Computers can quickly scan a document for certain words, but a two year old child can find objects in an image better than the most powerful computer. When searching for images on the internet you must rely on the image’s name or description. Google has therefore enlisted the help of humans to give appropriate labels to images on the internet. If you do an image search at Google you might notice the “Try Google Image Labeler” link. When you click on this link you are greeted with these instructions:
You’ll be randomly paired with a partner who’s online and using the feature. Over a 90-second period, you and your partner will be shown the same set of images and asked to provide as many labels as possible to describe each image you see. When your label matches your partner’s label, you’ll earn some points and move on to the next image until time runs out. After time expires, you can explore the images you’ve seen and the websites where those images were found. And we’ll show you the points you’ve earned throughout the session.
It’s actually quite fun.
