Yahoo! Music is sponsoring an online competition to predict ratings of 
music. Their training dataset contains over 260,000,000 ratings and over 
625,000 items. The competition runs from March 15, 2011 to June 30, 2011, 
with registration opening on March 1, 2011. www.kdd.org/kdd2011/kddcup.shtml

Please email me if you would you like to join a Rasch team to compete this 
year. There is no money. Requirements include: great ideas, self-direction, 
available time, familiarity with "Facets"-style Rasch analysis, high-end PC 
with fast internet connection, skill in manipulating large datasets and in 
simple computer programming. Time will be short, so team members will work 
in parallel, sharing datasets and findings. Our purpose is to advance Rasch 
techniques, in a similar way as did the Netflix Challenge:
