This does nothing for you but have you try to match the guesses of others, somewhere else in the world. Geez. You just want to do this over and over again.

Clever idea to make a non-automatable task into a game! I hope this is how the future evolves - all the boring/repetitive tasks will be done by machines/computers/robots, and we humans will spend our time having purposful fun.

On the other hand, I find 'scoring by matching' reminds me of all those TV shows I hate - the ones that are won by guessing the most popular answers to questions. There seems something perverse in the idea of a prize for being most average.

Thanks for providing this food for thought.

If I were Google, and I'm not, I'd set up those images/labels so that there would be a retention of all the guesses, despite some of them not being a match. Then I'd run the image again at another time, officially prohibit the use of the already matched guesses, and see what happens. That would recognize the fact that one team member sees very differently, but not necessarily incorrectly, and opens up the chance for further description matches.
