At Sporcle.com you can play hundreds of trivia games: name all the countries in Africa, name all the elements in the periodic table, and so on. But some poor schmuck has to create these games by hand. Using semantic information available on Freebase, you can create an automated Sporcle. Build a trivia game where you enter a movie and then have to type as many actors names from that movie as you can. Some scripts are available as a starting point at http://courses.ischool.berkeley.edu/i290-4/f09/resources/10_20_exercise/freebase_trivia.html NOTES - You can use Freebase Suggest with type '/film/film' to allow the user to enter any movie name he or she wants. - Once you have a movie, you'll want to get the actors for that movie. Play with the Freebase Query Editor to figure out how to use the semantic web to get the actors that star in that movie. http://www.freebase.com/app/queryeditor - You can divide up the work however you like in your group. You might have one person make the interface to let the user enter a movie name, while another person figures out how to get the actors' names from Freebase while another makes the interface to guess actor's names.
