Google Image Labeler, a new feature of Google Image Search that allows you to label random images to help improve the quality of Google's image search results.
How does it work?
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.
For example, image scan be described by the labels such as: bird, sky, soaring, or frigate bird.
Each user who wants to participate will be paired randomly with a partner who's currently online and also using Google Image Labeler. Over a 90-second period, both participants will be shown the same set of images and asked to label each image based on what they see. They'll also be shown words that can't be used as labels. Both participants can add as many labels as they want until one of them matches a partner's label. After there's a match, they'll see a new image and continue the cycle, until time runs out. Contributors will also see points they've earned throughout the session
What is required to participate?
Just an interest in helping Google improve the relevance of image search results for users like yourself. Although you do not have to log in to your Google account to help, logging in will allow you to keep track of your points. You can also choose to provide a nickname, or you can remain anonymous.
