implementation of the ESP Game, which is also one of the games available on the GWAP site.

    I'm not knockin the interface, it's great, but if I went to any 12 year old it would bore them to tears after 1 minute, with them whining "Can we play another game?"

    Here's an idea. Give some OLPC's to kids in 3rd world countries. Teach them to read, then pay them $0.01 per problem they solve. Then sell your DB of solutions to Google for $0.03 a solution.

    As far as I can see, this is not making computers smarter. That is, it's not helping to teach them how to do the tasks given novel situations in the future. It's simply using aggregate human interaction to do tasks that are poorly suited for computers to do still--CAPTCHAs and image recognition.

      This distributed work *is* being done so computers can apply your dog tags automatically to other images of dogs. This is just a 'fun' way of getting the massive amount of data needed to do things like that. I'll be impressed when computers are able to tag images without using anything learned from correctly tagged data to do so.

      You missed the point. You can't just magically automate something like object recognition. You can, however, train filters on computers based on how humans identify objects in images.

      The author has an excellent Google Tech Talk where he describes exactly how these games help computers get smarter. Basically, language is a shared set of common knowledge that a single researcher cannot accurately recreate without interviewing everyone. The games are tools to do exactly that. They generate datasets for analysis, and for further game playing. For example, you might find yourself describing the word "preserve" and start with marking it the opposite of destroy, while the partner guesses "strawberry" and "raspberry".

      He's got lots of neat results from that system in the talk. [google.com] Go watch it.

    Isn't this initiative similar to that launched by Chris McKintrey and Pushpinder Singh, both of whom created databases where questions used to aid in trying to give robots personality?

    Didn't both of these projects fail for the same reason?

      The difference between Von Ahn's work and that before it is quite simple: he dresses everything up as a game.

      Games are addictive, and this is why his projects (like the ESP Game) have continued, whereas others have faded away. It's not rocket/computer science, just a good bit of reasoning that creates very good results.

      And there's already people out there testing ways around the system. Spelling out words in hints. The ESP game had a lot of wierd shit like people guessing the same sequence of words. I wonder if they've measured some sort of meme propagation for collusion like that.
  • OK, so I gave FoldIt a go (it's at fold.it). It's based on the idea of using lots of people to do protein folding rather than automating it or giving the task to phDs. The main gameplay elements are two buttons, "shake" and "wiggle." You basically just move the strands around randomly, then push those two buttons until you hit an acceptable score. Maybe there's more depth to it, but that's about all I could surmise.

    Still pretty fun though, and it runs in Wine.

When you email support, do you get a form email back which suggests you try their broken password recovery procedure? There must be a template somewhere that people use to achieve this maximally annoying standard interface.

      • I think the lesson we can draw from this is that it's fantastically easy to make bad user interfaces. The truly horrific thing in this case is that there is no support email that I can find, you have to do support requests on their forum, which is broken, too.

        It's a shame, really, because I was rather enjoying it.

      Actually they're surprisingly fun. It's taken up a couple hours of my time since reading this article yesterday.

      On a side note there is one game called ESP where you and a partner are each shown a picture. You have to guess words until you each have guessed the same word. Often there will be "taboo" words that you can't use. Checkout this screenshot of the image and what gwap felt were necessary taboo words. Screenshot [buffalo.edu]
