The brave folks at Unspam have taken POPFile and years of data surrounding the Sundance Film Festival in attempt to predict the outcome of the 2006 edition. Specifically, they want to get invited to parties, and they've chosen to geek out on data, bend POPFile to their use (boy, that must have been hard work) and try to predict the hits from the festival.
They claim an 81% accuracy over the past festivals and have a nice web site giving their predictions for this year. The predictions also include a breakdown of how the decisions are made indicating the most important (and worst) words to appear in a review of a movie.
There's also movie metadata like the type of film it was shot on, or who reviewed it. That's a very interesting use of POPFile and if they get it right and are invited to all the cool parties I hope they fulfill my wish and put a good word in for me with Neve Campbell.
