US online DVD rental service Netflix Inc has announced a version of the Longitude prize for film geeks – a $1m (£529.6m) bounty to the first person to develop software to improve its movie recommendation system by 10%.

The full story is posted in the Guardian and on the NetFlix Prize site.

The current system works by making predictions based on correlations between user feedback (as described in this interview).

I’ve set up a team so that i could check out the data. if anyone wants to take a look at it just let me know (even though its rather big ~665MB).
