Ars Technica reports that Google has begun outsourcing, or “crowdsourcing,” the task of tagging its image database by asking people to play a simple picture labeling game. The game pairs you with a randomly selected online partner, then, for 90 seconds, runs you through a sequence of thumbnail images, asking you to add as many labels as come to mind. Images advance whenever you and your partner hit upon a match (an agreed-upon tag), or when you agree to take a pass.
I played a few rounds but quickly grew tired of the bland consensus that the game encourages. Matches tend to be banal, basic descriptors, while anything tricky usually results in a pass. In other words, all the pleasure of folksonomies — splicing one’s own idiosyncratic sense of things with the usually staid task of classification — is removed here. I don’t see why they don’t open the database up to much broader tagging. Integrate it with the image search and harvest a bigger crop of metadata.
Right now, it’s more like Tom Sawyer tricking the other boys into whitewashing the fence. Only, I don’t think many will fall for this one because there’s no real incentive to participation beyond a halfhearted points system. For every matched tag, you and your partner score points, which accumulate in your Google account the more you play. As far as I can tell, though, points don’t actually earn you anything apart from a shot at ranking in the top five labelers, which Google lists at the end of each game. Whitewash, anyone?
In some ways, this reminded me of Amazon’s Mechanical Turk, an “artificial artificial intelligence” service where anyone can take a stab at various HIT’s (human intelligence tasks) that other users have posted. Tasks include anything from checking business hours on restaurant web sites against info in an online directory, to transcribing podcasts (there are a lot of these). “Typically these tasks are extraordinarily difficult for computers, but simple for humans to answer,” the site explains. In contrast to the Google image game, with the Mechanical Turk, you can actually get paid. Fees per HIT range from a single penny to several dollars.
I’m curious to see whether Google goes further with tagging. Flickr has fostered the creation of a sprawling user-generated taxonomy for its millions of images, but the incentives to tagging there are strong and inextricably tied to users’ personal investment in the production and sharing of images, and the building of community. Amazon, for its part, throws money into the mix, which (however modest the sums at stake) makes Mechanical Turk an intriguing, and possibly entertaining, business experiment, not to mention a place to make a few extra bucks. Google’s experiment offers neither, so it’s not clear to me why people should invest.
