How to Become Part of the Machine

Some of the mind-intensive activities or experiments outlined in this recent New York Times article have been selected below:

"Go to Google Image Labeler (images.google.com/imagelabeler) and you are randomly matched with another bored Web surfer — in Korea, maybe, or Omaha — who has agreed to play a game. Google shows you both a series of pictures peeled from the Web — the sun setting over the ocean or a comet streaking through space — and you earn points by typing as many descriptive words as you can. The results are stored and analyzed, and through this human-machine symbiosis, Google’s image-searching algorithms are incrementally refined. . . .

Now a site run by Amazon.com, the Mechanical Turk (http://www.mturk.com/), asks you to lend your brain. Named for an 18th-century chess-playing automaton that turned out to have a human hidden inside, the Mechanical Turk offers volunteers a chance to search for the missing aviator Steve Fossett by examining satellite photos. Or you can earn a few pennies at a time by performing other chores that flummox computers: categorizing Web sites (“sexually explicit, “arts and entertainment,” “automotive”), identifying objects in video frames, summarizing or paraphrasing snippets of text, transcribing audio recordings — specialties at which neural algorithms excel. . . .

How do you categorize Wikipedia, a constantly buzzing mechanism with replaceable human parts? Submit an article or change one and a swarm of warm- and sometimes hot-blooded proofreading routines go to work making corrections and corrections to the corrections."
