    Eclos, cette vidéo devrait bien te plaire! Non seulement le présentateur a de l’humour, mais en plus il maitrise à fond son sujet. Et quel sujet : comment rendre les jeux plus amusant! Et pourquoi? Pour faire faire des taches rébarbatives à toute cette population de personnes qui s’ennuie et joue sur internet. Comment y arriver? Faut regarder la vidéo :-P!

    Google Blogoscoped spotted the Google Image Labeler game, designed to help Google improve its image search results through tagging. It feels like a catch-up game with human-powered efforts that Yahoo is embracing via Flickr — plus it also looks pretty influenced by the work of Luis von Ahn and his ESP Game.

    The game pits you against someone else. If you see a picture of a car, and you both label it car, you can proceed to the next image. You continue until your time has run out. Here is an image of Horcrux and Barry Schwartz from our blog (rustybrick) scoring 300 points for matching tags on three images.

    Image search has been tough for search engines. They can’t easily tell what an image is about, since there’s no good way to « see » the images and categorize them. Some technologies to recognize faces, colors, shapes, objects and other things are improving. Still, it’s hard with an image of someone like Martha Stewart. Is she a woman, celebrity, criminal or just Martha Stewart? Or all of these? How do you know which one or ensure that all of them are applied.

    Yahoo’s Bradley Horowitz is probably one of the most famous converts from turning to human power over computer power. He’s been cited many times as having originally sought a technological solution to understanding what’s in video and image data, then moved to embrace people power. Here’s one example of that from a Wired article last year:

    Horowitz’s favorite project is incorporating people-powered metadata systems from two other Yahoo! properties: the recommendation technology from Yahoo! Music and the tagging features from Flickr, the photoblogging company Yahoo! acquired this spring. Google’s original stroke of genius was figuring out how to piggyback on human judgment by following the links people make between Web sites. Horowitz is borrowing functionality from two Yahoo! properties to develop something similar for video.

    We’ve just seen Yahoo make more of a commitment to using that human power when it started inserting Flickr results, rather than Yahoo Image results (which are computer sorted), into regular web searches last week.

    Google, of course, has no Flickr to use. Enter the game. It’s designed to get lots of people to quickly label images because they want to have fun. If that concept sounds familiar, it’s because that’s exactly the method behind the ESP Game, created by Carnegie Mellon professor Luis von Ahn.
